If youâre building a complex system, youâll gain knowledge while youâre building it, and youâll come up with better ideas for decisions you made when you didnât have the knowledge. Should it be rebuilt at this time or not?
- The school that should be rebuilt
- Trying to build a tower on a distorted foundation is a waste of adjustment costs.
- In the long run, we need to fix the foundation now.
- The school of thought that should not be reworked
- The unknown is just plain simple.
- Itâs about as complicated as it gets when you actually create it.
Isnât this âchoosing the wrong two optionsâ? Isnât there a third option and isnât that the right one?
The rebuilders believe that âthe difference between the cost of continuing with the incorrect design and the cost of the correct design exceeds the cost of rebuilding to the correct design in the long runâ. Those who do not rebuild believe that the new design, which they believe is the correct design, is not much different from the current design, and therefore the transition cost will not pay for itself. The discrepancy between these two opinions is the difference in estimating the quality of the ânew designâ This is âhighly uncertainâ because âwe havenât made it yet,â so itâs not surprising that there are differences in estimates.
A third option, âReduce uncertainty at minimal cost.â
-
Whether a new design is really worth ârebuilding on itâ should first be verified at minimal cost
