Architecture design
RDD- In detail what features the system should have.
Service-Oriented Architecture what is it ?
systems are assembled from relatively independent software components, each handles specific business service. t
Implementation process and what does it involve ?
System delivery
Parallel Implementation
Phased Implementation
Direct Implementation
Parallel Implementation and what is it?
Launches new system while the old one is still running
very expensive, only for a short period of time.
Employees do their job twice
Phased Implementation and what is it?
Launches models in phases rather than all at once
Direct Implementation what is it ?
Switches off the old system and launches all the modules of the new one on a single, very hectic-go live date
Waterfall Method and what does it do?
The SLDC tasks occur right after each other, one activity starting right after the other one is done.
Iterative method and what does it do?
Partly reduce the impact of fast changing business needs and the resulting re-work
Focus on the time available until the next release and the development team determines how many of the requirements it can deliver.
Common approach is RAD- rapid application development
Agile methods and what does it do?
Less structured approach where task are not sequenced according to the SDLC instead the activities occur simultaneously .
what is methodolgy and the 2 types
Predicitve is one time
and Adaptive
The water fall method or sequential
Parallel Development
Throw-away prototyping
What is a project?
sequence of events or activities having a single goal or purpose and must be completed.
they are one of a kind
must be done with in a specific budget, specific time
What is project management?
Planning and controlling development of a project within a specified time frame at a minimum cost
goals for PM?
Complete on time
Complete the project within budget

If one changes it affects the whole thing
The constraints could be fixed
Project management and its 5 stages
Intiating stage in PM
Ground work
Project charter

the tasks must be completed before going on the next one.
Closing stage in Pm
End in an orderly way
Document Lessons learned
Project management software
Manage time
Managing people and resource
Managing costs
Projects why they fail?
Lack of executive support
Unclear requirements
poor communication
Poor project planning
Spend 80% of their time i exception instead of in the project start up
One of the biggest reason projects fail is because there is no little business case for the subject
Success factors for Project managment
Define the job detail
Empower the team- the right team
Do complete plan
