Scenario Planning

Scenario planning is the practice of building two or more versions of a future office layout, headcount, or portfolio, then comparing them against the same data before anyone signs a lease or moves a desk. In workplace terms, a scenario is a draft answer to a specific question, such as what happens to floor 4 if the company adds 120 engineers and moves to three required days on site. Teams use it to avoid the two expensive mistakes in office space planning: paying for space nobody uses, and running out of seats on the busiest day of the week.

What is scenario planning?

A scenario is a complete picture of one possible future: who sits where, how many seats each team gets, what the sharing ratio is, and what it costs. Planning with scenarios means holding several of these pictures side by side and judging them on the same numbers, instead of debating a single proposal until everyone is tired.

The method borrows from financial planning, where teams model base, upside, and downside cases. Applied to the office, the variables are headcount, attendance, seat supply, and lease commitments. A good scenario changes one or two of those at a time so you can see what each lever does on its own.

Where scenario planning fits in workplace strategy

Workplace and real estate teams reach for it whenever a decision is hard to reverse. The common triggers:

The data backs this up as the default way to plan. JLL found that 90% of organizations now apply utilization data to planning decisions, up from 70% in 2025, and CBRE reports that 80% of real estate leaders cite portfolio optimization as a priority. Modeling scenarios is how those two facts turn into a plan, and it sits inside the wider discipline of corporate real estate portfolio management.

Workplace scenarios worth modeling

Most teams test some version of these:

Data inputs behind a reliable scenario

A scenario is only as good as the data under it. Gather these before building anything:

Running a scenario planning exercise

The exercise follows the same shape whether the question is one floor or a global portfolio:

Scenario planning tools shorten steps 2 through 6. Gable Space Planning lets you fork the live floor plan into drafts and compare them side by side with HRIS headcount and 90-day booking averages. The winner publishes straight to the app employees use to book desks, which is the step most spreadsheet plans never reach.

FAQ

How often should workplace teams update scenario plans?

Review the live plan monthly against attendance data and rebuild scenarios whenever a trigger appears: a lease date inside 18 months, a policy change, a reorg, or hiring that exceeds the plan by more than 10%. Most teams run a full planning cycle once or twice a year and smaller restacks in between.

Who should be involved in workplace scenario planning?

The workplace or real estate lead owns the exercise. Finance supplies cost assumptions and signs off on the lease math, people operations supplies headcount and hiring plans, and team leads confirm adjacency needs and attendance patterns. IT and facilities join when a scenario changes AV, access control, furniture, or signage.

What is the difference between scenario planning and forecasting?

Forecasting produces one expected outcome from historical trends, such as projected attendance next quarter. Scenarios lay out several possible futures and test a decision against each one. Forecasts feed scenarios: the attendance forecast becomes an input, and the scenarios show what to do if it holds or misses in either direction.

How many scenarios should a workplace plan include?

Two to four is the usual range. One scenario is a proposal, and more than four blur together and stall the decision. A common set is a base case built on current attendance, a growth case built on the full hiring plan, and a constrained case that assumes a tighter sharing ratio or one fewer floor.

What tools support workplace scenario planning?

Spreadsheets and floor plan PDFs still handle most of it, with the cost of manual re-entry and plans that go stale within weeks. Dedicated space planning software connects the floor plan to HRIS headcount and booking data, so drafts use live numbers and the approved layout publishes directly to the desk booking system.
