What Is an Estimation Function and Why Is It Important in Digital Development?

In the world of software development whether it's Web, Mobile App, or backend systems planning is the core driver that keeps a project running smoothly. One of the key tools the Senna Labs team uses to ensure efficient workflow is the Estimation Function.

So, what exactly is the Estimation Function? How does it help? And why is it so essential for both the team and the client? Let’s take a look.

What Is an Estimation Function?

An Estimation Function is the process of evaluating the cost, effort, and duration required to complete a specific feature. It helps forecast the complexity, development time, and resources needed for each part of the project whether it’s an application feature, a website page, or backend functionality.

At Senna Labs, we apply the Estimation Function throughout our Agile Project Management process, especially during Sprint Planning and Sprint Grooming, ensuring each sprint is clear, trackable, and less prone to delays or budget overruns.

Why Is the Estimation Function Important?

1. Accurate Prediction of Time and Resources

It enables the team to efficiently plan and allocate resources knowing how many days and how many people are required for any given task.

2. Improves Communication With Clients

Clients receive clear insights into how long a feature will take and how complex it is. This helps them make faster and more informed decisions.

3. Better Risk Management

Careful estimation from the start reduces the likelihood of delays, over-consumption of resources, or deliverables that don’t meet expectations.

How Senna Labs Performs Estimation

We use Relative Estimation methods, such as:

• Story Points
  
  

• T-Shirt Sizes
  
  

• Planning Poker
  
  

Developers, QA, UX/UI designers, and PMs collaborate using real-world experience to generate reliable estimations.

We also integrate the Estimation Function into our internal Toolings platform, a project management tool that enables us to define scope, track progress, and calculate costs in realtime.

Estimation Function and Work Transparency

One of Senna Labs’ key strengths is transparent collaboration with clients. Accurate estimation allows us to continuously update progress and proactively flag any potential issues during development.

Conclusion

The Estimation Function is the foundation of effective planning in Agile. It enables faster, higher-quality, and more predictable digital project delivery values that Senna Labs consistently upholds to ensure our clients receive the best possible results.
