In this article, we briefly discuss the different SCE models in software application development with proper use of it. As the software industries are very competitive so the software cost estimation process plays an important role in the development process to improve the effort and assumption. The experience-based estimation is the most common estimation model as it is lightweight and easy to implement.

This is a guide to Software Cost Estimation. Here we discuss an introduction of SCE with respective working and applications. You can also go through our other related articles to learn more —.

A common expert judgment model is the Delphi technique , which involves constituting an expert panel, conducting a survey where each expert states their opinion, followed by discussion, and repeating the exercise multiple rounds until all the experts develop a consensus to identify a common cost estimate.

Agile projects rely on the experience of people who actually undertake the work and remain familiar with actual costs, rather than theoretical or boardroom experts detached from the actual operations. Expert judgment methods are grounded in practical realities but remain highly subjective. Success depends wholly on the skills and competence of the experts chosen.

For instance, the cost estimate for a software project with a timeframe of 12 months and personnel requirement of five entails direct calculation of the wages of five people for 12 months. This method, though simple and straightforward, may create unrealistic estimates and may not cover all bases.

This is a practical approach, for ultimately the net cost is what the customer pays, minus profits, and any excess scope or size invariably gets toned down to match customer budgets.

For instance, if a software project was estimated at person-months, it would invariably be toned down to person-months if the customer could afford only that much. On the flip side, this approach does not consider the possibility of projects incurring loss owing to scope creep or any other reason.

Agile methodology means changes in the scope of work due to changes in requirements. The scope of all tasks is divided into sprints, every sprint lasts 2—4 weeks.

It makes sense to start the process with the development of MVP. To measure the effort, you can use story points. For this purpose, poker planning sessions will be a useful tool. In real life, it works like this: if there are 2 story points for one task, and the team needs 48 hours to complete it, 1 story point is equal to 24 hours.

Having, for example, story points, you can multiply that by 24 hours to get an approximate project estimate of about 14, hours. Remember that an estimate is always flexible. In Agile methodology, it is important to evaluate every sprint. When needed, engage the client to suggest new features. Of course, always update your estimates after you come up with any changes or new ideas.

By the way, the Jelvix experts have made an extended material about these methodologies and their differences so you could dive deeper and choose which option is the best fit for your project. Today the market offers many free and paid tools to solve almost any project management problem. We propose you a list of the most common ones, but which one to use is up to you. Probably, you will have to update the estimates for separate tasks or the entire project because you might not have taken into account some of the nuances at the preparation stage.

This is mainly because you might not have addressed all requirements in full. The more details you get from the client, the more accurately you can plan the work without making significant changes.

Constant communication with the client, informing about the progress of work, and feedback from the client are the main factors influencing the success of the project. Close contact will allow you to react as quickly as possible to any changes, and painlessly reallocate resources within the team. In case you were looking for a team that would accomplish any given task in the shortest terms with high quality and reasonable price, you should check out the Jelvix guys!
