making it difficult to know when they are overcommitting during a sprint’s planning day. Varying the time box will also require the team to rederive the unwritten sequence of minideadlines that occurs between teammates within an iteration, an understanding that can take the developers several spr...
A common usage for theforstatement is to iterate through an array of elements, especially if you need some control over the manner in which the iteration happens. While theforeachiterates through every element of the array, theforstatement can be tweaked to provide more customization. ...
Our assessment results have helped us keep, map, and prioritize areas that are suffering from weak or absent controls for defensive initiatives and identify areas poised to benefit the most from offensive Playbook sequences. The mix of defensive and offensive initiatives required over any period of...
