Scope creep
Incremental expansion of work beyond the agreed scope without a corresponding change to
price or timeline.
Usually a documentation failure rather than a client failure: scope stated as activities
rather than deliverables has no boundary to cross.
Situation, Complication, ResolutionSCR
A problem-framed business case structure, associated with McKinsey. It establishes
context, names a quantified obstacle, then proposes the specific remedy.
SCR suits a sponsor or investment committee audience, who are evaluating risk and are
persuaded by a cost of inaction. Compare with SOR, which suits an operating audience.
Situation, Opportunity, ResolutionSOR
An opportunity-framed business case structure. It establishes context, frames the upside
against an industry benchmark, then proposes the engagement that captures it.
SOR suits an operating team who already accept the problem and want to know what good
looks like. The same discovery evidence supports either frame; the choice is about the room.
Situation
The opening section of an SOR or SCR: current-state context establishing that the author
understands the business, before any problem or opportunity is named.
A useful test — delete every bullet a competitor could have written from the company
website. What remains is the actual discovery.
Statement of workSOW
The contractual document defining what will be delivered, by when, at what price, and on
what assumptions. It typically operates under a master services agreement.
A statement of work differs from a scope of work: the scope is one section within it. The
statement also carries timeline, commercials, acceptance criteria, assumptions and exclusions.
