A Complete Overview of Converting Story Points to Hours

If you have worked in project management, you may have noticed that estimating time of completion of a task is vital to overall project success. In my experience, this estimation is not always straightforward. In an Agile project management, we encounter many risks and unknowns. These need to be factored in when providing an estimate of the efforts. 

This is where the concept of story points comes to the fore. 

In this blog, I will take you through the concept and explain it better. This insight will help you benefit from this aspect of Agile time management.

What are Story Points?

These are units of measure used in project management to determine how hard a task is. They help assess and compare tasks based on the effort expected to finish them. This unit considers things like-

• How complex the task is

• What amount of time could it require

• The resources required

They are typically assigned using a modified Fibonacci sequence (1, 2, 3, 5, 8, or 13, etc.). The number reflects the inherent uncertainty in estimating larger, more complex items. Unlike time-based estimates, this unit of effort measurement takes into account many variables. These include the complexity and likely risks in implementing a feature.

Teams use story points during sprint planning. They utilize it to figure out how much work they can commit to in a given sprint, based on their historical velocity. Over time, the teams become more familiar with their capacity and estimation accuracy. With this progress, story points help create more predictable sprint outcomes.

The Role of Story Points and Hours 

Allow me to explain the value of hours in the conventional project management framework. It will show the impact they have on project success.

1. Work Breakdown Structure

The WBS is a crucial tool used in the project planning process. Here, the team divides the project into parts or phases that team members can easily handle. They allocate an estimated number of hours to every task or activity in the WBS. This number indicates how long it will take to accomplish the task. This estimation is important. It determines the feasibility of the planned project timelines.

2. Gantt Charts

These tools are highly effective and commonly used in traditional project management to represent the schedule. They represent a work against time. This enables the project manager to see how long each activity will take and how they are linked. Proper estimation of hours ensures that the Gantt chart represents a realistic time scale.

3. Assigning Tasks

In project management, the manager will allocate work to a team member as per their workload. This way, he can spread the workload among the team. In parallel, he can avoid overload for all the team members.

4. Balancing Workload

The timely distribution of work and its equitable sharing is the key to efficient work and high spirits. If time is tracked, project managers can see if any team member is overworked or not utilized. This makes them work under a plan with checks and balances. Such a method makes certain that they are on track to complete the project.

5. Progress Tracking

Keeping work hours records enables project managers to assess the completion rate against the plan. This type of check gives a more accurate picture of what the team has accomplished and what they still need to work on. The insight gives the management a heads-up when the project goes off track and requires assistance.

6. Variance Analysis

This type of data crunching compares the planned hours with the actual hours spent. The analysis helps identify discrepancies and understand their reasons, such as- 

• Underestimating task complexity 

• Unforeseen issues 

This enables better future planning.

Benefits of Using Story Points

Below are a few other significant advantages of using this unit of measurement for estimating the effort needed for completing a user story.

1. Create consensus and partnership 

If one colleague estimates 5 story points while another estimates 12, it is a chance for the team to talk about the tasks and understand the work involved.

It could be that one of us knows a better way of doing it and the other may just have a clearer understanding of the steps. Discussing this allows them to share the information and come up with better estimates.

As members negotiate and agree on story point values, they build trust and alignment. This consensus-driven approach improves estimation accuracy. At the same time, it strengthens team cohesion and project ownership.

2. Balancing Accuracy and Practicality

Story points assist with estimating your team’s achievable tasks within a particular timeframe. This precision drives smoother releases that adhere to plans. It is especially beneficial when dealing with multiple teams and many influencing variables.

However, this unit also stresses on the fact that these estimates are not exact commitments to finishing X amount of work in Y hours. It is difficult to state the number of hours in advance because the work may encounter various problems and obstacles.

Other methods may offer more precise time estimates. But it is not viable to discuss every story in your backlog for 30 to 40 minutes. It is more productive to make a rough estimate and get started with work.

3. Improved planning for workload

It is often challenging to include all your goals in a release, particularly if they are difficult or take a lot of time. Story points can help by allowing you to easily pick a few smaller tasks to fill your team’s workload each sprint or release.

Using story points also encourages you to boost your team’s capacity without needing them to work longer hours. You can handle more tasks more efficiently by reducing risks and involving the right people for complex tasks.

When and Why Convert Story Points to Hours?

We should use story points when working on Agile projects because they benefit the team. Here is when you can convert agile story points to hours.

1. Initial Planning and Estimation: You can use data from previous sprints in effort estimation. Doing so will help you understand the average number of hours a story point typically represents. This can help you determine how much time the entire project might take.

2. Sprint Planning: You can convert story points to hours for optimal allocation of resources. This step makes sure the team members are not overburdened by workload. 

3. Tracking Progress and Performance: You can convert story points to hours during retrospectives. This will help to analyze differences and improve future analyses.

Why Convert Story Points to Hours?

The following are a few reasons why converting story points to hours can be helpful. 

1. Tracking progress: Teams can use story points to monitor how far the project has reached. Let us assume a task is estimated at 100 story points. This unit helps examine how many points are completed. This way each sprint meeting shows how much work is finished.

2. Setting budgets: Converting story points to hours or days can help with budgeting. It assists teams with estimating the costs of completing a project.

3. Estimating project timelines: The story points measure effort, not time. Converting them to hours or days can facilitate the estimation of the project’s length.

Step-by-Step Guide to Converting Story Points to Hours

Converting the story points to hours tends to be challenging since it is not exact. The conversion variable can vary among teams depending on their past performance. However, you can begin with these guidelines for estimating story points in hours.

1. Understand the Velocity of Your Team:  Velocity in Scrum indicates the number of story points a team can complete within a particular time span, generally measured in sprints. To track down this specific data, you should examine past sprints. For example, if your team reliably finishes 30 story points in a 2-week sprint, then your velocity is 30 story points.

2. Estimate in Hours: To convert story points to hours, you should predict how many hours each story point represents for your team. This is done by noting the time taken to complete tasks, with various story point values.

For instance, let us consider these situations-

• A 3-story task may need 15 hours for completion
• A 6-story task takes 30 hours

In such a case, you can estimate that every story point would come to nearly 5 hours.

3. Apply the Conversion Factor: You would come to know how many hours each story point represents on average. Now, you can use this number to convert story points into hours. For instance, a task is estimated at ten story points. In this scenario, you can assume that it will take around forty hours to complete (10 story points multiplied by 4 hours per story point).

Remember that this is a rough estimate and may not be exact. However, while converting story points to hours, it’s vital to stay adaptable and update your estimates as you gather more data and learn from your team’s performance. The conversion factor from story points to hours might evolve as your team acquires experience.

Common Challenges in Conversion of Story Points to Hours

Here are the common difficulties in transforming Story Points to Hours.

1. Misuse for Individual Performance Evaluation: Teams may incorrectly use story points to estimate individual productivity or performance.

2. Over-Detailing Timelines and Resources: There is a temptation to use story points to create detailed timelines and resource allocation. This isn’t their intended purpose.

3. Improper Task Prioritization: Teams may struggle to use story points effectively to prioritize tasks based on complexity and required effort.

4. Assigning Story Points to Bugs: There’s a tendency to assign story points to bug fixes inappropriately. This can skew sprint planning.

5. Overemphasis on Unanswered Questions: Teams might focus too much on open questions. This overlooks other essential aspects of the task.

Conclusion

Story points enable flexibility in your agile project management. The conversion of hours into story points will have better outcomes. Striking a balance between these two metrics guarantees effective planning. With this approach, teams can utilize the strengths of the agile methodologies. Overall, understanding conversion of story points to hours is crucial to cater to diverse project necessities.
