MAIN REASONS FOR UNSUCCESSFUL INFORMATION TECHNOLOGY PROJECTS
Kerli Metsla
FAILURE OF SOFTWARE PROJECTS Highest probability of being cancelled or
delayed among all business activities
Even if in budget and on time:
low reliability + execcisve errors
Capers Jones & Associates 2006
CRITERIAS OF BEING A FAILURE
Cancellation x Budget + 30%
Schedule +30%
Missing the planned benefits
Whittaker, B. (1999). What went wrong? Unsuccessful information technology projects
MAIN REASONS Survey in Canada
A. Poor project planning
B. Weak business case & missing components
C. Lack of management involvement &
lack of management support
Whittaker, B. (1999). What went wrong? Unsuccessful information technology projects.
A: POOR PROJECT PLANNING
Most common
RISK MANAGMENT IN SCHEDULING!
I am not done yet! What do I do now?
B: WEAK BUSINESS CASE
1. Missing several immportant compontents
2. Key users do not understand : Complexity of the deliverables „That´s a piece of cake“ Funding done without enough research to the
importance of the software to the business„Do we really need this? Who is going to use it? How much time do we have?“
C: LACK OF MANAGEMENT INVOLVEMENTAND SUPPORTDoom from the start!
Leads to:
„ This new thing is complicated. I´ll stick to the GOOD OLD one.“
„I don´t understand it, let´s change it. Most of it. OK, all of it. „
OFTEN CONTRIBUTE TO FAILURES
Delivering an untested (BETA) versions of theproject – full of bugs
Vendors to not deliver on time or at all
Poor estimates and definition of requirements in project specifications
The bigger the company the bigger the bugdet overruns (lack of skills or expertise of the project manager and monitoring of progress)
Whittaker, B. (1999). What went wrong? Unsuccessful information technology projects.
DIFFERENT VIEWPOINTS
Plan not accurate enough
Wrong status reporting
Poor quality and reliability
Rejection of accurate and conservative plan
Schedule pressure Major new
requirements mid development
Jones, C (2006). Social and Technical Reasons for Software Project Failures.
EXECUTIVES DEVELOPERS
THE FIVE ROOT CAUSES 1. Inaccurate scheduling Needed before final version No historical data Changes and addiotions Modern estimating tools do not apply well on major
projects Executives pressure in changing original schedules
2. Too optimistic status reporting Managers not trained enough – too optimistic Expected bugs vs actual bugs
Jones, C (2006). Social and Technical Reasons for Software Project Failures
THE FIVE ROOT CAUSES 3. Unrealistic schedule pressure External business deadlines sets the terms Need to defend original estimates
4. Changes mid project Businesses are dynamic
May lead to bankruptcy (UK second largest: Auto windscreens 2006); Integrated National Crime Information System (INCIS) project in New Zealand.

THE FIVE ROOT CAUSES
5. Inadequate quality control Fixing bugs : most expensive part + delaying
the project.
„A distressing number of project managers are not aware that more than 50 years of empirical studies have proven that projects with effective quality control cost less and have shorter schedules.“ (Jones, 2006)

CONCLUSION
HOW TO AVOID MY PROJECT FROM FAILING?
1. Plan the project with management well informed2. Risk management! 3. Accurate information (research for scheduling)4. Teamwork = managers + developers (reporting)5. No large changes mid project6. Correct status reporting – no „basicly done“7. Quality control – do not skip or do poorly!
