I am a great believer in going lean in everything except my waistline or my cooking.
Going lean means cutting excess where you find it so that you can get from point A to point B as cheaply, quickly and easily as possible.
Cheaply doesn’t mean being cheap – spend money where it’s needed; cut excess expenditure where it is not.
Quickly doesn’t mean fast – heading 100mph in any direction is less preferable than heading 5mph in the correct direction; but sometimes any direction is better than no direction when you don’t know which direction to go in.
Easily doesn’t mean by any means necessary – it means removing the sticking friction that is holding back the advancement of a project; easily is related to quickly – if you cannot move forward quickly you cannot move forward easily.
