Q

What is the WSJF formula?

A

WSJF = [Cost of Delay] / [Job Duration]

==OR==

WSJF = [(User-Business Value) + (Time Criticality) + (RR or OE)] / [Job Duration]

  • RR = Risk Reduction
  • OE = Opportunity Enablement

Q

What 3 values are used to calculate the Cost of Delay?

A

User-business value – What is the relative value to the customer or business? Do our users prefer this over that? What is the revenue impact on our business? Is there a potential penalty or other negative effects if we delay?

Time criticality – How does the user/business value decay over time? Is there a fixed deadline? Will they wait for us or move to another solution? Are there Milestones on the critical path impacted by this? What is the current effect on customer satisfaction?

Risk reduction-opportunity enablement value – What else does this do for our business? Does it reduce the risk of this or a future delivery? Is there value in the information we will receive? Will this feature enable new business opportunities?

Q

What happens during a “Retrospective and Problem-Solving Workshop”?

A
  1. Retrospective
    1. team problem identification activity
    2. goal is to identify system issues to be addressed (program-level in scope)
    3. teams contribute own views of the problem
    4. identified issues ‘seed’ the problem-solving workshop
  2. Problem-Solving Workshop
    1. Agree on the problem to solve
    2. Apply root cause analysis
    3. Identify the biggest root-cause using Pareto Analysis
    4. Restate the new problem for the biggest root cause
    5. Brainstorm solutions
    6. Identify improvement backlog items
