What is the WSJF prioritization?

WSJF, standing for Weighted Shortest Job First, is a prioritization model utilized in the Scaled Agile Framework (SAFe) to balance the urgency, value, and cost of development tasks. This method aims to prioritize tasks based on a cost-benefit analysis, thus helping organizations deliver the maximum value in the shortest possible time.

Additionally, each feature or task is weighted according to its value, risk, time criticality, and opportunity enablement in WSJF. These parameters form the numerator of the equation, called the ‘Cost of delay.’ The denominator, ‘Job Size’ or ‘Duration,’ represents the effort required to complete the task.

  • Cost of delay: It signifies the potential loss incurred due to the delay in delivering a job. This is a pivotal concept in WSJF, driving the importance of early value delivery. The cost of delay comprises:
  • Business value: It is the direct value the task will contribute to the business or customers.
  • Time criticality: This factor considers whether delaying the task could result in missed opportunities or cause problems.
  • Risk reduction/Opportunity enablement: These are the strategic values that the task could offer in terms of risk mitigation or the creation of future opportunities.
  • Job size: It is an estimation of the effort needed to complete the task. A smaller job size is considered preferable as it delivers value quicker.

By dividing the cost of delay by the job size, WSJF prioritization gives an economic view of each task, highlighting those that deliver the most value for the least amount of effort.

Benefits of using WSJF

WSJF prioritization provides several significant benefits for teams and organizations, particularly in software development and project management.

Maximization of economic benefit

WSJF helps to deliver the maximum economic benefit to the organization. Prioritizing tasks based on their value, risk, time criticality, and effort required, ensures that the most beneficial tasks are addressed first.

Improved efficiency

WSJF aids in reducing the amount of work in progress (WIP) and shortens the cycle time by prioritizing smaller, high-value jobs. This can lead to a significant increase in productivity and efficiency.

Transparency and objectivity

Using a mathematical prioritization model, WSJF introduces transparency and objectivity to the decision-making process. As a result, this can help to reduce biases, enhance team communication and agreement on priorities, and improve stakeholders’ understanding of decisions.

Strategic alignment in WSJF

WSJF enables the alignment of work priorities with the strategic goals of the organization. This ensures that the work done is not just efficient but also effective in meeting the organization’s objectives.

Effective risk management

Including risk as a factor in the WSJF model allows teams to better manage and mitigate risk. By considering the potential risk reduction or opportunity enablement of tasks, teams can prioritize those that reduce high risks or create significant opportunities.

Data-driven decision making

WSJF promotes data-driven decision-making. Rather than relying on intuition or subjective judgments, this prioritization is based on quantifiable measures, leading to better, more informed decisions.

Limitations and considerations of WSJF

Despite its advantages, the Weighted Shortest Job First is not without its challenges.

Estimating job size and quantifying value, risk, and time criticality can be complex and may require a degree of subjectivity. Moreover, WSJF does not consider dependencies between tasks, which can impact the prioritization process.

Therefore, while it offers a powerful prioritization tool, it should be used with other decision-making practices for the best results.

Other prioritization methods for optimizing your project management

As mentioned, the WSJF is not the only method you can use to prioritize and manage your projects. Other popular prioritization frameworks are the RICE framework, the Value vs Effort matrix, the MoSCoW method, Kano, and more.

Although each has its own advantages and disadvantages, you may find yourself using different methods at different stages of the project. The decision depends on how you and your team work and communicate, and it can also depend on the project itself.

Nonetheless, you can also try combining different prioritizing methods. There is no rule telling you not to do that, so why not give it a try? Perhaps you can find even better results than just using a sole method.

Final thoughts

The WSJF prioritization method is undoubtedly one of the best ways to help you manage projects effectively, especially in the agile environment. It is not just a recommendation, these value-driven development methodologies are a must to keep your workflow smooth.

Don’t forget, you are not bound to only one method. You can combine the best prioritization techniques to get the best results possible.And if you’re looking for a prioritization tool for Jira, Routemap will be an excellent option you must try.

FAQs

What is the Wsjf in simple terms? ›

Weighted Shortest Job First (WSJF) is a tool used in the Scaled Agile Framework (SAFe) to help teams prioritize a list of initiatives. A team calculates each initiative's score as the cost of delay divided by the job's size or duration. The team then prioritizes those items that receive the highest ratings.

What is the Wsjf method in Agile? ›

Weighted Shortest Job First (WSJF) is a prioritization model used to sequence work for maximum economic benefit. In SAFe, WSJF is estimated as the relative cost of delay divided by the relative job duration. In a flow-based system, priorities must be continuously updated to provide the best economic outcomes.

What is the benefit of WSJF? ›

By evaluating factors like business value, time criticality, and risk reduction, WSJF ensures that the most impactful features start generating value as quickly as possible, enhancing efficiency in Agile environments.

What is the WSJF priority score? ›

WSJF score: This is typically a numeric value calculated using the cost of delay and job duration metric for each task. The higher the value, the higher the task's priority, and vice-versa.

What is the formula for WSJF calculation? ›

Joshua uses the same formula as Reinertsen to calculate WSJF: cost of delay divided by duration, which he termed CD3.

What is the downside of WSJF? ›

Cons of WSJF

If a product owner or a product manager has hundreds of backlog items (e.g. for a mature product), then they have to spend significant time to prioritize them using this method. It also takes time to estimate the values (albeit relative) for each of the components of WSJF.

What are the alternatives to WSJF? ›

The Eisenhower matrix and Value vs. Effort matrix are all good alternatives to WSJF model, which will allow you to quickly prioritize features in different categories.

What is the user value of WSJF? ›

The formula for WSJF is (User Value+OERR (Risk Reduction|Opportunity Value)+Time Value)/Job Size. If the team's job size estimates are updated to include only time remaining, then constant application of WSJF ignores sunk costs, which are a key economic principle of lean.

What is true about WSJF? ›

Explanation: The correct statement about Weighted Shortest Job First (WSJF) is b. The item with the highest Cost of Delay is prioritized first. WSJF is a prioritization model used in Agile software development to sequence jobs (for example, features, capabilities, and epics).

What is the range of WSJF? ›

The Calculation

The duration is between 1 and 20, so the overall WSJF ratio will range between 0.15 and 60, with the higher number indicating a higher priority. This is still (just) a guide for the product professional to use and they make the final decision on sequencing.

What is time criticality in WSJF? ›

User / Business Value ranks your jobs by their relative importance to the user and potential impact on revenue. Time Criticality ranks the jobs by urgency: how the value will decay over time or how many customers we may lose if we linger.

Are features prioritized using WSJF? ›

WSJF is a strategy for prioritizing the implementations of product features according to their weight (i.e., their numerical value of importance calculated by stakeholders) divided by the effort (the length of a job).

What is an example of WSJF in Agile? ›

WSJF in Agile works on the principle that the task of the highest value and the shortest duration should be completed first. For example, it is better to do 12 one-month-long projects than a 12-month project since the former will add more value.

What is one key to leading a successful change? ›

Effective communication

Effective communication not only helps people understand change and how it will impact them, but also keeps change efforts on track. When the communication is two-way, individuals also have opportunities to share feedback and ask questions.
