product, ux & customer framework
Sequence work by cost of delay divided by job duration/size.
quick answer
Weighted Shortest Job First (WSJF) is a scoring table for Prioritization. It turns the decision into named fields, evidence, and a visible weighted shortest job first (wsjf) worksheet / visual.
The output should make the tradeoff visible enough for someone else to inspect, challenge, and act on.
Sequence work by cost of delay divided by job duration/size.
Use Cost of Delay when its output is closer to the conversation you need: Quantify impact of delaying a work item.
worked example
A filled example is easier to understand than a blank template. Use it to see the shape before applying the framework to your own case.
WSJF ranks cost of delay relative to job size so economically urgent small work rises.
WSJF ranks cost of delay relative to job size so economically urgent small work rises.
generate yours
Start Ask PL with the framework, required inputs, and your context. It will ask for missing details, render the scoring table, and explain what decision the output should change.
Apply Weighted Shortest Job First (WSJF) to my situation. Context: [Decision, audience, options, evidence, and constraints.] Use the Weighted Shortest Job First (WSJF) structure: - Items: - criteria: - scores: - formula: - rank: Ask only for missing inputs that would change the output. Then render the scoring table and name the decision it should change.
how to use it
Use the framework to change a decision, not to fill a worksheet. Start narrow, add evidence, then inspect what the weighted shortest job first (wsjf) worksheet / visual makes clearer.
Write the concrete prioritization choice, tradeoff, or conversation the framework should change.
Fill the important slots: Items, criteria, scores, formula.
Mark what is measured, what comes from customers, and what is still judgment.
End with the next move, the riskiest assumption, or the evidence that would change the weighted shortest job first (wsjf) worksheet / visual.
quality check
Use this check after the artifact is filled. Blank fields are not failure; they are the next research question. Look for concrete evidence, missing constraints, and assumptions that would change the next move.
The framework needs a concrete decision. Broad intent turns it into a worksheet, not a decision aid.
Good framework output makes assumptions visible enough for someone else to challenge.
The diagram is useful only if it changes the next product conversation.
common mistakes
Do not use Weighted Shortest Job First (WSJF) as a worksheet. Name the choice, conversation, or tradeoff the output should change.
Separate measured facts, customer evidence, and leadership judgment so weak assumptions stay visible.
If the diagram does not match the decision, switch frameworks instead of stretching the boxes.
The framework should clarify the next move. It should not replace strategy, sequencing, or judgment.

faq
Sequence work by cost of delay divided by job duration/size.
Business context; objectives; available evidence; stakeholder judgment
Weighted Shortest Job First (WSJF) worksheet / visual
Use Weighted Shortest Job First (WSJF) when the decision matches this job: Sequence work by cost of delay divided by job duration/size.
Avoid it when you need Cost of Delay's output instead: Quantify impact of delaying a work item.
It is both: a structure for thinking and a visible scoring table that makes the decision easier to inspect.
A good input names the real decision, uses concrete evidence, and separates facts from assumptions.
Use the weighted shortest job first (wsjf) worksheet / visual to choose the next move, name the riskiest assumption, or decide what evidence would change the call.
Use Cost of Delay when the real output you need is closer to: Quantify impact of delaying a work item.
Yes. Describe your context and Ask PL can ask for missing inputs, render the scoring table, and explain what decision it should change.
