Assignment 4 - Medco Breadth GradeB Observations+Addresses (in varying levels of detail) the major phases of the development life cycle: Analysis Design Development Testing Deployment Maintenance +At least mentions project management activities (misnamed “Project Plan”), though no further detail is provided -Does not address: Architecture Conversion planning, preparation, or execution Development environment Various facets of project management (e.g., risk management) QA

Assignment 4 - Medco Depth GradeD Observations+Provides high-level view of the process + Includes rudimentary deliverable flow -Need 1-2 additional levels of detail to ensure common understanding. Too much is left to interpretation. -Other than rectangle, no further detail on project planning/mgmt. In particular, more needed on how multiple releases will be managed simultaneously

Assignment 4 - Medco Alignment with Best Practices GradeC Observations+Addresses (to some extent) the following best practices: Iterative development Visual modeling Reviews Testing User involvement Deployment -Does not address: Architecture Component-based development Requirements management Change control

Assignment 4 - Medco Conceptual Integrity GradeA Observations+No major inconsistencies found + Process is basically vanilla structured analysis/design (proven, well understood), limits exposure to integrity issues -When there is not much depth, it is relatively easy to maintain conceptual integrity

Assignment 4 - Medco Fit with Project and Organization GradeF Observations+Process is at least documented, which it had not been before -This is a complex, mission-critical system; this methodology is far too sketchy for a project of this magnitude - Reliance on outside contractors makes it even more important to have a better document process -Intricacies of delivering releases every 2 months need to be planned out in further detail -This process seems to reflect an informal, entrepreneurial culture; but organization is growing/maturing and needs “methodology for grown-ups” -- the stakes are higher

Assignment 4 - Medco Summary Grade and Recommendations GradeD RecommendationsConsider replacing data flow diagrams with use cases Provide additional detail for existing coverage areas – Possibly use outside contractor/consultant Add coverage for key areas: – Project management – Development environment – Architecture – Conversion – QA process Ensure project team is trained on the methodology

CMM Levels Repeatable (2) Repeatable (2) Defined (3) Defined (3) Managed (4) Managed (4) Optimized (5) Optimized (5) Initial (1)

Key process areas (KPAs) Maturity levels Process capability Indicate Key process areas Contain Key practices Contain Goals Achieve

Appraisal Methods Software Process Assessments (SPA) –Performed in open, collaborative environment –Focuses on improving the organization’s software process –Now called CMM-Based Appraisal for Internal Process Improvement (CBA-IPI) Software Capability Evaluations (SCE) –Performed in a more audit-oriented environment –Focuses on identifying risks associated with a contractor –Team’s recommendation will help select contractors or set fees

CMM Issues in the Real-World “Level envy” Areas not addressed –Business strategy and linkage to IT –Operations, help desk, support –Management of the IT human resource –Application portfolio –Tools –Risk Many question whether it is worth the effort to pursue levels 4 and 5
