TMMi

TMMi (Testing Maturity Model integrated) is a framework for evaluating and improving software testing processes. It provides a structured, evidence-based approach for organizations to assess the maturity of their testing practices and to plan deliberate improvements. The model is vendor-neutral and independent from specific development methods.

TMMi defines five maturity levels, progressing from initial through managed, defined, measured, and optimizing. Each level is associated with a set of key process areas and specific goals and practices that organizations should satisfy to advance. The emphasis is on establishing repeatable processes, proper planning, structured test design and execution, defect management, test environment and data management, and measurement of testing performance.

Assessment and certification: Organizations perform formal assessments against the TMMi model. Trained assessors review evidence from projects and processes to determine a maturity rating and an improvement roadmap. The TMMi Foundation governs the model, coordinates training, maintains the standard, and certifies assessors and training providers.

Purpose and use: TMMi is used by software development and testing teams, QA departments, and outsourcing providers to benchmark current practice, compare with peers, and guide process improvement programs. It is often used in procurement and supplier management to specify testing capability requirements.

History and scope: The model originated from international collaboration under the auspices of the TMMi Foundation and related industry and academic partners. It is designed to be aligned with other process improvement frameworks and to support continual improvement in testing maturity across various domains, project sizes, and development methods.
