Agile Abuse – Scenario 5 – Let’s play with estimation whenever we want
 

Ron – Developer 1, Amy – Scrum Master

Amy – How come we committed 45 story points and we accomplished 51 though I have not added any extra work to sprint.

Ron – The performance improvement story was a little complicated hence I have added 6 additional points to it.

Amy – Once an estimate is done, it is not supposed to change in any case. If so, the whole point of estimation has no value.

Ron – Sorry, I will change that back to original and add the challenges encountered with that story to our process asset library.

Challenge – It is perfectly alright to play with estimation at any point in time.  

Scenario 6 – Story point is not about time, not even a range
