Goals

A familiar story:  We are trying to defend an area from the enemy and have set up some fire bases.  A squad of men with small arms behind a sandbag barrier will shoot at the enemy from these fire bases. The bases will be much more effective and the men safer if they can support each other with small arms fire so we carefully measure the elevation and place the bases on high ground for maximum vision, clear jungle and some old buildings to improve the line of sight, and install firing platforms to improve stability and accuracy.  We demonstrate the effectiveness of this configuration via simulations and congratulate ourselves on a job well done. 
 
Oh,  remember those old buildings?
 
Yes senator, it became necessary to destroy the village in order to save it.
 
We have all seen and done this many times on our projects: gotten so tied up with tasks and process that we loose sight of the goal.
