The SDLC/PMI Mixup Phenomenon


The SDLC Phases• Planning• Analysis• Design• Implementation• Operation and Support


Planning and Analysis

• Planning– Formal request– Preliminary investigation– Feasibility analysis

• Analysis– Requirements gathering– System requirements documentation

Review the “Getting Your Hands Dirty with SDLC – Planning and Analysis” section of the case study – page 346


Design• Think “blueprint”• Systems are broken down into

successively smaller levels until discrete working entities are denoted

• Describe each of those entities and how they interface with their partner components to make the wholeReview the “Getting Your Hands Dirty with SDLC – Design” section of the case study – page 347


You Decide

• You’re building a shed. – What are the smallest subcomponents to the

construction project that you can describe?

• You’re building a gingerbread house for a competition. – What are the smallest subcomponents to the

project?

• Your team is building a new computer system for Internet sales transactions. – What are the smallest subcomponents to the

project?


Implementation

• Think “system construction”• Software development, testing, and

documentation• Data conversion• End-user training• Migration from the old system (if

any) to the newReview the “Getting Your Hands Dirty with SDLC – Implementation” section of the case study – page 349


You DecideWhat other implementation elements might be needed when developing an enterprise-class system? (Hint: Think telecommunications, training, and support from other teams.)


Operations and Support• Think “system go-live”• Manage minor changes & updates• Support of users & system

components• New versions not part of O&S. New

versions mean a new project.Review the “Getting Your Hands Dirty with SDLC – Operations and Support” section of the case study – page 350


You DecideYou’ve deployed your new Internet catalog and shopping system for your customers. Of the following elements below, which are probably not part of the Operations and Support phase?– Addition of new languages to the current

system (English & Spanish only on current system)

– Online chat (didn’t exist at deployment time)– Adding of American Express card support– Provision of a “wish-list” page for frequent

visitors
