Let’s build an airport

Once again a talk I held. This time it is quite a long time ago that I talked about estimating large scale products on UX Camp West 2016 in Cologne. Two weeks ago I repeated the talk in an internal meeting at McCann. And I remembered that I still wanted to blog about it.
So here we go. The first thing: why do I talk about large scale projects? Because estimating is always rough and inherits a lot of insecurity. The larger a project is the less important becomes estimating one item wrong. Basically, estimating large projects accurately is much easier then small ones.
So why do we estimate a project?
- We want to plan timings, workload and staffing.
- We need to allocate a budget
- We get some kind of raw concept
And getting there requires three simple steps:
- Gather all information about the project using any tool your familiar with. From a UX perspective this could be brief, vision, personas, scenarios, customer journeys, etc.
- Define the tasks that need to done. First the high level tasks (I know this is wrong, but I call those epics). And when that is done, break down those tasks to smaller manageable ones (again wrong: stories). Those stories should be possible to do in less than 5 days.
- Go through the stories and assign a complexitity and effort measurement. I usually use small, medium and high.
One thing is really important to me: you should always estimate collaboratively.
I have created an Excel workbook that can help you with the estimation. Feel free to use it.
