scope creep | Dagny Evans

In my last post, I introduced scope. I defined it, explained how it can go wrong, and discussed the key role of the project manager to manage it. This week, I’m going to dive into some thoughts on scope definition and estimates. With everything I said last week about scope needing constant supervision and management, how is it possible to effectively define project scope?

There is a reason that we refer to the assignment of hours to tasks in projects as estimates. They are rough calculation, or less eloquently referred to as guesses. There are too many unknowns in software or data integration projects to be 100% correct, 100% of the time. However, there are definitely tips and tricks that we can use to get us a point where we are right more often than wrong (although that is a relative number when you consider that scope creep or changes are to be expected).

So, where do we start? We start with gathering as much information you we can about the work to be done. In the sales process, there are usually some very high level swag timelines thrown out, with caveats (AKA assumptions) that point to the need to fine-tune the timeline as the sales process continues. The next steps is to think about those tasks as they relate to functions and tasks your organization has done before. While it may not be the exact scenario, you can usually assign a relatively good initial estimate.

A common error in estimating is trying to estimate a task that is too broadly defined. Make sure you create tangible component tasks.

If a requirement is totally new, or you are using new resources, or there are quite a bit of unknowns, you need to take that all into consideration. You should look at similar work and then apply some multiple of time to account for your unknowns. This is where documenting your assumptions becomes critical. Like the scope definition, estimates and their corresponding plans (work breakdown structures, project plans, etc) are all living, breathing documents. They need to be reviewed, updated and acknowledged regularly.

A separate issue in all of this is the alignment of scope to project cost/budget. This are two very different things. When you are scoping a project, it is in your best interest to scope it fully. Do not consider the customer or organization budget in that matter. It is a strategic decision by your organization (sales, executive, etc) to decide what is charged to the customer for what scope. Negotiation of fees and scope will happen. Your goal should still be to stay as close to budget and timelines as you can, but understand that there can be other circumstances in play.

The biggest take-away to all of this is, you have to start somewhere! Monitor your estimates, update and communicate regularly and then learn from it. Apply the learnings to the next estimates you need to do.

The Project Management Book of Knowledge defines scope as the project boundaries. I prefer this definition on TechTarget:

Project scope is the part of project planning that involves determining and documenting a list of specific project goals, deliverables, tasks, costs and deadlines.

From a practical project management perspective, what does this really mean? Who gets to define this? How do you manage? Let’s delve into the details of a scope.

A very simple evolution of a project is sales > implementation > support. Scope is relevant in each of these phases, however it may not mean the same thing to the stakeholders key to each phase. A company agrees to invest money in a project to solve a business problem. A salesperson has convinced the company that they have the solution. Here’s the first step of the process where scope can diverge. Can the corporate decision maker speak for all the business stakeholders? Do they really understand the details of the business problem that needs to be solved for each type of user? And how about the sales person? Do they really understand the software? Do they understand the business problems it can solve? Are more technical sales engineers involved in the sales process?

That simple example involving just the corporate decision maker and the sales person is indicative of how scope can rapidly become a problem in a project.

Scope must be managed throughout the entire project.

Over the course of my career, I have had different levels of involvement in the sales process. Some I was involved from the first demo/sales call with the customer, others I help with preparing estimates and potential timelines, others I inherit after the contract is signed and others I inherit long after the implementation. It doesn’t matter at what point I become involved in a project, my first action is to receive a copy of all project artifacts. And yes, I do read that contract. I want and need to know what was committed.

Unfortunately, I’m not done there. I take the details I can find in the contract and communicate those out as often as I can. If this is a large project with multiple business teams, I will review the scope with each team. This is the opportunity for your customer, and more specifically the business users, to vocalize their agreement (or not). Either is fine, but it is imperative to align expectations. If there is disagreement, it is the responsibility of the project manager to sound the alarm to the corporate decision makers, and the services and sales organizations. Misaligned scope results in 1) unhappy customers, 2) stalemate of customer and company or 3) mutual agreement to realign scope. Note: The scope doesn’t necessarily have to be immediately changed. It is sufficient for the new work to be phased in after the initial scope implementation.

This is definitely a rinse and repeat process. Business are changing on a daily business, and implementing data and software projects means your environment is constantly changing. Time doesn’t stand still during implementation projects. This means new inquiries and requests come up constantly. Each time, you need to figure out how it fits into the work you are already doing. Some requests can be easily accommodated, but others need a deliberate approach to determine how it impacts existing goals, timelines, budgets, and overall commitments.

Do not fear the scope. The scope is your friend. It provides guiding principles for the work you are doing, and the goals you are accomplishing.
