2. Discussion starting point Start with the working assumption that the objective is maximizing the expected value of M = B – C, where M = margin (contribution to profit), B = bid (price), C = cost (direct), and assume we want to understand the expected values of M, P and C plus associated risk. Start with C for two components which are useful examples.

5. Linking this to common practice • The value of simple ‘other objective’ assessments early on. • The value of simple initial cost estimates. • The value of the ‘risk efficiency’ concept and its assessment via simple linear cumulative probability distributions.

6. Some concluding comments • The key estimating process ideas have been used very successfully by a limited number of organisations. • Many of the key ideas can be applied to all opportunity, risk and uncertainty management processes.

8. Discussion starting point Keep to the working assumption that the objective is maximizing the expected value of M = B – C, where M = margin (contribution to profit), B = bid (price), C = cost (direct), and assume we want to understand the expected values of M, P and C and associated risk. Now look at C when discrete events are involved.

14. Some concluding comments • The value of simple ‘other objective’ assessments early on. • The value of simple initial cost estimates. • The value of decision trees that do not need exact probabilities or consequences. • The value of the generality of a minimalist view of uncertainty as part of a clarity efficient perspective. • Many of the key ideas can be applied to all risk management processes.

16. Discussion starting point Still use the working assumption that the objective is maximizing the expected value of M = B – C, where M = margin (contribution to profit), B = bid (price), C = cost (direct), but assume we want to understand the expected value of C in total, and associated risk.

19. Linking this to common practice • The value of simple estimating processes. • The value of more complex estimating processes in their own right and as the basis of simple estimates. • The key estimating process ideas have been used very successfully by a limited number of organisations.

20. Some concluding comments • Many of the key process ideas can be applied to all opportunity, risk and uncertainty management processes. • Designing processes for contexts is an overarching key idea. • Seeking simplicity systematically in these processes is another key idea, introducing complexity where it pays being a crucial part of this.

Discussion starting point Still use the working assumption that the objective is maximizing the expected value of M = B – C, where M = margin (contribution to profit), B = bid (price), C = cost (direct), but assume now that we want to use an expected value for C from part 3, assume values for B, and understand the implications for M.

29. Samdocase study discussion

30. Discussion starting point Start with the working assumption that the objective is maximizing the expected value of M = R – C, where M = margin (contribution to profit) per year, R = revenue, C = cost (direct and amortisation of capital), and assume we want to understand the expected values of M, R and C plus associated opportunity and risk. Begin by considering R.

31. Key components of R (revenue) • base load power sales to Ontario Hydro • waste heat (low pressure steam) • back-up emergency power We need to size these components, then identify associated key sources of uncertainty, and associated key responses (decisions).

32. Key components of C (cost) • amortised capital cost • fuel cost • other costs We need to size these components, then identify associated key sources of uncertainty, and associated key responses (decisions).

33. Creative thinking putting this together • New untested design CCTG plant? • Defer emergency power business? • Back-to-back contract with Ontario Hydro? • Back-to-back contract with gas supplier? • Timing issues?

34. Some concluding comments • The top-down process starting point is useful here. • Many of the key generic process ideas can be applied to all opportunity, risk and uncertainty management processes. • Designing processes for contexts is an overarching key idea. • Seeking simplicity systematically in these processes is another key idea, part of the overarching opportunity efficiency concept.
