Goals for Session
Convey basic information about the Software Development Lifecycle (SDLC)
Identify basic processes and a basic vocabulary regarding (SDLC)
Identify sources for additional information.

SDLC Process
Develop Requirements Determine Architecture Implement New Code or Changes Test System Functionality Deploy New Functionality

Vocabulary - Models
Waterfall (sequential)Requirements, design,
implement, test, integration, and maintenance
Iterative (cyclical)AgileRational Unified Process (RUP)Rapid Application Development)
(RAD) 5

Requirements (In a nutshell)
10
Develop Requirements Complete Consistent Prioritized Structured Traceable
11
Determine Architecture
Department of Defense Architecture Framework (DODAF) – standard way to organize an enterprise architecture into a complimentary and consistent view.
Zachman Framework – formal and highly structured way of defining an enterprise.
Federal Enterprise Architecture – common methodology for IT within government.

Sample System Architecture
16
Implement New Code or Changes Computer Programming – process of writing code. Source Code – sequence of statements or declarations
written in a programming language. Programming Language – artificial language used to control
the behavior of a machine. Python Java
17
Test System Functionality Testing Traceability Matrix – mapping the requirements to the
test cases. Test scripts – scenarios designed to test a system. Regression Testing – ensuring that adding new functionality
did not result in “breaking” what worked before. User Acceptance Testing – the process of testing with
functional users. Integration Testing – the process of testing new functionality

Notes
Award Classification Testing
Test for generation of single honours qualification (all possible classifications according to the weighting for the award).
Schools to run tests for production of classifications for all the scenarios they have.
Test for generation of combined honours in two disciplines qualification (all possible classifications according to the weighting for the award).
Schools to run tests for production of classifications for all the scenarios they have.
Test for group honours qualification generation (all possible classifications according to the weighting for the award).
Schools to run tests for production of classifications for all the scenarios they have.
Test for Integrated Masters with honours qualification (all possible classifications according to the weighting for the award).
Schools to run tests for production of classifications for all the scenarios they have.
Vocabulary – Supporting DisciplinesConfiguration Management – revision
control.Documentation – written text that accompanies
computer software.Software Quality Assurance – monitor
software engineering process usually via audits.Project Management – discipline of organizing
and managing resources so that projects have a defined scope, quality, time and costs constraints.
User Experience Design – designing to a users satisfaction.
22
Vocabulary - Standards
ISO 12207 – lifecycle for software. CMM or CMMI – capability maturity model
integration. ISO 9000 – quality management systems. ISO 15504 (SPICE) – software process
improvement and capability determination. Six Sigma (manufacturing-oriented) – practices
to systematically improve processes.

Additional Information
Do a google search on SDLC – you will find Software Development Lifecycle and System Development Lifecycle. Both define process methods.

Suggested Questions
Hey<name>, for the 2008-2009 AY, do we need to develop or adjust our standard templates for requirements gathering so that we improve our SDLC process?
25
Suggested Questions
Hey<name>, do we practice a waterfall or iterative process for our SDCL? Or do we use both processes depending on the expected changes?
26
Suggested Questions
Hey<name>, I know that you’re going to need FAO input for the 2008-2009 changes. Can we get together to develop a project plan? I want to make sure that you have the resources you need for requirements gathering and testing.
