The primary research objective is to investigate how project management and organizational behavior frameworks can be used to evaluate and enhance the performance and growth of key suppliers within the South African defense sector. The research seeks to address the gap in supplier knowledge by implementing standardized performance measurement and assessing supplier readiness for Just-in-Time (JIT) integration.
1.1 INTRODUCTION
To sustain growth and performance at suppliers from a project management approach has a numerous impact to any organisation that want to measure performance to set a benchmark for stakeholders that will generate profit on a long-term basis. Increasing customer demands for quality products have forced organisations to adopt quality philosophy of TQM (Total Quality Management) and SRM (Supplier Relationship Management) in every aspect of the business. Research literature normally contributes performance contributing by forecasting (Mentzer and Bienstock, 1989; Chase, 1999). In implies that when forecast accuracy increases, cost and performance consequently improves with a correlated forecasting error. Due to dynamic technological, political and variable economic changes in world and in particular South Africa a dearth of performance and growth in key and general suppliers have been experienced owing to late deliveries concerning the products manufactured, the quality and service provided by the suppliers that influence and terminate important business in the defence industry we contribute as world class customers.
Validating key suppliers at company X where the author is currently working was taken on monthly intervals on data provided by quality departments, also treated to be confidential data and these data were compiled and summarised for the year. It presented information that lead to this thesis to be formulated finding why suppliers especially key suppliers performance do not increase. Behind the normal philosophy to evaluate quality, price, delivery and services suppliers provide measuring their performance the argument leading to the thesis also pertains to a hypothetical question i.e. “what do we know about the our supplier?”. The knowledge about the suppliers itself remains unknown if we cannot measure the internal affairs of the suppliers itself leading to performance and growth making supply chain successful.
CHAPTER 1: INTRODUCTION AND BACKGROUND: This chapter provides an overview of the research scope, defines the problem regarding supplier performance, and outlines the primary and sub-investigative research questions.
CHAPTER 2: LITERATURE REVIEW: This chapter examines theoretical foundations regarding performance management, Supplier Relationship Management (SRM), organizational behavior, and quality philosophies like TQM and JIT.
CHAPTER 3: RESEARCH DESIGN AND METHODOLOGY: This chapter details the research methodology, including the development of the Supplier Performance Questionnaire (SPQ) and the Supplier Quality Questionnaire (SQQ) used to gather empirical data.
CHAPTER 4: DATA ANALYSIS: This chapter presents the statistical analysis of the survey responses from 16 key suppliers, mapping them against the defined research dimensions and JIT readiness.
CHAPTER 5: CONCLUSIONS AND RECOMMENDATIONS: This chapter summarizes the research findings, concludes on the performance and JIT maturity of the suppliers, and offers recommendations for future supplier development.

The research focuses on utilizing a project management approach to evaluate and improve the performance of key suppliers, specifically within the context of the South African defense sector.
The study centers on Supplier Relationship Management (SRM), organizational behavior, quality control systems, leadership dynamics, and the implementation of Just-in-Time (JIT) methodologies.
The primary goal is to analyze the performance gap in supplier behavior to identify strategic tools that can sustain growth and operational efficiency through better organizational understanding.
The research utilized a quantitative and qualitative approach, conducting in-depth surveys of 16 key suppliers using standardized questionnaires (SPQ and SQQ) and performing statistical reliability analysis via Cronbach’s Alpha.
The body covers an extensive literature review of management frameworks, the design and validation of research instruments, detailed empirical analysis of supplier data, and a final synthesis of conclusions.
Keywords include Supply Chain Management, Organizational Behavior, Just-in-Time, Supplier Relationship Management, and Defense Industry performance metrics.
The research finds that JIT maturity directly influences a supplier's ability to integrate into a pull-system, which is critical for reducing waste and meeting the specific complex requirements of the defense industry.
The findings indicate that while suppliers show motivation and commitment, there is a significant need for better integration, leadership training, and cultural alignment to bridge existing performance gaps.
The Performance Matrix serves as a diagnostic framework to map individual and group mechanisms, such as stress, motivation, and leadership skills, against final business outcomes like job performance and commitment.
