The Software
Development Paradox
IBM Software Group | IBM Rational software
How Is Business Doing?
 Over 30%1 of software
projects are cancelled
 Of the remaining 70%, many are
over budget, over time, or defective
functionally
 52%1 of software projects
cost 189%1 original estimates
 Only 16%1 of are completed on
time and within budget
 For large enterprises, this can be as
bad as 9%1

Why are organizations failing?
 Hitting the wall before release (1)
 Losing/adding team members
 Unforeseen technology difficulties
 Unforeseen or changing requirements
Figure-1
 90% done (2)
 Riskiest features deferred
 Endless Q&A (3)
 Poor quality code
Figure-2
 Bugs found late are very costly
 Negative ROI
 Failure Traps – Balance and Guidance

Software Development Obstacles
 Environment Complexity
 Process Complexity
Limited tooling - legacy tools,
compilers, integrations
No defined development
process
Lack of built-in debugging and
testing capabilities
Lack of understanding
Host Platforms – Linux, UNIX,
zSeries
 Application Complexity
Legacy systems – difficult to
maintain / understand / modernize
Hard to maintain
Architectural enforcement or
knowledge
Inadequate testing
Poor performance
Transaction driven – highly
unpredictable events and loads
Unreliable builds
Strong timing constraints –
realtime requirements
Missing integration
Concurrent / Distributed /
Networked
Changing requirements
Disparate tools
lacking required integrations
IBM Software Group | IBM Rational software
Transforming for Success: What is Required?
 Good / Complete Planning
 Complete Requirements & Specification Definition (end-user signoff)
 Requirement Management and Implementation Control (ie., what shall get built
and when)
 Clear Responsibility and Accountability of Team Members
 Individual workflows
 Clear communication paths
 Schedule Control
 Software Configuration Management, Activity, and Test Managenment
 Project Statistics
 Clear Communication and Validation
 Architectural Enforcement
 Test Validation and Support
