Software cost modeling example




















Understanding the type of project is the first step in developing a cost estimate. This information will be used in combination with the size of the project and the project team to determine the final estimate.

The next step is to determine the size of a project. Size is a bit of a gut call. Generally, project sizes fall into the following categories:. Typically, things like tweaks to the user interface or bug fixes that are well defined with a known cause.

Interaction with the client is limited, i. Typically, we are dealing with a single source of data. Projects such as a small mobile application or a web interface to an existing inventory system would fall into this category. The external requirements for interaction with a client are more robust than small projects. This might include a few design sessions, weekly check-ins, and milestone sign-offs. Large projects may require integration with multiple systems, have a database component, and address security and logging features.

An underlying framework and a module-based design are common, taking into consideration scalability and maintainability. A multi-party application that works across numerous platforms iOS, Android, Web would fall into this category.

The external requirements for interaction with the client are very robust, i. Daily calls and interactions with technical team members followed by weekly status calls with higher-level management are standard. Enterprise-level projects are almost exclusively built upon an underlying framework. They have much more rigorous security, logging, and error handling.

Data integrity and security are paramount to these business-critical applications. Though not exclusive to this category, support systems are built to be resilient and able to handle concurrent faults in the underlying infrastructure before having a user impact.

A mobile app like Uber would be an example. The external requirements for interaction with the client involve fully-integrated client and IT teams.

Now that project types and sizes are defined, they can be combined to put together the following possible timeframes:. Sales and Delivery can now give a quick estimate to clients regarding how long a project will take. Once the project is defined in terms of type and size, the next factor to be determined is the team size. However, that does not mean that every role equates to one team resource.

Some resources can fulfill more than one role. For example, In a small project, a Developer may also fill the role of Tester. For larger, complex projects — team resources usually fulfill only one role to effectively move the project forward. Rough estimates of team sizes may include the following structural roles:. Unfortunately, it is not that easy. As mentioned earlier, some resources may play more than 1 role on a project. They may be needed to confirm coding is meeting design requirements, or be available to tweak the design, but full-time is no longer necessary.

Insight: 4 cost models you can create with cost estimating software. It seems like it happens because of the little things that appear during the development of the project, but in fact, we could have discovered and taken them into account in advance.

The article contains simple and, at the same time, useful recommendations as well as a method for calculating software costs. This will come in handy to a project manager, architect, system analyst, IT solution seller, and everyone else involved in estimating software development cost of fixed format. We will only focus on how to calculate software development cost, estimating the duration is a completely different story.

I am going to describe my personal experience of how to estimate the cost of a software project, and, of course, you can have other situations and your own methods. The vast majority of projects on the market are projects completed based on a fixed price cooperation when the budget and terms are planned in advance, at the stage of sealing the deal.

Need to scale up the development? It is clear that the client is the only one to blame. There is also another factor — the variety of projects, systems and technologies, and the lack of qualified specialists. This means that when planning a project, the architect or project manager may not take into account that they can get a specialist on the team who has not previously performed such tasks or somebody with insufficient qualifications.

Surely, in this case, the performance will be lower than expected. The client wants to know the exact figures for the cost and deadline of the project before signing the contract.

For instance, there are user requirements for viewing certain data. The team identified what tasks needed to be completed and estimated the total amount of work at 56 hours, breaking them down as follows:.

But as the matter of fact, these tasks have basic functionality — creating tables in the database, storing procedures or views for selection, creating business objects, connecting them to the security module, connecting to the logging module, configuration, and so on. At the same time, the seller, who is discussing the work on the project, has nothing to say.

On the other hand, the entire volume cannot be reached in 24 hours. How to calculate software costs in such a situation? I recommend highlighting the basic functionality. This will allow the seller to behave more correctly. By removing unnecessary features, there will still be sufficient development time. A detailed analysis of the requirements, the composition of a technical task, and a more or less clear area of work on the project occur after the signing of the contract.

Demonstrations should be carried out not only for business clients but also for employees of other customer departments potentially involved in the project system administrators, key users, security service, etc. This will allow receiving comments in the early stages, discuss problems, and allow the user to get used to the interface and functionality.

Solution: we include the cost of creating documentation in the software development cost calculator. If the project team is formed anew, there is a risk that the qualifications of one or another specialist may be lower than expected. Solution: when calculating how much does it cost to have software developed, planning tasks, and time for their implementation, it is necessary to focus on specialists at a level lower than expected to be involved in the project.

IT technologies and tasks are becoming more and more complex, which makes it more difficult to identify the pitfalls of the selected technologies at the early project stages. IT technologies and tasks are becoming more complex. Identifying the pitfalls of selected technologies is not an easy task.
