Why a focused approach?CMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University6

Why a focused approach?Introduction to CMMI provides an overview of the entire model;students receive a large amount of information quickly.Intermediate Concepts of CMMI provides advanced information forSCAMPI Lead Appraisers and CMMI Instructors.A focused approach serves the needs of the many practitioners whoare working at or toward levels 2 and 3.Because CMMI implementation happens step by step, a focus on thechallenges at specific levels is a natural fit and can providepractitioners with the tools they need to effectively implement CMMI atlevels 2 and 3.CMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University7

Format for discussing each process area (PA) What does this PA involve? Value Dependencies on other PAs Ordering of specific practices Selected specific practices Selected generic practices PA implementation considerationsCMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University18

Requirements Management Process AreaThe purpose of Requirements Management (REQM) is tomanage the requirements of the project’s products and productcomponents and to identify inconsistencies between thoserequirements and the project’s plans and work products.CMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University19

REQM involves Managing the requirements as the product evolves understanding requirements obtaining commitment to requirements recognizing and receiving requirements changes and making decisionsabout how to handle them ensuring customer requirements, project work, and products areconsistent with product requirementsCMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University20

Value of REQMRequirements management processes prevent inconsistencies between the approved requirements and theproject’s plans and work products assess which requirements, work products, and product components areaffected by a proposed change ensure customer requirements, project work, and products are consistentwith product requirementsCMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University21

REQM depends on Requirements Development for establishing and maintaining customer, product, product component,and interface requirementsConfiguration Management for controlling changes to requirementsProject Monitoring and Control for taking action to correct identified inconsistencies amongrequirements, project plans, and work productsCMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University22

PAs that depend on REQMProject Planning for managing requirements needed for planning and replanningSupplier Agreement Management for managing the requirements that will be satisfied by external sources for managing the traceability of requirements for products acquired fromsuppliersRequirements Development for managing customer, product, and product component requirements;obtaining agreement with the requirements provider; obtainingcommitments from the requirements implementers; and maintainingtraceabilityCMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University23

Polling questionsHow do you feel about the information you’re receiving in thiswebinar? Too technicalNot technical enoughJust RightIs the information you’re receiving relevant to your organizationor job? YesNoDon’t KnowCMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University25

SP 1.1 Understand RequirementsDevelop an understanding with the requirements providers on themeaning of the requirements.It is important to understand what the project is building. subpractice 1:Establish criteria for distinguishing appropriate requirements providers. subpractice 4:Reach an understanding of the requirements with the requirementsprovider so that the project participants can commit to them.Typical work products lists of criteria for distinguishing appropriate requirements providers criteria for evaluation and acceptance of requirements results of analyses against criteria an agreed-to set of requirementsCMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University26

SP 1.2 Obtain Commitment to RequirementsObtain commitment to the requirements from the projectparticipants.Project participants must commit to the approved requirements and theresulting changes to their project work. subpractice 1:Assess the impact of requirements on existing commitments.Typical work products requirements impact assessments documented commitments to requirements and requirements changesCMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University27

SP 1.3 Manage Requirements ChangesManage changes to the requirements as they evolveduring the project.Requirements change! It is important to effectively manage thesechanges. subpractice 1:Document all requirements and requirements changes that are given toor generated by the project. subpractice 3:Evaluate the impact of requirements changes from the standpoint ofrelevant stakeholders.Typical Work Products requirements status requirements database requirements decision databaseCMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University28

SP 1.4 Maintain Bidirectional Traceability ofRequirementsMaintain bidirectional traceability among the requirements andwork products.It is important to identify which work products are affected by aproposed change. subpractice 2:Maintain requirements traceability from a requirement to its derivedrequirements and allocation to functions, interfaces, objects, people,processes, and work products. subpractice 3:Generate the requirements traceability matrix.Typical work products requirements traceability matrix requirements tracking systemCMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University29

SP 1.5 Identify Inconsistencies BetweenProject Work and RequirementsIdentify inconsistencies between the project plans and workproducts and the requirements.It is important to know when something is moving “out of synch” withthe currently approved requirements. subpractice 1:Review the project’s plans, activities, and work products for consistencywith the requirements and the changes made to them. subpractice 4:Initiate corrective actions.Typical work products documentation of inconsistencies including sources, conditions, andrationale corrective actionsCMMI Level 2 for Practitioners WebinarMary Beth Chrissis May 27, 2009 2009 Carnegie Mellon University30
