The tills are ringing, is it because of your strategy?

Strategy development is a supposed to be a dynamic process whose intended outcomes should be a better company in the eyes of all KEY stakeholder, namely Customers; Shareholder; Employees; Suppliers; Competitors; Management; Boards, etc.
Whether a consulting entity helped the strategy development process or you knuckled down and developed this yourself, beyond a specific defined and agreed to date, the tills must start to ring to show that the strategy was to an extent spot on. What if the tills ring BUT its not because of the approved strategy. What if your employees adapted your strategy to ensure that the tills ring in the short term thus guaranteing their bonuses? Does it really matter in the short-term or what about in the medium term and eventually in the long term? What if you are responsible for generating short term gains with the hope that the mid to long term will take care of itself? What rules exist to mitigate gainst these shortsighted  behaviours. Should strategists be on the look out for such practices and disown them?
