Another problem with the decomposition of Figure 2-1 is that it requires multiple points of entry to the system. The

Workflow volatility.

Make an explicit effort to list the areas of uncertainty in the project and focus on estimating them. Always break down large activities into smaller, more manageable activities to greatly increase the accuracy of the estimations.

Design Factoring

The presence of a nested “if” tells you that you should draw the use case.

Overall Project Estimation

Connection and synchronization volatility.

since the only way to know how long it will take and how much it will cost to deliver the system is to figure out first how you will build it. Consequently, each project design option comes with its own set of assembly instructions.
