How do you prioritise?

Does it sound a little like this?

Priority Choice – Mixed Duration, Mixed Value

Base  Decisions  on  Economics  

Develop  an  economic  framework  for  decision  making  

! Empower local decision making

! Do not consider money already spent

! Sequence jobs for maximum benefit

!  If you only quantify one thing, quantify the cost of delay

Cycle time Cost

Value Development expense

Risk

—Don Reinertsen, Principles of Product Development Flow

“Understanding economics requires understanding of the interaction amongst multiple variables.”

Why Quantifying the Cost of Delay Matters

13  

Weighted Shortest Job First (WSJF)

•  In order to calculate WSJF we need to estimate Cost of Delay and Duration

•  Relative estimating is a quick technique to estimate job size and relative value

•  For duration, we will use job size as a quick proxy

WSJF    =                                      =  User-­‐Business  Value    +    Time  Cri7cality    +    RROE  Value

Components of Cost of Delay

Relative value to the customer or business •  They prefer this over that

•  Revenue impact?

•  Potential penalty or other negative impact?

How User Business Value decays over time •  Is there a fixed deadline?

•  Will they wait for us or move to another solution?

•  What is the current effect on customer satisfaction?

What else does this do for our business •  Reduce the risk of this or future delivery?

•  Is there value in the information we will receive?

•  Enable new business opportunities?

Prioritise SAFe City, based on cost of delay and job size

Instructions:

!  Prioritise your development items using CD3

!  Estimate each backlog item one column (not row) at a time

!  You don’t have to estimate job size at this time
