To see the big picture sometimes we drill down. I give a specific example (completely fictional of course - this is not you, so don't call please). In this project BA 007 was asked to help introduce BA practices into a water utility's IT project practices.
The usual "fire hose" of information was sprayed on 007 for the first weeks. As 007's intelligence base grew, one of his early questions was "How much money is currently spent on IT projects and infrastructure per year?" The response was: "Oh, we have that, it's around $3,000,000.00". No documentation available, but, what the heck, eh?
So 007 continued to analyze the information he was getting, patient and secure that his question had been, or would be, answered. As an initial business case for implementing BA for IT projects began to emerge, it became apparent that the out of pocket costs looked something like the following:
- 12 SMEs on staff acting as BAs
- 8 person team doing requirements for ERP enterprise project
- 100 stakeholders engaged part time at any given time (about 10 full time equivalents)
- 70 Contract IT personnel
- Average IT Infrastructure investment of $3,000,000/year
Total 100 personnel out of 2700 employees @ $75K/year on average = $7,500,000/year
At this point, 007 starts to suspect that the $3,000,000 only covered total annual infrastructure costs (hardware, software, support and maintenance), and that the client was not counting payroll or overhead costs for projects (not unusual in a government environment). Given the 35% failure rate across all water utility IT projects (we ignore those that were merely "compromised"), the "lost money" to failed projects seemed more like $2,625,000 per year, or $26,250,000 over 10 years.
The costs of BA (requirements) failure above are incomplete and incorrect - they do not include overhead like office space, supplies, PCs, office equipment and other resources wasted on failed projects (promotion of the guilty, punishment of the expert, rock bottom morale, employee turnover and more).
The cost of retraining personnel for improving the BA function at the water utility was calculated to be 20 BAs plus 20 IT personnel, Each receiving 8 weeks of training in year one, 4 weeks in year two, and two weeks per year in subsequent years. Classes were estimated at $3500/week including travel, and salaries/benefits at $75K per year on average.
It was also estimated that increased/improved BA activity would require twice as much involvement from stakeholders - 20 full time equivalents instead of 10.
These costs to invest in BA came to about (40*(8+4+2+2+2+2+2+2+2+2) person weeks * ((75,000/52) +3,500) per person week)
PLUS 10 more full time equivalents @ $75K * 10 years
= $ 7,500,000
OK, those of you who do real business cases know just how flawed this is, but, as 007 likes to say, $26M - $13M gives a LOT of room for refinement. Go ahead, add inflation to personnel costs, add in lost benefits to the "merely wasted" money, add any complexity you want - 007 defies you to show that BA investment can ever lead to a negative ROI.
Have fun, and I'd love to get your feedback!
