SEI CMMI Models Disciplines - SEI Capability Maturity Model Implementation (SEI CMMI)

What are SEI CMMI Models Disciplines?

The CMMI is a model that has integrated many bodies/ disciplines of knowledge. Presently there are 4 bodies of knowledge feasible to you while selecting a Capability Maturity Model Integration.

Systems Engineering

Systems engineering will cover the development of entire systems, that may or may not involve software. Systems engineers targets on transforming customer expectations, needs and constraints into product solutions and supporting these product solutions in the entire life cycle of the product.

Software Engineering

Software engineering will cover the development of software systems. Software engineers targets on the application of disciplined, quantifiable and systematic paths to the development, operation, and maintenance of a particular software.

Integrated Product and Process Development

Integrated Product and Process Development (IPPD) is a systematic method that accomplishing a timely collaboration of relevant stakeholders all through the life of the product for better satisfaction of customer needs, requirements expectations. The processes to support an IPPD method are combined with the other processes in the organization.

If an organization or project selects IPPD, it executes the IPPD best processes simultaneously with other best processes employed to produce products (e.g., those related to systems engineering). This means, if an project or organization wants to employ IPPD, it should choose one or more disciplines together with IPPD.

Supplier Sourcing

As task efforts became more difficult, project managers may employ suppliers to execute functions or add alterations to existing products that are especially required by the project. When those activities are critical, the project will get benefited from improved source analysis and from supervising supplier activities in prior to product delivery. In these situations, the supplier sourcing discipline will cover the winning of products from suppliers.

Likewise to IPPD best methods, supplier sourcing best methods should be choosen in combination with best methods employed to procure products.

CMMI Discipline Selection

Choosing a discipline may be a complex step and rely on what an organization wishes to improve.

  • Enhance you are upgrading your systems engineering processes, like Measurement and Analysis, Configuration Management, Organizational Process Focus, Process and Product Quality Assurance, Project Monitoring and Control, Supplier Agreement Management, Risk Management etc., then you must choose Systems engineering (SE) discipline. The discipline amplifications for systems engineering receive a great emphasis.
  • If you are improving your integrated product and process development processes like Integrated Teaming, Organizational Environment for Integration, then you should select IPPD. The discipline always targets for IPPD gain special attention.
  • If you are enhancing your source choosing processes like Integrated Supplier Management then you must choose Supplier sourcing (SS). The discipline always targets for supplier sourcing gain special attention.
  • If you are enhancing multiple disciplines, then you require to work on all the areas regarding to those disciplines and pay consideration to all of the discipline developments for those disciplines.

We will discuss various areas regarding CMMI implementation in upcoming chapters.
