I like to use it to explain why projects so often go wrong, why iterations are good (shorter cycles if there are cycles) etc. Another great use is to use probabilities instead of 1 or 0 elements so that it is a matrix representing the probability distribution relating the different process steps, eg. instead of a 1 denoting "requirements are the input to development" we could have two inputs to dev "70% requirements to dev, and 30% requirements changes to dev from 'oh that's not what I wanted' downstream. This can be used to calculate the ratio of work and rework and explain the high cost of change - in fact, even in simple models with many steps there is a dramatic difference between operating the steps at a defect rate of 10% and 1%, since the probability of staying on the correct-first-time-through path is very low until the defect rate is reined in. Get in touch if you would like to know more - I have some models that I could post if you are interested. All the best, Martin It’s nice to see your interest in DSM.
