Validation of the Thomson , Perry and Miller ( 2007 ) Collaboration Instrument in the South African context

People’s ability to collaborate with each other in organisations is becoming a business imperative. Effective collaboration can enhance product innovation and service delivery, and increase efficacy (Barber & Goold, 2014; Miller & Katz, 2014; Patel, Pettitt & Wilson, 2012; Sanker, 2012; Simatupang & Sridharan, 2005). Leveraging these benefits could be of considerable value to South African businesses. A valid measure of collaboration could help South African business leaders optimise opportunities and address obstacles to effective collaboration.


Introduction
People's ability to collaborate with each other in organisations is becoming a business imperative.Effective collaboration can enhance product innovation and service delivery, and increase efficacy (Barber & Goold, 2014;Miller & Katz, 2014;Patel, Pettitt & Wilson, 2012;Sanker, 2012;Simatupang & Sridharan, 2005).Leveraging these benefits could be of considerable value to South African businesses.A valid measure of collaboration could help South African business leaders optimise opportunities and address obstacles to effective collaboration.
Globalisation, technology advancements and the fast rate of change are all catalysts for increased complexity in the business environment (Barber & Goold, 2014;Kaats & Opheij, 2014;Miller & Katz, 2014;Sanchez, 2012).South African organisations face the same complexities as the rest of the world.The country also faces unique challenges, such as electricity shortages, labour unrest, poor quality of education and increasing debt (International Monetary Fund, 2013;World Economic Forum, 2015).Higher education enrolment rates are not foreseen to produce the level of skills required for future competitiveness (World Economic Forum, 2015).These issues place additional pressure on businesses to operate efficiently and innovatively.
Coping with this complexity requires staying abreast of new developments, solving difficult problems and at the same time seizing opportunities.This is not easy for individual entities to achieve alone (Barber & Goold, 2014;Kaats & Opheij, 2014;Woodland & Hutton, 2012).
To deal with this complexity, many organisations are moving from hierarchies to network systems.This change is necessary but can involve complicated interactions, meaning that communication, learning and innovation must be fast and effective (Kaats & Opheij, 2014;Miller & Katz, 2014).A powerful strategy to attain improved results under these conditions is through collaborative partnerships (Barber & Goold, 2014;Kaats & Opheij, 2014;Miller & Katz, 2014;Sanchez, 2012;Thomson, Perry & Miller, 2007;Woodland & Hutton, 2012).This necessitates establishing an environment that fosters a collaborative culture.Further to improving business results, a collaborative culture can also improve employee morale and retention (Murphy, Arenas & Batista, 2014).Exposure to collaboration allows individuals to perform roles other than their own, enhancing selfdevelopment (Sanchez, 2012).People also experience expanded thinking, broadened and diverse networks and inspiration from co-collaborators (Bushe, 2006).Collaboration can also provide strong social connections, which have been found to promote positive mental health (Bond, Lusher, Williams & Butler, 2014).
Conversely, efforts to collaborate can result in failure.There are several potential obstacles to achieving a collaborative environment.Poorly designed partnership agreements usually result in ambiguous roles and the likelihood of poor communication (Patel et al., 2012).Structures, processes and technologies that do not support collaboration can create difficulties (Hudson, Hardy, Henwood & Wistow, 1999;Kaats & Opheij, 2014) as can weak knowledge management (Patel et al., 2012).Collaboration requires significant energy in managing varying priorities, conflicts and territory issues (Sanchez, 2012).Given these challenges, before embarking on collaboration, leaders should assess whether the reward outweighs the effort and establish that all stakeholders share this perception (Marek, Brock & Savla, 2015;Patel et al., 2012).
Evaluation and feedback on how the organisation is progressing towards a collaborative culture is considered to be a valuable endeavour (Majchrzak, Jarvenpaa & Bagherzadeh, 2015;Marek et al., 2015;Murphy et al., 2014;Wong, 2006).Several measurement instruments have been developed over the years, many of which apply to specific industries or disciplines.This study reviewed various collaboration instruments for their suitability for validation in a South African context and application to a general business environment.The collaboration instrument selected for this study was the Thomson, Perry and Miller (2007) Collaboration Instrument.This instrument was based upon a five-factor model of collaboration as illustrated in Figure 1.

Trends from the research literature
Collaboration has been the focus of much scholarly research.The volume of literature suggests a keen interest in exploring this construct.Despite this interest, it is apparent that a common and accepted definition does not exist.In some cases, definitions are specific to certain environments such as education or nursing.This lack of clarity around collaboration is considered an obstacle to supporting and improving collaboration (Hudson et al., 1999;Patel et al., 2012;Thomson et al., 2007).However, there are generic definitions that support similar themes.The following operational definition, highlighting these themes, is suggested for the purpose of this study: collaboration is a combined undertaking between mutually dependent parties that have shared responsibilities on an agreed process with an envisaged outcome to deliver a result considered superior to what the parties could achieve individually (Kaats & Opheij, 2014;Mattessich, Murray-Close & Monsey, 2001;Sanker, 2012;Schwarz, 2006;Thomson et al., 2007).The literature discussion that follows is framed within: • stages of collaboration • theoretical perspectives that have contributed to collaboration • collaboration measurement instruments.

Stages of collaboration
There is a perspective that collaboration occurs in different stages, and hence, it is a developmental process that requires reflection, review and learning (Frey, Lohmeier, Lee & Tollefson, 2006;Gajda, 2004;Peterson, 1991).Peterson (1991) developed a three-stage model of collaboration, namely, cooperation, coordination and collaboration.The premise is that effective collaboration cannot ensue in the absence of cooperation and coordination.This implies that as the group progresses through the stages, effectiveness increases.Gajda (2004) expanded the three stages to five, identifying 'networking, cooperating, partnering, merging and unifying' (Gajda, 2004, p. 71).These are referred to as levels of integration.For each of these levels, there are descriptors under the categories of 'purpose, strategies and tasks, leadership and decision making, and interpersonal communication' (Gajda, 2004, p. 71).These stage descriptors provide a tool to identify current reality and the desired state of collaboration.They also facilitate the design of an implementation plan to work towards each stage of collaboration.Frey et al. (2006) proposed an additional stage in the collaborative process, called 'co-existence'.This is based on the premise that it is possible for a group to exist with no level of collaboration.

Theoretical perspectives contributing to collaboration
A number of organisational theories or concepts explain different facets of collaboration.Gray and Wood (1991) examined specific theories in terms of their contribution and limitations in this regard.D'Amour, Ferrada-Videla, San Martin Rodriguez and Beaulieu (2005) also identified particular theories that they deem as contributors to explaining collaboration.An additional concept that is considered to be linked to collaboration is social capital, which is described as the value gained through reciprocal and trusting relationships, with an important emphasis on mutually beneficial outcomes (Campbell, 2006;Ofori & Sackey, 2010;Pastoriza, Arin & Ricart, 2009;Wollebaek & Selle, 2007).Most of these contributive theories provide insight into some of the reasons why individuals and organisations choose to collaborate.Elements that should be considered prior to entering into a collaboration are highlighted.They also allude to certain conditions that can enable successful collaboration.Table 1 maps these theories against (1) reasons to collaborate, (2) issues to consider prior to collaborating and (3) designing and maintaining conditions for effective collaboration.

Collaboration measurement instruments
Several collaboration measurement instruments as listed below have been developed, which were reviewed for their suitability for this study.Most of these instruments apply to specific disciplines, with few for application in a multidisciplinary context: • Collaboration and Satisfaction about Care Decisions (Gedney Baggs, 1994): An instrument to measure nurse and doctor collaboration while making decisions on patient care.• Collaboration and Trust in an Education Context (Tschannen-Moran, 2001): A measure of collaboration between principals, teachers and parents.• Wilder Collaboration Factors Inventory (Mattessich et al., 2001): A general measure of collaboration.• Collaboration Index: a measure for supply chain collaboration (Simatupang & Sridharan, 2005): A scale to measure collaboration amongst participants involved in supply chains.• Collaboration Measurement Instrument (Thomson et al., 2007): An instrument to measure collaboration in a general business context.• Collaborative Culture Scale (Perez, Peon & Ordas, 2011): A scale that measures the values attributed to a collaborative culture.
• Assessment of Inter-professional Team Collaboration Scale (Orchard, King, Khalili & Bezzina, 2012): An instrument to measure collaboration between teams of health professionals.• CoSpaces Collaborative Working Model (Patel et al., 2012): An instrument designed in the aerospace, automotive and construction industries, applicable to a general business context.
The Thomson, Perry and Miller Collaboration Instrument (Thomson et al., 2007) (Thomson et al., 2007).Of the 56 items tested, 17 proved to have overall and component fit.The authors present their study as a preliminary attempt to measure collaboration with scope for further research.They encourage cross-validation of their instrument on other independent samples.In contrast to other measures, the Thomson, Perry and Miller Collaboration Instrument (Thomson et al., 2007) measures collaboration in general business and not industry-specific settings.For these reasons, this instrument is considered suitable for a validation study.

Problem statement and research objectives
Because there is no evidence of an existing collaboration measure in South Africa, use of an international instrument was considered appropriate.With a limited number of tests developed specifically for South Africa, it is not unusual to make use of international instruments (Foxcroft & Roodt, 2005;Gajda, 2004;Orchard et al., 2012).It is, however, necessary to be cautious when using a measurement instrument originally validated in a different setting (Gregory, 2005).Certain instruments developed in other countries have been empirically tested and proved to have good portability to a South African context (Campbell & Young, 2011;Collings, Valjee & Penning, 2013;De Bruin, Swartz, Tomlinson, Cooper & Molteno, 2004;Vermeulen, Schaap, Mitchell & Kristovics, 2009).However, specific studies support the assertion that not all assessment instruments are suitable for testing in a South African environment without some adjustment (De Klerk, Boshoff & Van Wyk, 2009;Meiring, Van de Vijver & Rothmann, 2006;Van Eeden & Wissing, 2008).
For these reasons, it is required that instruments are appropriately tested for each setting (Donald, Thatcher & Milner, 2014;Foxcroft & Roodt, 2005;Gregory, 2005).This study therefore aimed to validate the Thomson, Perry and Miller Collaboration Instrument (Thomson et al., 2007) in the South African context, with the objective of using it in South African organisations.A secondary objective was to test convergent validity with the norms factor of the Thomson, Perry and Miller Collaboration Instrument (Thomson et al., 2007) with the Trust in Teams Scale (Adams, Waldherr & Sartori, 2008).

Potential value-add of the study
This study could further the body of knowledge on collaboration through testing a conceptual model's reliability and construct validity in the South African context.Validation of the existing instrument could contribute to more reliable measures in the South African context.This may enable organisations to understand the extent to which the factors of collaboration are a strength or weakness in their organisation.
Equipped with this knowledge, leaders could prioritise initiatives to create the conditions that enable improved collaboration.Human resources functions are being called upon to enhance their contribution and become strategic partners to business (Beatty, Huselid & Schneier, 2003).An area where human resources practitioners can increase their value-add to companies is through the provision of human capital measures that support implementation of the business strategy (Beatty et al., 2003;Chrysler-Fox & Roodt, 2014).
Collaboration is an example of one such measure.This is particularly true for South Africa where human resource management has predominantly focused on industrial relations as opposed to increasing organisational effectiveness (Horwitz, 2008).

Method Research approach
A cross-sectional quantitative design was deemed suitable for this study because a numeric description of the opinions of the participants at a specific point in time was required (Cresswell, 2014).The data were subjected to statistical analysis to test the reliability and construct validity of the Thomson, Perry and Miller Collaboration Instrument (Thomson et al., 2007).In order to further establish the strength of the scale, it was deemed of interest to ascertain convergent validity of one of the factors with an existing valid instrument.For this purpose, the Trust in Teams Scale (Adams et al., 2008) was selected to ascertain convergent validity with the norms factor of the Thomson et al. (2007) instrument.

Research participants
This study was conducted in two organisations, an industrial services company and an information and communications technology company.The criterion utilised for the target population was that the respondents needed to be employees who are required to collaborate with other teams or business units.A census sampling approach was deployed, inviting all members of the target population of 4200 employees.

Measuring instruments
The existing questionnaire devised by Thomson et al. (2007) was used for this study.The authors originally developed 56 items for their five-factor collaboration scale.These factors are governance, administration, mutuality, autonomy and norms.Items such as 'Your organisation relies on a formal agreement that spells out relationships between partner organisations' and 'Your organisation feels it's worthwhile to stay and work with partner organisations rather than leave the collaboration' were included.The items are measured on a 7-point scale, varying from 'not at all' to 'to a very great extent'.The scale was subject to validity studies and 17 items were retained for their statistical or theoretical relevance.Standardised lambda coefficients of 0.75 or greater were reported for 14 of the items.The CFA fits were at an acceptable level: RMSEA 0.063 (p = 0.01); RMSEA Cl 0.055-0.072,GFI 0.97 and AGFI 0.96.The five factors were applied in this study.The original survey was designed for cross-organisational collaboration.Because this study was conducted within organisations, the word 'organisation' was replaced with 'team'.
In their recommendations for future research, Thomson et al. (2007) encouraged the addition of new items to enrich the instrument or drawing from the original 56 if deemed appropriate.In this study, 14 items were added to the scale, resulting in 31 items in total.Two items were drawn from the original 56, because of their perceived theoretical relevance.The commitment of resources by collaborative parties is cited as a key factor in effective collaboration (Kaats & Opheij, 2014;Mattessich et al., 2001;Patel et al., 2012).Subsequently, the item 'My team knows what resources (i.e.money, time, expertise) other teams contribute to collaborative endeavours' was re-instituted in the factor: governance.Because effective collaboration is based on the development of relationships (Frey et al., 2006;Gajda, 2004;Mattessich et al., 2001;Peterson, 1991), the item 'Developing long-term personal relationships with other teams is the most important part of collaborating' was re-instituted in the factor: norms.
The remaining 12 new items are discussed below: • Factor: governance.'The leaders of this organisation support collaboration' supporting the theory that leaders perform a critical role in creating and maintaining a collaborative environment (Kaats & Opheij, 2014;Patel et al., 2012).• Factor: governance.'Rules of engagement are agreed for all collaborative endeavours I am involved in'.The theory suggests that the dynamics of the group can make or break collaboration (Kaats & Opheij, 2014).Hence agreeing the values, norms and communication style of the group can help to reduce anxiety (Kaats & Opheij, 2014;Wheelan, 2005).• Factor: governance.'Other teams adhere to agreed rules of engagement during collaboration'.It is necessary to provide a reference for group process monitoring and feedback (Kaats & Opheij, 2014;Wong, 2006) which the rules of engagement serve as.• Factor: administration.'The existing organisational structure supports collaboration between teams'.A supporting organisational design and policies and processes are cited as important structural considerations of effective collaboration (Hudson et al., 1999;Kaats & Opheij, 2014;Patel et al., 2012).It was decided to separate policies and procedures from structure in the items, because they are different dimensions.Number 5 that follows relates to the policies and procedures item.• Factor: administration.'The existing organisational policies and procedures support collaboration between teams'.
• Factor: administration.'Regular monitoring and feedback occurs between teams to establish achievement of collaborative goals'.Theoretically, the suggestion is that regular monitoring and feedback of the performance of the collaboration is critical for continuous improvement (Frey et al., 2006;Gajda, 2004;Peterson, 1991).• Factor: autonomy.'I can commit to collaborative endeavours, without first getting approval'.Empowerment of individuals representing their groups helps in facilitating more timeous decisions (Thomson et al., 2007).The empowerment concept was added in two items, related to the initial commitment to the collaboration and decisionmaking during the collaboration, as illustrated in the next point (8).• Factor: autonomy.'As team member I am aware of what decisions I am mandated to make in collaborative endeavours'.• Factor: mutuality.'Other teams share knowledge with my team that strengthens our operation'.The original scale contained the item 'My team shares knowledge with other teams that strengthens their operation'.This was retained, but it was considered important to include a question testing reciprocity on knowledge sharing.• Factor: mutuality.'The individuals in other teams put the collective interests of collaboration above their individual interests'.This concept is cited as a key success factor for successful collaboration in the literature (Hudson et al., 1999;Mattessich et al., 2001;Srivastava & Banaji, 2011;Tsasis, 2009) The Trust in Teams Scale (Adams et al., 2008) was applied to test convergent validity with the norms factor of the Thomson, Perry and Miller Collaboration Instrument (Thomson et al., 2007).The Trust in Teams Scale (Adams et al., 2008) was designed to measure four dimensions of trust, namely, competence, integrity, benevolence and predictability.The scale was originally designed for testing in a military context but the items are generic and hence applicable to any team.The questionnaire consists of 20 items with a seven-point Likert scale ranging from completely disagree to completely agree.The Trust in Teams Scale (Adams et al., 2008) performed with Cronbach's alpha ranges from 0.89 to 0.95.CFAs confirmed the construct validity of the four-factor model, though indices were not provided by the authors (Adams et al., 2008).For the purpose of consistency with the Thomson, Perry and Miller Collaboration Instrument (Thomson et al., 2007), the scale was re-worded to 'strongly' disagree and 'strongly' agree.Because trust can be considered a socially desirable concept (Adams et al., 2008), it was not explicitly stated in the overview to participants as a measurement dimension.

Research procedure
The revised version of the Thomson, Perry and Miller Collaboration Instrument (Thomson et al., 2007) was distributed to a pilot group of eight professionals in organisations for feedback on face validity.They were requested to provide feedback as to whether they had any difficulties in understanding the questions and agreed with the wording and representativeness of the items on identified factors.Feedback was received from six people.Minor appropriate adjustments were made to the questionnaire and resent to this group.The second round of feedback resulted in no additional changes to the questionnaire.Two survey software programs were investigated for their suitability for data collection, namely, Survey Monkey (n.d.) and Question Pro (n.d.).The survey was loaded onto both platforms and test data were inputted.Question Pro was selected for its capability to customise, filter and export the data most efficiently.A senior member in each organisation compiled an email with a brief note encouraging staff participation in the survey.Participants were requested to respond to the questionnaire within 2 weeks.An email reminder was sent after week one.

Statistical analysis
Exploratory Factor Analysis and CFA was conducted to test for construct validity, in order to indicate how well the instrument aligns to the theoretical assumptions on collaboration.Exploratory Factor Analyses explored possible alternative factor structures with no constraints on variable loading (Blumberg, Cooper & Schindler, 2008).This was followed by Principal Factor Analysis with Varimax Rotation.Cronbach's alpha was used to test for reliability for each of the five factors (Sekaran & Bougie, 2013).This was to test for items that have strong relationship with each other and the relative factors of collaboration.CFA examined the fit of the adjusted theoretical model through specifying which items define each factor (Blumberg et al., 2008).The Trust in Teams Scale (Adams et al., 2008) was applied to test convergent validity with the norms factor of the Thomson, Perry and Miller Collaboration Instrument (Thomson et al., 2007).

Results
Descriptive statistics for the items in the Revised Thomson, Perry and Miller (2007) Collaboration Instrument show that all items received the minimum and maximum responses on the Likert scale.The mean ranged from 2.63 to 5.92 with standard deviations ranging from 1.220 to 1.648.All items in the Trust in Teams Scale (Adams et al., 2008) Thomson, Perry and Miller (2007) Collaboration Instrument on a four-factor model is reported in Table 2.
Exploratory Factor Analysis of the Trust in Teams Scale (Adams et al., 2008) indicated the KMO measure (KMO) above 0.6, at an acceptable level of 0.96.The Bartlett's test of sphericity was at a significant level Chi-square = 9064.85(df = 171; p = 0.000).Two factors with Eigenvalues were above one, explaining 78.3% of the total variance.The two components of the Trust in Teams Scale (Adams et al., 2008) were named Component 1: integrity and Component 2: competence.
The CFA was done by means of EQS.The CFA of both the Revised Thomson, Perry and Miller (2007) Collaboration Instrument and the Trust in Teams Scale (Adams et al., 2008) are reported in Table 3. Items that cross loaded and were initially omitted though did not increase fit indices.
http://www.sajhrm.co.zaOpen Access   This could be due to similarity of questions.The final factors thus included the cross loading items.None of the Mardia's coefficients were less than three, which is an indication of a significant non-normality.Chi-square indices of the different factors showed a weak to good fit with the data.Weak fits are indicated in governance, integrity and competence.Collaboration total has a good fit of 4.3.Trust in Teams total has a weak fit of 10.01.Comparative fit indices are between 0.86 and 0.99, which is between a reasonable and good fit (Hair, Black, Babin, Anderson & Tatham, 2006).No CFA was performed on autonomy as there were only three items.

Convergent validity
Convergent validity of only the norms factor of the Revised Thomson, Perry and Miller (2007) Collaboration Instrument was tested in relation to the Trust in Teams Scale (Adams et al., 2008) by means of structural equations modelling.This is illustrated in Figure 2.
CFA of the Structural Equation Model in Figure 1 shows significant path coefficients at the 5% level of confidence.Goodness of fit indices showed a moderate fit with the data with Bentler-Bonnett normed fit index = 0.84, comparative fit index (CFI) = 0.85, Bollen's fit index = 0.85, and RMSEA = 0.15 within the 90% confidence interval of 0.14 and 0.15.

Discussion
The results of this study provide acceptable indices of the Revised Thomson, Perry and Miller (2007) Collaboration Instrument when applied to a South African sample.It affirms the premise by Foxcroft and Roodt (2005) that instruments used in alternative countries must be validated for a South African context.It addresses the recommendations of Thomson et al. (2007) to refine their scale with the addition of items and subsequent testing of construct validity in other contexts.
Thirteen of the fourteen new items were retained.Only two items in total were eliminated, both which loaded on factor five in the initial Principal Components Analysis.These items were eliminated as they could not be theoretically explained.
The moderate convergent validity with the prediction of norms on the trust factors of integrity and competence could be due to the different reference to team collaboration of the two instruments.The Revised Thomson, Perry and Miller (2007)   are competent'.The Trust in in Teams Scale (Adams et al., 2008) makes reference to participants' experience of own teammates, for example, 'My teammates are capable at their jobs'.
Linking findings to the literature  2007) model (Kaats & Opheij, 2014;Mattessich et al., 2001;Oziewicz, 2007;Patel et al., 2012).Theoretically, these components could be considered part of governance and hence in this study were interpreted as one factor.
The four-factor model is well supported by the literature.The factor of governance (including administration) measures the creation and implementation of rules and structures that govern the collaboration.This supports the assertion that establishing structural processes, work standards, methods and frameworks to guide collaborative relationships is important (Campbell, 2006;Kaats & Opheij, 2014;Patel et al., 2012;Sanchez, 2012;Thomson et al., 2007).This factor also encompasses the notion that clear goals, roles, policy guidelines and communication channels are important components in collaboration as identified by various authors (Kaats & Opheij, 2014;Mattessich et al., 2001;Patel et al., 2012;Petri, 2010;Quicke, 2000;Sanchez, 2012).
The factor of mutuality is supported by the concept that mutual dependence provides the most suitable conditions for collaboration (Henneman, Lee & Cohen, 1995;Petri, 2010).Furthermore, perceived mutually beneficial outcomes are cited as important in collaborative endeavours (Campbell, 2006;Ofori & Sackey, 2010;Pastoriza, Arin & Ricart, 2009;Wollebaek & Selle, 2007).Managing conflict is a component of the mutuality factor which is supported by Gajda (2004) who proposed that conflict can even be constructive, however proper management thereof is important.
The factor of norms is underpinned by the perceptions of individuals that collaborative partners can be trusted.
This supports the assertion that trust plays a key role in collaborative relationships (Kaats & Opheij, 2014;Mattessich et al., 2001;Patel et al., 2012;Thomson et al., 2007).Both affective and cognitive trust elements (Johnson & Grayson, 2005) are represented in the items.Cognitive trust relates to the perception that the other party is capable and likely to deliver on their commitments.Affective trust is based on positive relational experiences.
The factor of autonomy refers to the tension between the collective interests of all parties and the self-interest of groups (Thomson et al., 2007).Hudson et al. (1999) supported the existence of this tension through encouraging collaborative parties to recognise where interdependence is appropriate and respect where independence is warranted.Tsasis (2009) also proposed that a balance between autonomy and dependence is required for effective collaboration.

Implications for practice
The Revised Thomson, Perry and Miller (2007) Collaboration Instrument provides a measure for leaders and HR practitioners to explore the status of collaboration in organisations and across organisations in South Africa.
The results could provide HR practitioners information that helps them to identify opportunities for leadership development, knowledge sharing, inter-team effectiveness and bottom-up collaboration.This could help to promote the positioning of the human resource function as a strategic business partner.The theoretical model alone can be used by organisations as a conversational framework to explore perceptions on collaboration in different contexts.The results of a collaboration assessment could suggest courses of action for leaders to address obstacles and challenges associated with collaboration such as varying priorities, conflicts and territory issues (Sanchez, 2012) and create mechanisms to mitigate these.This should enable organisations to leverage the benefits of effective collaboration.

Limitations of the study and implications for future research
Although the study shows the four-factor Revised Thomson et al. (2007) to be valid for a South African sample, various limitations should be considered.This study was done only in two organisations in South Africa, in two industries, information technology and industrial services.A larger variety of organisations and other countries should be considered in future research.The sample obtained was predominantly English and Afrikaans speaking (87.5%), with a small percentage representing the remaining nine official languages of South Africa.Future studies should aim to acquire a more South African demographically representative sample.
Cross-loadings of items indicate a lack of variety between questions, especially in the case of governance and administration.Future measure of this instrument should phrase items to show more variety between questions.Specifically, the governance and administration items should be phrased in a manner that would make a clearer distinction between these two factors.
Future studies on convergent validity of the norms factor of the Thomson, Perry and Miller Collaboration Instrument (Thomson et al., 2007) and trust instruments should phrase participants' team experience and observation in a similar fashion to address the moderate results of the convergent validity.
This study has only examined the validity of one instrument in a South African context.Subsequent to completion of this research, an article by Marek et al. (2015) was published.The authors developed and validated a Collaboration Assessment Tool for use in a general business context.Internal consistency of the instrument was 0.97.CFA fits were at an acceptable level: RMSEA = 0.06.It is evident that this instrument would have also been suitable for validation for the South African context had it been published prior to the planning of this study.Future research could therefore focus on validation of other appropriate instruments for South Africa.
A beneficial future research focus would be to conduct longitudinal studies to explore the impact of time and other contextual changes on collaboration processes.Longitudinal studies could also further test the premise that collaboration occurs in a series of stages (Frey et al., 2006;Gajda, 2004;Peterson, 1991).

Conclusion
This research demonstrated the importance of collaboration between and within organisations.South African businesses face many external and internal challenges that necessitate the optimal use of resources for increased efficiency and innovation.It is evident that this can be achieved through collaborative partnerships.If South African leaders are to leverage the benefits of their workforce through collaboration, they require insight into the status of collaboration in order to initiate change.As far as could be ascertained, there is no evidence of a measurement instrument to provide this insight in South Africa.Organisations place themselves at risk when using an instrument developed in another country and not tested for use with their specific population.The Revised Thomson, Perry and Miller Collaboration Instrument addresses the need for a collaboration instrument validated for a South African sample.In conclusion, this study contributes to the understanding of collaboration and how to maximise its practical benefits.
