Key takeaways
- A scope baseline makes later changes testable.
- Schedule effects belong with each change decision.
- Readiness requires acceptance evidence, not vendor departure.

Turnover plans evolve after inspection, material discovery, vendor feedback, or owner decisions. Change is expected; unattributed change is the control failure. This study focuses on the record connecting each revision to cost, schedule, approval, and readiness.
Research question
Does a documented scope baseline and change log improve a reviewer’s ability to explain ready-date movement and verify that final work matches the latest authorization?
Methodology
The proposed review samples completed turnovers with different durations and vendors. It extracts the baseline task, dependency, estimate, owner, and target date, then maps every later addition, removal, or substitution. Each change is tested for trigger evidence, requester, approver, cost effect, schedule effect, and updated downstream dependencies. Final release evidence is compared with the last approved version.
Evidence and interpretation
General context comes from PMI project-management research, NIST quality resources, HUD healthy-homes resources, EPA indoor-air guidance, OSHA standards, and CPSC safety education. These sources inform dependency, safety, and evidence concepts but do not establish a universal turnover duration.
Limitations
Retrospective records may understate informal changes. Property condition, labor markets, materials, local requirements, and scope complexity limit comparisons. The design does not assess workmanship, lawful habitability, or whether a specific expenditure was commercially optimal.
Source treatment and application
Primary and professional sources were used within their stated remit, while the scoring framework remains an editorial synthesis. Teams can adopt the turnover scope freeze, track unknown causes separately, and review schedule movement by dependency rather than ranking individuals on raw duration.
