Research & validation

Evidence that the model holds.

Super-Cube® was developed and tested through a pragmatic explanatory sequential mixed-methods design—quantitative structure first, qualitative depth second—within an African FMCG business-network, and published in peer-reviewed journals.

Title: A Leadership Skills Development Model for the Kwaden Group: A Case Study of an African FMCG Business-Network (Muller, C. R., 2020, University of KwaZulu-Natal, Doctor of Business Administration).

Leadership capacity in emerging-market business networks is constrained by complexity, skills gaps, and imported models that under-weight whole-person development. This research developed and validated a six-construct cubic model—Choices, Principles, Mental, Emotional, Physical, Spiritual—with the individual at the centre.

Mixed methods: survey (N=132) with confirmatory factor analysis (acceptable fit, CFI≈0.86; scale reliability α≈0.60–0.80) and senior-leader interviews (N=10) for thematic validation. Philosophy of mutual respect (Buber’s I–Thou) informs practice design.

Implication: leadership is substantially developable; measurement before and after deliberate practice is the product. Super-Cube® Learn operationalises that loop for kids, adolescents, and adults.

Peer-reviewed outputs (2022) appear in the South African Journal of Economic and Management Sciences (SAJEMS) and the Journal of Contemporary Management (JCM)—see Journal articles below for open PDF downloads and DOI links.

The Theory-level literature map moves from classical trait/behavioural/contingency schools through relational, shared, biological/evolutionary and neuroscientific perspectives, into contemporary topics (identity, culture, globalisation, entrepreneurial leadership), skills-development debates, and higher-order frames—AQAL, I–Thou, and Ubuntu—which collectively underpin the six-dimensional model.

Case-study account of applying and validating the leadership skills development model within the Kwaden Group African FMCG network.

Methodology

Pragmatic. Sequential. Practice-oriented.

The research prioritised practical utility and real-world applicability—testing whether the six-construct structure fits observed leadership reality.

Mixed-methods design

Pragmatic explanatory sequential design: quantitative survey first, then qualitative interviews to explain and deepen the findings.

132 survey respondents

Online survey of Kwaden Group employees tested structural validity and reliability across the six constructs.

Acceptable model fit

Confirmatory factor analysis: CMIN/DF 2.232, CFI 0.86, RMSEA 0.097—collectively indicating acceptable structural fit.

10 senior interviews

Thematic analysis of decision-maker interviews validated all six constructs in lived leadership practice.

Intervention outcomes

Measurable growth across every face.

Structural validation

Acceptable model fit. Adequate reliability.

Internal consistency across constructs

Fit indices collectively suggest acceptable model fit based on established thresholds in structural equation modelling. Reliability coefficients indicate adequate to good internal consistency for the study sample.

Qualitative findings

What senior leaders emphasised.

Face-to-face semi-structured interviews with 10 key decision-makers (Nov 2018–Feb 2019) were analysed using inductive thematic analysis (Braun & Clarke).

Mental
31%
Emotional
29%
Principles
18%
Spiritual
12%
Choices
9%
Physical
1%

Mental (31%) and Emotional (29%) together accounted for roughly 60% of construct-related qualitative content—underscoring cognitive and relational demands in practice. Principles (18%), Spiritual (12%), Choices (9%), and Physical (1%) also appeared as meaningful themes.

Participants expressed unanimous support for multilevel leadership development—from individual to organisational and network levels—with recommendations for inclusive approaches that can extend to suppliers and customers for a broader ripple effect.

Limitations

Honest about scope.

The model was developed and validated within a single-case study of one African FMCG business-network. Findings are context-specific and should not be over-generalised without further testing.

Wider industry replication—across organisations, regions, and sectors facing comparable challenges—is recommended to assess robustness and refine the six constructs for broader continental and emerging-market use.

Significance

Africa-centric and practice-ready.

Super-Cube® stands as one of the first empirically validated leadership development frameworks tailored to African FMCG complexity—bridging Western-dominant theory and local organisational reality.

By emphasising human-centric constructs and the developable nature of leadership (estimated at 70–76% through practice), it offers a credible, context-sensitive alternative for organisations building capacity at scale.
