The project consisted of members of industry, government and the Carnegie Mellon Software Engineering Institute (SEI). The main sponsors included the Office of the Secretary of Defense and the National Defense Industrial Association. CMMI is the successor of the capability maturity model (CMM) or Software CMM. The CMM was developed from 1987 ...
The Capability Maturity Model was originally developed as a tool for objectively assessing the ability of government contractors' processes to implement a contracted software project. The model is based on the process maturity framework first described in IEEE Software [2] and, later, in the 1989 book Managing the Software Process by Watts ...
ISO/IEC 15504 is the reference model for the maturity models (consisting of capability levels which in turn consist of the process attributes and further consist of generic practices) against which the assessors can place the evidence that they collect during their assessment, so that the assessors can give an overall determination of the organization's capabilities for delivering products ...
Maturity Models specific to software evolution have been developed to improve processes, and help to ensure continuous rejuvenation of the software as it evolves iteratively [citation needed]. The "global process" that is made by the many stakeholders (e.g. developers, users, their managers) has many feedback loops.
The suite of documents associated with a particular version of the CMMI includes a requirements specification called the Appraisal Requirements for CMMI (ARC), [2] which specifies three levels of formality for appraisals: Class A, B, and C. Formal (Class A) SCAMPIs are conducted by SEI-authorized Lead Appraisers who use the SCAMPI A Method Definition Document (MDD) [3] to conduct the appraisals.
The term performance engineering encompasses more than just the software and supporting infrastructure, and as such the term performance engineering is preferable from a macro view. Adherence to the non-functional requirements is also validated post-deployment by monitoring the production systems.
The implementation maturity model (IMM) is an instrument to help an organization in assessing and determining the degree of maturity of its implementation processes. This model consists of two important components, namely the: five maturity levels, adopted from capability maturity model (CMM) of the Software Engineering Institute (SEI).
The models have two basic types - prediction modeling and estimation modeling. 1.0 Overview of Software Reliability Prediction Models. These models are derived from actual historical data from real software projects. The user answers a list of questions which calibrate the historical data to yield a software reliability prediction.
