The obstacles to an injection do not necessarily identify every task that is needed to implement it.  There may be other activities that need to be undertaken.  Therefore check the project for sufficiency. 

The sufficiency check comes from your and others intuition, general knowledge and experience .

Add any Intermediate Objectives identified or activities and tasks to the IO table and amend your project plan accordingly.  The Jonah analysis process is then complete.  

Now you can see how good you are at implementing change?

Implementing change is never straight forward, be aware, check for unforeseen obstacles and use the Jonah processes to identify how to overcome these.  The plan is living working document - work with it review it, take it to project meeting make sure others are using it too.  A project plan is a great communication tool.
