Web Development – custom web-based software developmentĮach of these types of projects typically has a different team makeup and requires a different amount of development effort. This would include plugins to packages like Office as well as manipulating data flowing between an inventory system like Netsuite with an accounting system like Quickbooks.

Software Integration – Custom code to add capability or integrate existing software into other processes. Software Modification – Enhancement of existing software. New Software Development – new software, involving custom development. Now that we are square on the difference between timeline and effort, let’s look at the 3 factors we use to best gauge our likely effort and thus software cost.įrom a high level, typical software development engagements tend to break down into the following types: These types of issues can exaggerate the difference between effort and timeline – and the longer the timeline extends, the more project management effort is needed to keep everything on track.

Once we know how much effort a project will take in a perfect world, we then have to consider what circumstances outside of our control may come into play.

how many engineers and how many of their hours per day will be required to get the job done. The first part of pricing comes down to how much effort is needed to achieve the desired outcome.

If you are told something will take “3 weeks”, is that 3 weeks from start to finish, or 3 weeks of effort? Now that we have that straight, let’s take a look at how to determine the amount of effort that goes into a project. So, make sure when you get a project quote that it takes into account both effort and time. In both cases, the effort is the same (40 hours of engineering time), but the timelines are different. Or if we ran into external issues, like a client not granting access to a server and waiting for a week before credentials are approved.

Effort is how many hours of work need to go into a project Time is how long something takes from start to finish.įor example, 40 hours of effort can be put forth in 8 hours by having 5 engineers divide the work in one day on a project. Alternately, it could take well over 40 hours to get the same amount of work done if we weren’t able to dedicate an engineer to the project full time. To answer the question of How Much Effort? – we need to make a distinction between effort and time. The first questions typically asked by those looking to have software developed is, “How long will it take and how much will it cost?” But from a pure cost standpoint, that answer is all based on how much effort is required. We’ve been able to identify 3 main components that have the largest effect on project cost and timeline.

That said, we at SphereGen have been helping companies for over a decade and are happy to share a few rules of thumb to use when estimating project cost. These points will clarify the difference between timeline and effort, explore what factors are utilized to come up with an initial estimate, then discuss specific examples of projects with pricing estimates.Įvery engagement is unique and there is no one simple formula that will work for EVERY scenario. Here we outline what goes into estimating the amount of effort and costs of a software development project. Estimates of software development costs can vary and the estimate process is not transparent to customers. Often customers don’t realize the factors that affect the cost of software development. Almost every sales meeting regarding software development revolves around getting answers to these questions.

Two questions define the constraints that most clients experience in project work – “Can I afford this?” and “Can it be done in time to meet my expectations?”. When a company or individual looks to estimate the cost of software development, inevitably questions like “How much?” and “How long?” are asked.
