Cmmi Levels

Software Engineering is a discipline focused on the development and maintenance of software projects, emphasizing quality, schedule, and budget. Key aspects include the importance of reusability to enhance productivity and reduce costs, as well as the necessity of following a structured software process to avoid issues like late delivery and quality problems. The Capability Maturity Model Integration (CMMI) provides a framework for assessing and improving software development processes across five maturity levels.

Software Engineering

 Software Engineering is technological & managerial both discipline concerned on a development


& maintenance of a software project are products on time within cost estimation.
 There are three important factors in software development is:
o Quality
o Schedule/time
o Budget/Cost
 Developing a quality software within budget and within cycle time.
 One of the important characteristics of software engineering is ‘Reusability’.
 Advantages of Reusability:
 Productivity will be increases.
 Project development time is reduce.
 Cost is saved.

Software process:
 A sequence of steps performed for a given purpose.
 A set of activities, methods that are people used to develop and maintain system.
 If companies are not following process properly: Disadvantages: -
 Commitment consistently missed.
 Late delivery
 Last minute crashes
 Quality problem
 To much rework
 Functions do not work correctly.
 Customer complaint after delivery.
 People frustrated (End-User)
 Benefits of Process:
 Quality
 Consistency
 Traceability
 Early defect removal
 Reduce rework and rejections
 Control of cost
 On-Time

People:
 A people is a set practices performed to achieve a given purpose, it may include tools, methods
and materials or a people.
 The quality of product is largely determined by the quality of process that is used develop and
maintain it.
Process Model:
 A model is structure of collection of practices that describe characteristics of effective process.
 SEI – Software Engineering Institute at Carnegie Mellon University initiated by a US defense
department to help to improve software development process.
 CMMI: Capability Maturity Model Integration – The CMM for software has been retired and
CMM replaces it & it is developed by SEI. Its model of 5 – level of process ‘maturity’ that
determine effectiveness in delivery of quality software.
 Organization are receive CMMI ratings by undergoing assessments by qualified auditors.
 CMMI for system engineering & software engineering staged representation.
 Maturity Levels:
 Performed – (Initiation)
 Managed – (Management)
 Defined – (Technical)
 Quantitatively Managed (Quantification)
 Optimizing – (Process Improvement)

Process areas by maturity level:

 Performed – Overview:
Key Process areas (KPA’s):
o Introduction
o Structure of the model
o Understanding the model
o Usage of model
 Managed – Basic project management:

Key Process areas (KPA’s):

o Requirement management(RTM)
o Project planning
o Project monitoring and control (Status report)
o Supplier agreement management
o Measurement and analysis
o Process and product quality Assurance (Audits)
o Configuration management.(WinSCP)
 Defined – Process standardization :
Key Process areas (KPA’s):
o Requirement development
o Technical solution
o Verification
o Validation
o Organizational training
o Risk Management
 Continuously managed :

KPA:

o Organizational process performance


o Quantitatively project management
 Optimizing : Continuous process improvement :

KPA:

o Organization innovation & deployment (OID)
