It is also easier to identify pieces that do not belong in the puzzle and can be set aside. In development you have a clear view of many objectives. You can use that view much like the picture on the top of the box the puzzle came in that shows the completed puzzle. That speeds up the process of discarding irrelevant pieces of information and of locating the part of the puzzle where a relevant piece may fit. This form of jigsaw management works for administration and for many business issues.
Basic research is different.
In research and invention there is no boxtop to build from. The visualization process that works for overall management does not work in creative endeavors like these. The puzzles encountered in research and invention resemble the challenge presented by a jigsaw puzzle when the top of the box has been hidden away before the pieces are dumped on the table. When this happens, intuition becomes the key. Intuition causes one to look at the pieces for likely corners or parts of an edge.
