The Trap of Underestimating Project Scope

The conversation usually goes something like this: your preceptor describes an exciting project opportunity, you enthusiastically agree to take it on, and weeks later you realize you have committed to something far more complex and time-consuming than you imagined. You are now either scrambling to deliver or renegotiating expectations that should have been clearer from the start.

This pattern repeats constantly in practicum experiences because students lack the experience to accurately assess project scope, and supervisors often underestimate the time required for someone learning while doing.

Why Scope Underestimation Happens

Several cognitive and situational factors contribute to chronic underestimation of project requirements.

Optimism bias affects everyone. Humans consistently believe tasks will take less time than they actually do. This planning fallacy, well-documented in psychological research, leads us to imagine best-case scenarios rather than realistic ones. We picture everything going smoothly and forget to account for inevitable obstacles.

Unfamiliarity masks complexity. When you have never done something before, you cannot accurately imagine all the steps involved. Creating an educational brochure sounds simple until you discover it requires content research, stakeholder review, design software proficiency, printing coordination, and distribution planning. Each hidden step adds hours.

Enthusiasm clouds judgment. Exciting opportunities trigger emotional responses that override analytical thinking. In your eagerness to say yes, you may not pause to carefully consider what you are agreeing to do.

Supervisors forget learning curves. Your preceptor might estimate how long a task would take them, forgetting that you lack their experience, relationships, and organizational knowledge. A task that takes them two hours might take you ten as you learn systems, seek guidance, and correct mistakes.

The Decomposition Method

The most reliable technique for accurate scope assessment is systematic decomposition: breaking a project into its smallest constituent tasks and estimating each independently.

Start with the end deliverable. What exactly will you produce? A report? A training presentation? An event? Be specific about the tangible output expected.

Work backwards through required steps. What must happen before that deliverable can be complete? List every task, no matter how small. Include meetings, email coordination, research, drafts, reviews, revisions, and final production.

Estimate each task separately. Assign hour estimates to individual tasks rather than to the project as a whole. This granular approach reveals time requirements that aggregate estimates obscure.

Add contingency time. After summing your task estimates, add twenty-five to fifty percent for unexpected complications. This buffer is not pessimism; it is realism based on how projects actually unfold.

Compare total to available time. Does your estimate fit within your practicum hours and timeline? If the project requires more time than you have, you know before committing that scope adjustments are necessary.

Questions to Ask Before Committing

When your preceptor proposes a project, gather information before agreeing to take it on.

What does the final deliverable look like? Ask for examples of similar past work. Seeing a concrete product helps you understand what you are working toward.

Who are the stakeholders involved? More stakeholders means more coordination, review cycles, and potential delays. Understanding the human complexity helps estimate time requirements.

What resources and support are available? Will you have access to templates, previous work, or colleagues who can help? Or are you building everything from scratch?

What is the timeline expectation? When does this need to be complete? Is that deadline firm or flexible?

What happens if the project takes longer than expected? Understanding contingency plans helps you assess risk and negotiate realistic commitments.

Renegotiating Scope Mid-Project

Even with careful assessment, you may find yourself overcommitted. When this happens, address it directly rather than suffering silently.

Raise concerns early. The sooner you communicate that a project is larger than expected, the more options exist for adjustment. Waiting until deadlines loom limits everyone's flexibility.

Propose specific solutions. Rather than simply stating the problem, suggest alternatives. Could the scope be reduced? Could the timeline extend? Could someone else handle certain components?

Document your work to date. Show what you have accomplished and what remains. This concrete information helps supervisors understand the situation and make informed decisions about adjustments.

Accurate scope assessment is a skill that develops with experience. Each project teaches you something about realistic estimation. Pay attention to where your predictions diverge from reality, and incorporate those lessons into future assessments.
