This paper focuses on incorporating Structural Quality Metrics derived from static code analysis into outsourcing Service Level Agreements (SLAs) to build a transparent and healthy relationship with the service providers, while maintaining visibility and control over the outsourced applications to mitigate any potential risks. Content of the document may be used to build a technical addendum as part of a Master Agreement “Software Quality of Deliverables” or “Acceptance Criteria” section.

Software Structural Quality Metrics For SLAs

Companies have historically made services providers account- able for the quality of delivered products and services, primarily by incorporating metrics on project quality (schedule adherence, change management, etc.) and process quality (methodologies) into their SLAs. While it might seem obvious to hold outsourced teams accountable for the intrinsic quality of the product itself, this measure has typically been ignored in SLAs, primarily due to the lack of effective tools to measure product quality in a comprehensive way.

Static code analysis enables au- tomated, continual and objective assessment of the structural quality of applications being de- livered from service providers.
There are primarily three cat- egories of outputs, representing a combination of higher-level and lower-level structural quality metrics of software that can be incorporated into SLAs to achieve a specific business need or objec- tive: Quality Indices, Application- Specific Rules and Productivity.

Quality Indices

Static code analysis solutions parse source code and identify code patterns (rules) that could lead to potential defects. By cat- egorizing these improper code patterns into application health factors such as Security, Performance, Robustness, Changeability and Transferability, you can aggregate the results and assign a specific value to each category. Figure 1 provides an example of how rules can be aggregated to form meaningful metrics.
Ideally, you should analyze your applications for a minimum of two to three releases and use the average scores as a baseline for each of these health factors. You can then set targets to monitor the overall health of the application over time.
