This blog page is dedicated to the resources used to estimate software-intensive systems using traditional and agile development methods. The reason for this resource page is the lack of understanding of how to estimate, the urban myths about software estimating, and the fallacies that estimating is not needed, when developing software, in the presence of uncertainty, when spending other peoples money.

Here's my three point estimate paradox: We all know we must estimate with three points (numbers). so we do it, reluctantly None of us actually want to work with (do arithmetic with) the three points we estimate. In a word, three point estimates suck -- not convenient, thus often put aside even if estimated -- and most of all: who among us can do arithmetic with three point estimates? MORE

The best a project manager can do is develop an accurate time estimate for how long it will take to satisfactorily complete the project. Time Estimation Matters. A 2018 study by the Project Management Institute (PMI), in its Pulse of the Profession report, stated that poor time estimating is the root cause for 25 percent of failed projects. Looking into the future to determine how much time it will take complete project tasks allows for an estimation. MORE

Good cost estimation is essential for keeping a project under budget. Many costs can appear over the life cycle of a project, and an accurate estimation method can be the difference between a successful plan and a failed one. Estimation, however, is easier said than done. Cost estimation is the process that takes those factors into account, and calculates a budget that meets the financial commitment necessary for a successful project. An Overview of Cost Estimation.

Estimation is an invaluable tool for anticipating and managing project uncertainties. Accurate project estimates help identify cost and schedule requirements with relative precision, and reduce the risk of running out of time, resources, and budget during a project. But even with years of experience, project managers struggle with accurate project estimates. It’s easier to estimate in ranges because it alleviates the pressure of not meeting a single-point estimate. MORE
Let's talk about the challenges of schedule estimates and three estimating techniques that can help us do a better job with our estimates. Lastly, we'll look at how to respond to future requests for estimates. Challenges With Schedule Estimates. What happens if someone estimates a task to take 10 days when it should only take 5 days. Conversely, what happens when someone estimates a task to take 5 days when it should take 10 days? MORE
Knowing how to estimate project duration can help teams become more efficient and improve on-time and on-budget delivery. . When it comes to project management time estimation, there are a couple of likely scenarios. Why is it important to estimate project duration? MORE
Importantly, we have to be able to do that without redirecting the whole org to create an estimate. We have to get good at taking ambiguous requirements and translating them into chunks that we can meaningfully size, even though we have very little info — rapid estimation. Some organizations deal with this by disrupting current work to pull bunches of people into estimating these big chunks of work. Sometimes I’ll call this rapid estimation a SWAG. MORE
Poor estimates are often a major factor in these projects. So, let's look at 7 ways to improve project estimates. Define the project work One of the top reasons for poor estimates is poor project definition. Have the subject matter experts estimate the work. MORE
What is a ROM estimate used for? A rough order of magnitude estimate is used to give you a very high level view of potential project costs. But in reality, we rarely have the time or luxury of being able to provide that level of estimate at the earliest stage of project. MORE
