Scope Creep

Scope creep is the gradual and uncontrolled expansion of a project's agreed work beyond what was originally specified and priced. It typically occurs through informal requests, small additions, and verbal instructions that are actioned without a written change order or price adjustment. Because each addition appears minor in isolation, the cumulative effect on project margin often goes unrecognized until the job is complete and the final cost is reviewed.

Why Scope Creep Erodes Margin

The mechanism is consistent across industries. A site manager asks an electrical contractor to add a few extra circuits while they are on-site. A client asks an AV integrator to configure an additional meeting room. A furniture dealer is asked to assemble items in a second location that was not in the original spec. Each addition takes an hour or two. None get a written price agreed. None appear on the final invoice.

PMI's Pulse of the Profession research found that 52% of projects experience scope creep or uncontrolled changes. For project-based businesses working at 20-35% gross margins, absorbing two or three hours of unpriced work per job compounds quickly. Twenty jobs per month at two unpriced hours each at a $70 burdened rate removes $2,800 from the bottom line before the month is over.

Controlling Scope Creep with a Written Change Process

The primary control is a written scope in the original accepted quote or order confirmation, combined with a consistent rule that any work outside that scope requires a written change order with an agreed price before it proceeds. This is covered in more detail in the Variation Order glossary entry.

In Zigaflow, works orders and jobs allow additional scope to be logged against the original job record, making it clear what was agreed and what constitutes billable extra work.
