Background


History1994: 16% of projects succeeded[1]

Average cost over run 180%

2004: 35% IT project being on time and within budget[2]

Average cost over run 43%

2007: 65% of IT Projects succeeded[3]

Effort < 200 person weeks

Nearly 70 percent of really big IT projects fail[4]

“It’s very easy to skip over requirements or make assumptions. RequisitePro drives us

to make sure we've covered everything.”

“With RequisitePro's suspect links, all team members can

immediately see changesthat are made…”

SCM

Easy traceability from the Requirements phase to Acceptance phase.

Good in knowing whether client’s expectations are met.

For big project teams, this is very good.

RequisitePro guarantees success of a Project by giving teams the ability to manage all project requirements, facilitating team collaboration and communication.

Not even a single requirement missed at any stage.


Design Tools


Why Design Tools? Requirements Analysis

Design

CodingUnit Testing


Tools help manage the visual design of the software system .Brings Consistency in understanding the design.Enforces the basic rules of design, based on the methodology chosen. (UML etc)Helps generate code templates from the design reducing the effort needed in coding.Tool helps reverse engineer code into design reducing re-documentation effort.HTML document generation for on-line document reviews.

Benefits

Code Generation: 35 Kloc of code was generated by tool out of total 110kloc i.e. 31.81% of automatic code generation.

Design Synchronisation: - Design and Code Intact

In general 4-8% of Code Generation is possible using Design Tools


Code Generation Tools

Automated building of high-level code

Tools range in size and complexity

Simple code parsers to fully featured class and tier builders

For Java and EJBs:interfaces, classes and beans from a description of the tables

Web Pages

For .NETASP.NET (web pages)

ADO.NET (DB connection classes) applications

MDA – Model Driven Architecture

Technology Pattern ExampleCreated a new technology pattern that creates a simple EJB modelContaining EJBSessionComponents with some predefined methods and tags.

Implementation Pattern ExampleCreates a simple utility class for Web components so that code is generated in addition to the other code generated for Web components.To get calendar control for data type in all the web pages

Software Configuration Management


Why Software Configuration Management? Requirements Analysis

Design

CodingUnit Testing


Managing Parallel ReleasesGreater Drive towards reduction in Time to Market

Multi-Vendor handling different modules

Different Vendors handling different releases

Maintaining all the changes and archiving information for easy accessibility by the team is difficult to enforce in manual systemGeographically Diverse Team accessing Code

Risk of changes made by one team member being overwritten by another
