We all know good scheduling leads to better project outcomes – certainly for me it’s been a article of faith for most of the last 40 years and ‘obvious’ from observation. But ask me, and any other scheduler I know to prove this fact and we would be hard pressed to come up with anything substantive.
Over the years there have been many surveys that link the lack of effective planning to poor project outcomes. One of the more definitive was undertaken by the CIOB in 2008 (download the report ‘Managing the Risk of Delayed Completion in the 21st Century’). But showing projects tend to fail if they don’t use effective planning and scheduling is not the same as showing that good planning and scheduling enhances the probability of success.
This has now changed! A paper published by Dr Dan Patterson, the CEO of Acumen, demonstrates a clear link between good schedules (defined as technically competent schedules) and good project outcomes.
Figure 1, taken from Dan’s paper Does Better Scheduling Drive Execution Success? Published in November’s PM World Today shows a strong correlation between the technical competence used to develop the schedule and the number of activities that finished on time. The data is based on a sample of 35 large projects ranging from US$15 million to US$30 billion.
Link the CIOB findings with Dan’s data and the message is blindingly obvious – if you are running a large project without a competent scheduler supporting the management team with effective scheduling, you are virtually guaranteeing failure!
Hopefully the work currently being undertaken by Planning Planet, CIOB and others to develop a framework (or frameworks) to train and qualify competent schedulers will mean in the next year or two there will be enough good schedulers to meet the demand from business and industry. For more on this see: Should you certify your schedulers? and watch this space…. There are a number of announcements due in the next couple of weeks.
