Discover the critical role of Supplier Agreement Management (SAM) in CMMI Level 2 for effective software acquisition and quality assurance. Learn how integrating non-technical features catalogues can streamline supplier evaluation, minimize risks, and optimize project outcomes.
In today’s rapidly evolving software development landscape, quality assurance and process improvement are more critical than ever. Organizations are increasingly adopting frameworks like Capability Maturity Model Integration (CMMI) to enhance their software processes, ensure better quality, and manage risks effectively. Among the various process areas (PAs) defined in CMMI Level 2, Supplier Agreement Management (SAM) plays a pivotal role in overseeing relationships with suppliers, especially when dealing with Commercial-Off-The-Shelf (COTS) products or outsourced software components.
This post delves into the SAM process area within CMMI Level 2, emphasizing its significance, challenges, and best practices. We will explore the integration of non-technical features catalogues to streamline supplier management, as discussed in the study by Carvallo et al., and analyze a real-world case study involving ETAPATELECOM, a telecommunications company in Ecuador.
CMMI (Capability Maturity Model Integration) is a process-level improvement training and appraisal program administered by the CMMI Institute. CMMI is structured into five maturity levels, each of which groups a set of predefined process areas that are critical for software engineering and development practices. These levels range from Level 1 (Initial) to Level 5 (Optimizing), indicating the organization’s maturity in handling software projects effectively.
CMMI Level 2, known as the „Managed” level, focuses on establishing basic project management practices. Organizations at this level are characterized by their ability to repeat successful processes across similar projects, ensuring that successful practices are retained even in stressful situations.
SAM is a key process area in CMMI Level 2, specifically designed to manage the acquisition of products and services from suppliers. This area addresses the complete lifecycle of supplier management, from selecting suppliers, establishing agreements, to overseeing the execution and ensuring compliance with the terms of the agreement. The primary goals of SAM include:
Establishing Supplier Agreements: Ensuring that all supplier-related agreements are well-documented, comprehensive, and in alignment with the organization’s requirements and project objectives.
Satisfying Supplier Agreements: Monitoring and managing supplier performance to ensure that all contractual obligations are met, and the acquired products or services meet the expected quality and functionality.
The SAM process area is crucial when dealing with COTS products or outsourced software components, as it mitigates risks associated with supplier reliability, product quality, and compliance.
As of 2022, over 10,000 organizations worldwide have adopted CMMI models, highlighting its role as a leading framework for process improvement and capability development across various industries.

While the technical quality of software products is often emphasized, non-technical features play a significant role in the success of supplier management. Non-technical features include aspects such as cost, licensing, support services, supplier reputation, and risk management, which are not directly related to the software’s intrinsic quality but significantly impact the overall project outcome.
The study by Carvallo et al. highlights the importance of integrating non-technical features catalogues to support CMMI Level 2 SAM practices. These catalogues provide a structured approach to defining, categorizing, and evaluating non-technical aspects, ensuring a comprehensive analysis during supplier selection and management.
Carvallo et al. proposed a method for constructing a non-technical features catalogue tailored to CMMI Level 2 SAM requirements. The development process involves the following steps:
Defining Characteristics and Subcharacteristics: The catalogue starts by identifying high-level non-technical characteristics (e.g., supplier reputation, cost management) and breaks them down into more specific subcharacteristics.
Customizing the Catalogue: Organizations can customize the catalogue based on their specific needs, project context, and industry standards. This customization ensures relevance and applicability to the particular software acquisition scenario.
Using Metrics for Evaluation: Each non-technical feature is associated with specific metrics that facilitate quantitative evaluation. These metrics provide a uniform way of comparing different suppliers and products, aiding decision-making.
