Horizontal traceability

Horizontal traceability shows relationship among related items such as between requirements itself. It traces dependent items within a development phase. Vertical traceability is a characteristic identifying the source of requirements typically from requirements to design, to the source code and to test cases. Horizontal traceability is an aspect identifying non hierarchical similarities, mutual properties, interactions, […]

Customer Needs to Derived Requirements

Requirements are the basis for design. Requirements management processes manage all requirements received or generated by the project, including both technical and nontechnical requirements as well as requirements levied on the project by the organization. In CMMI Requirements Management (REQM) Process Area provides traceability of requirements from customer requirements to product requirements to product component […]

How to set objectives if there is no baseline?

Baselines are created for the core “value-generating” processes of the business in the organizations. From the observed measurement data, an organization comes up with various process performance baselines (PPB) periodically. In a software industry, there can be PPBs for coding speed, defect density, productivity, testing speed, review effectiveness etc. Then measurable improvement targets (process performance […]

Statistical Tests in Minitab leading to CMMI High Maturity

In this article, 7 statistical tests are explained which are essential for doing statistical analysis inside a CMMI High Maturity (HM) compliant project or organization. 1       Stability test Definition: Data stability for the selected parameter is tested using minitab before making performance baselines. Steps: Go to Stat->Control Charts-> I-MR (In variables, enter the column containing […]

Equivalent staging in CMMI

CMMI appraisal method is known as SCAMPI. Result of appraisal may include a rating as demanded by the appraisal sponsor. In a continuous representation Rating is a “capability level profile” (e.g. Requirements Development Process Area is at Capability level 3). In a staged representation Rating is a “maturity level rating” (e.g. maturity level 2). Maturity […]

Evolutionary Path of Process Areas in CMMI

In CMMI, have you noticed the evolutionary path for Process Areas? Infact CMMI Maturity Levels are defined as evolutionary stages of process improvement. An evolutionary process is a process whose stages consist of expanding increments of the defined process. Watts Humphrey’s Capability Maturity Model (CMM) was published in 1988. According to him organizations mature their […]

Configuration Baseline and Performance Baseline

“Walking on water and developing software from a specification are easy if both are frozen.” –  Edward Berard Baseline means ‘A Line which is the Base’. The word baseline may refer to surveying, typography, budgeting, pharmacology, Configuration Management, calculations etc. In an IT industry, baseline mainly implies A Configuration Baseline – A configuration of software, […]

CMMI NextGen

CMMI Version 1.3 was released on November 1, 2010. All the three constellations of CMMI – SVC, ACQ and Dev, got released in the same period, considering the similarities across them. How good it would be, if all the three constellations were combined into a single model..? Definitely it would have eased the process of […]

Quantitative management of CAR

Causal Analysis and Resolution (CAR) helps to identify and rectify the root cause of a defect or problem. It can be applied to any process area. Analysis can be qualitative, limited to a fish bone diagram or so. And at the same time it can be more advanced involving quantitative data. The steps below show […]

Requirements Traceability

Traceability is the ability to trace the origin. In simple terms a police man identifies thieves by tracing out finger prints or so.. Traceability plays a key role in Requirements Management. It helps to conduct impact assessments when change in requirements happens.  Some unique identifiers are given for each requirement. These requirements are elaborated from […]
