The single-case example examines construction of the Jubilee Line and its effects on residents above the London Underground works. The project combined a literature study with more than 5,500 survey responses and about fifteen to twenty interviews, making one infrastructure programme large enough to sustain the whole dissertation. Multiple-case designs work differently by comparing several bridges, retailers, therapies, games, or other bounded subjects. Comparison can reveal differences that a solitary case would leave invisible. The number of cases should match the scale and purpose of the available evidence.

Single-case and comparative case-study designs
A Jubilee Line dissertation shows how one large case can sustain a project when backed by more than 5,500 survey responses and about fifteen to twenty interviews, while smaller cases can be arranged for comparison.
