CMMI

Overview

CMMI is the acronym for Capability Maturity Model Integration. It is a framework used in project management, which helps to improve software development processes. The framework was developed for the Department of Defense by the Software Engineering Institute for Software Development and published in 1991 (cf. http://www.enzyklopaedie-der-wirtschaftsinformatik.de/lexikon/is-management/Systementwicklung/reifegradmodelle/cmmi 19.04.17). Best-practices and maturity-level shall either support the enterprise's management or measure the compliance according to the framework. The two aspects are on the one hand mandatory to redefine processes for saving costs and deliver on time. On the other hand, CMMI supports a categorisation of conformity by comparing established modules from the CMMI-framework with the actual business. Reorganisation, prioritisation and monitoring for activities regarding team, division and the whole business are essential for the framework (cf. http://cmmiinstitute.com/about-cmmi-institute 19.04.17).

There are three subject-orientated models (http://www.sei.cmu.edu/library/assets/cmmi-overview071.pdf p.17 19.04.17):

  1. Development of Software Products and Services
  2. Acquisition of Products and Services
  3. Establishment, management and delivery of services

Business Objectives

Dennis M. Ahern states seven main business objectives (http://www.informit.com/articles/article.aspx?p=169102 19.04.17).These aspects are focused on the business objectives in a company and can fulfill the management’s needs.

  1. Produce quality products or services
  2. Create value for the stockholders
  3. Be an employer of choice
  4. Enhance customer satisfaction
  5. Increase market share
  6. Implement cost savings and best practices
  7. Gain an industry-wide recognition for excellence

Structure

There are two different ways of the application in terms of CMMI. The first one is the Maturity Level, which help to locate processes in terms of conformity. The second one is categorisation of the processes. The following listing specifies the structure in detail (http://dqsindia.com/cmmi/getting-started/ 20.04.17).

1. The maturity level is defining the progress of the framework’s application. They are separated in five different categories. Key process areas are allocated to these.

Manurity Level 1 – initial

  • Here no level is implemented in the enterprise

Manurity Level 2 – managed

  • Configuration Management
  • Measurement and Analysis
  • Project Monitoring and Control
  • Project Planning
  • Process and Product Quality Assurance
  • Requirements Management
  • Supplier Agreement Management

Manurity Level 3 – defined

  • Decision Analysis and Resolution
  • Integrated Project Management
  • Organizational Process Definition
  • Organizational Training
  • Organizational Process Focus
  • Product Integration
  • Requirements Development
  • Risk Management
  • Technical Solution
  • Validation
  • Verification

Manurity Level 4 – quanitativley managed

  • Organizational Process Performance
  • Quantitative Project Management

Manurity Level 5 – optimizing

  • Causal Analysis and Resolution
  • Organizational Performance Management

Categories are separated in a listing way of order

1. Project Management

  • Integrated Project Management (IPM)
  • Project Monitoring and Control (PMC)
  • Project Planning (PP)
  • Quantitative Project Management (QPM)
  • Requirements Management (REQM)
  • Risk Management (RSKM)
  • Supplier Agreement Management (SAM)

2. Engineering

  • Product Integration (PI)
  • Requirements Development (RD)
  • Technical Solution (TS)
  • Validation (VAL)
  • Verification (VER)

3. Process Management

  • Organisational Performance Management (OPM)
  • Organisational Process Definition (OPD)
  • Organisational Process Focus (OPF)
  • Organisational Process Performance (OPP)
  • Organisational Training (OT)

4. Support

  • Causal Analysis and Resolution (CAR)
  • Configuration Management (CM)
  • Decision Analysis and Resolution (DAR)
  • Measurement and Analysis (MA)
  • Process and Product Quality Assurance (PPQA)

Advantages

Project management is often more responsible for end-success than technical obstacles. Therefore, CMMI is a good best practice framework for organising and managing work. Besides, maturity level is often used for benchmarking capabilities in enterprises. To get a request from the Department of Defense, a company must have a maturity level of minimum 3. CMMI defines standards and alleviates comparison between software developing companies (cf. http://www.cmmiconsultantblog.com/cmmi-faqs/advantages-and-disadvantages-of-cmmi-dev-for-a-software-development-it-organization-and-how-to-overcome-these-disadvantages/ 20.04.17).

Disadvantages

Although CMMI includes just a framework and not a strict standard Software Development Lifecycle (SDLC), it is often described as to bureaucratic. Especially focusing on documentation of processes for improvement can harm agile methods. Moreover, the maturity level can innovations because organisations don’t want to lose their status (cf. http://www.cmmiconsultantblog.com/cmmi-faqs/advantages-and-disadvantages-of-cmmi-dev-for-a-software-development 20.04.17).

Usage in Data Vault

In terms of data warehouse, the CMMI framework provides an organizational structure for team building and collaborative working on a reliable basis. The structure of a data warehouse based on data vault must be full auditable and stable. Therefore, the use of CMMI can be helpful because it eliminates unnecessary activities in all development processes.
