Every client desires to have financial and software development time estimation early on. So, the client can decide the financial implication and time frame of completing an intended project. Likewise, how small or simple the software time estimation project could be is one of the critical aspects.
Software project estimation often exceeds time estimation, resulting in an enlarged budget, missed market opportunities, and penalties due to Service Level Agreement. However, such outcomes are avoidable, but project managers should have a structured approach toward software time estimation to avoid it.
Nonetheless, here we share some of the techniques that help manage software development time estimation better, so you give the right software development life cycle time estimation to your clients.
Below are some software development time estimation techniques that will help you accurately estimate man-hours for a software project.
Take your software project’s complexity seriously and understand the level of risk involved with that software development, as it can heavily affect the duration. Likewise, it’s recommended that you divide projects into three parts, namely:
Developing software with specific predictable requirements, such as a primary customer portal for a small company. Henceforth, the estimation will be predictable and accurate, while the involved risk will be the lowest.
A software project with its core predictable but has specific requirements in addition. For example, developing a customer portal but also integrating ERP. Therefore, small risks are probable at the time of integration.
Suppose there’s a software development project involving specific technology or innovation and uncertainty in business requirements such as developing software on Agile techniques. In that case, such software projects have higher risks. Likewise, there can’t be an exact time estimation as well.
Therefore, figuring out the complexity of the software project helps the company tremendously as you can defend how much time should be dedicated to the project and how much risk will be involved.
Before you make a detailed software project estimation, your customer may want to know a rough estimation, to form an expectation. Henceforth, once you identify software complexity, it’s recommended that you make a rough estimation based on your earlier software development experience and make your client aware of it. For example, you can give an approximate idea that it’ll take around six months for two developer teams with five people to complete the project.
For detailed software project estimation, it’s recommended that you build the scope of work that shows the exact requirement of the software and then evaluate each requirement. In addition, ensure what software development techniques you’re using in your project.
Traditional practices involve underlying requirements that don’t change so quickly. Henceforth, it’s recommended that you break down the requirements into small and easy to estimate tasks. For instance, using Work Breakdown Structure, a tree structure that shows you the phase of software development related to each task.
Once you complete all the processes, you can start the time estimation of each task using the two below-mentioned methods:
The Wideband Delphi is an estimation method that uses consensus-based techniques for estimating the tasks. Likewise, it compares results and raises or negotiates each task-related concern.
It’s the data-driven estimation based on similar activities of your previous projects. So, for instance, if you go through the estimation and real-time spent on earlier projects doesn’t coincide, you’ll be able to know which activities are riskier according to the timeline. Henceforth, you can give more time and management effort to that task.
The precise time needed for the development is enough for smaller projects. And, for more significant Waterfall projects, it’s recommended to go minimum to the maximum time needed for each task—for example, WBS (Work Breakdown Structure). So, you’ll be able to make sure issues don’t alter your project development flow.
In this method scope of the work changes once any change occurs in the requirement. Likewise, the workload is based on the value of end-users. It means the more value a feature it provides, the sooner it’ll be developed. Likewise, the planned tasks are shown in the backlog according to the priority.
Furthermore, it’s recommended that it’s better to estimate efforts instead of the time when it comes to Agile projects. And you can also point out the effort consumption of units for the user. In addition, it’s recommended:
You should add an overall risk buffer between 5 to 25% of the overall project depending on the complexity of the project depending upon common risk factors like:
Always have around 20% of a project time for time eaters such as team meetings, productivity drops, communication gaps, etc.
For instance, you can make use of the below formula:
The project overall has an estimation of task time of 8200 hours overall. Hereafter you can:
8200 + 8200 * 0.25 + 8200 * 0.20 = 11890 Total hours needed.
This method is quite similar to analogy, but it offers more accuracy. It involves statistical or mathematical steps such as:
It’s another software time estimation where three ranges of estimation from three different data points are provided. The three points are namely best scenario, likely scenario, and worst scenario. And the final estimation is the average of the estimates.
Furthermore, this three-point estimation has the advantage of reducing the chances of an inflated estimate. It’s also among the simple yet effective software development and cost estimation methods.
In the bottom-up estimation technique, the software project is divided into several tasks and sub-tasks, which can be managed and tackled easily. Henceforth, it becomes easier to manage software development time estimation. Likewise, task estimation should be separate, and the overall total from the bottom to top should be again calculated for final estimation.
Though it takes more time for estimation, it also gives a more accurate estimation by considering every component in detail.
Many times people confuse software time estimation with the amount of funding. It’s a little similar but vary from each other. For example, software development time estimation involves the timing needed for completing the software project. Likewise, it becomes budget later once the owner of the software project approves it. And, after such approval, funding gets allocated.
Furthermore, estimation is helpful for the production and management of the software project. It helps calculate the resources, efforts, cost, and time involved to complete the software and deliver the project successfully.
And as the client, you should know that software time estimation has nothing to do with the final cost of the software project, but it just gives a basic idea about it. And the main intention behind the software development life cycle time estimation is to let the customer know about the budget and stay prepared about it.
Furthermore, standard software development time estimation is transparent, and it’s provided typically in a below-mentioned way:
Below are some benefits you can expect by estimating software project completion:
Nonetheless, software time estimation shouldn’t hinder other business things, and you are expected to rely on business needs most of the time. However, if there’s a lucrative market opportunity with limited time, you can use some of the software time estimation techniques mentioned here.
