Scope and limitations are related, but they serve different purposes:
- Scope defines the boundaries of your work: what you include, what you exclude, and why those boundaries are reasonable.
- Limitations explain what might weaken your conclusions (data quality, assumptions, access constraints, validity threats), and how you mitigate or interpret them.
How to Write Scope
A good scope statement answers:
- System/context: What setting does the thesis cover (company, process, region, time period)?
- Problem variant: Which specific variant are you studying (and which ones are out of scope)?
- Outputs: What deliverables will you produce (model, algorithm, prototype, evaluation)?
- Exclusions: What you explicitly do not address (and why).
How to Write Limitations
Limitations are not excuses. They are part of honest scholarship. A good limitations section:
- states the limitation clearly,
- explains the impact on interpretation (what you can and cannot claim),
- describes mitigation (robustness checks, sensitivity analysis, triangulation, alternative data, careful wording).
Examples
Scope
This thesis studies order picking in a multi-zone warehouse during weekday operations in 2024. We focus on travel time and labor cost in manual picking, and we exclude redesigning the physical layout because the layout is fixed by the facility. The deliverable is a simulation-based evaluation of alternative picking policies and a set of implementable recommendations.
Limitations
The evaluation uses historical order data from a single facility, which may limit generalizability to other warehouses. To mitigate this, we perform sensitivity analysis on key demand parameters and report performance across multiple demand scenarios.
Common Mistakes
- Scope creep: trying to include “just one more” problem variant without changing your timeline or evaluation plan.
- Hidden exclusions: not stating what you are leaving out (the reader will notice).
- Unacknowledged limitations: pretending limitations do not exist instead of managing them transparently.
