Becoming a Certified Software Development Professional (CSPD)andOverview of The Software Engineering Body of Knowledge (SWEBOK) (Required reading SWEBOK Chapters 1 and 2 Text Ch 1-4)
The SWEBOK Guide • Task Force • Objectives • Promote a consistent view of SE worldwide • Clarify the place and boundaries of SE relative to other related disciplines • Define/characterize the contents of the SE discipline • Provide access to the various components of the SWEBOK • Provide a foundation for curriculum development and individual certification and licensing
The SWEBOK Guide Cont’d • A guide to describe the core of the SE Body of Knowledge • Broken into Knowledge Areas
How we will use SWEBOK • Has many “definitions” of most key terms, you will be required to know the terms defined in the chapters assigned. • Has references to primary material (and occasional textbooks), you can use later when/if you need more details. • Only doing an overview, you are expected to know what is there, not necessarily how to do it. • Really covering the SWEBOK takes 5-8 courses!
Knowledge Areas • Establishes boundaries that identify engineering disciplines • May share common boundaries with other disciplines • Does not attempt to describe all of the knowledge within SE
Knowledge Areas Cont’d • Captures a subset of “generally accepted” knowledge or the core of SE
Knowledge Areas Cont’d • There are 10 KAs in the SWEBOK • Each KA contains a reasonable topic list presenting sound information about SE • Excludes specific knowledge regarding application domains, business, technology, SLCs and development methods • Compatible with what is generally found in industry
Knowledge Area Cont’d • Each KA follows the KA Description Specification • Includes description, topics, related areas and reference materials.
The Repeatable Process • The first 5 KAs cover the repeatable process • Requirements • Design • Construction • Testing • Maintenance • Define KA used in the development of software management processes • Together the are comparable to the definition of CMM level 2 excluding business specific knowledge
Software Requirements • Requirements engineering process • Requirements elicitation • Requirements analysis • Software requirements specification • Requirements validation • Requirements management
Software Design • Basic concepts • Key issues of software • Structure and architecture • Software design quality analysis and evaluation • Design notation • Software design strategies and methods

Software Construction Cont’d • Principles of construction • Reduction of complexity • Anticipation of diversity • Structuring for validation • Use of external standards Where does the Software Engineer learn to construct software? Is Computer Science a required related discipline?
Software Testing • Basic concepts • Test levels • Test techniques • Test-related measures and management
Software Maintenance • Basic concepts • Maintenance process • Key issues • Techniques for maintenance Is there a SENG course that covers software maintenance?
Related Disciplines • Computer Science • Mathematics • Projects Management • Computer Engineering • Cognitive Science and Human Factors • Systems Engineering • Management and Management Science
The Defined and Managed Process • The last 5 KAs cover the defined and managed process: • Software Configuration Management • Software Engineering Management • Software Engineering Process • Software Engineering Tools and Methods • Software Quality Analysis • Together they are are comparable to the definition of CMM level 3 and 4
Software Configuration Management (SCM) • Management of the SCM Process • Software Configuration Identification • Software Configuration Control • Software Configuration Status Accounting • Software Configuration Auditing • Software Release Management and Delivery
Software Engineering Management • Organizational Management • Process/ Project Management • Software Engineering Measurement
Software Engineering Process • Software Engineering Process Concepts • Process Infrastructure • Process Measurement • Process Definition • Qualitative Process Analysis • Process Implementation and change
Software Engineering Tools and Methods • Software Tools: requirements tools, design tools, Construction tools, testing tools, maintenance tools , engineering process tools, quality tools, configuration management tools, engineering management tools, infrastructure support tools, Miscellaneous tools issues • Software Methods: • Heuristic • Formal • Prototyping • Miscellaneous

An Organizational alternative • What is CMMI, and how related to PSP and CMM. • What is required to achieve CMMI? • Relating CMMI and EIA 859!
What is CMMI? • Defines 5 levels of process maturity • Describes model framework to be used for: • Assessing process maturity • Determining priorities • Instituting process improvement Capability Maturity Model Integration CMMI
Relation to PSP and CMM • PSP is the Personal Software process, and is basically a “process” (supported by course material to teach it) for an individual to follow a capabilities-based maturity model. • CMM is the older SEI Capability Maturity Model, strictly for Software Development. CMMI is a generalization that covers more systems and project issues as well as business processes.
