Assumptions Needs Expectations Outcomes

Are assumptions properly thought through and in the open at the

outset?

Are all points of interest properly

represented and resolved?

Are strategic implications and consequences

thought through?

Are user needs made crystal clear?

Are risks and potential

downsides realistically

mapped out?

Are value propositions

clear?

Is usability and manageability

for the occupier properly

resourced?

Are expectations

managed appropriately

and realistically?

Are likely outcomes monitored

against effects of

change and potential

volatility, e.g. for future

adaptability?

Are likely and actual

outcomes evaluated against the

brief requirements?

Are targets met?

Does the building work as intended?

Are user needs met?

What are the lessons for the future?

Brief taking, reality checking, communicating design intent, making sure things work properly, making sure needs are met.

Better management of technology

More modesty, less pretentiousness

So …

• Better briefing. Identify constraints realistically in the brief. Set goals. Learn from outcomes. Targeted briefing. Honest, open feedback.

• More attention to basics. Air tightness, density, reduced demand.

• More emphasis on context. Do a few things very well, suited to the situation.

• Better commissioning. Soft Landings. Widen professional boundaries. A less adversarial approach.

• More attention to reality and less to good intentions.

• More emphasis on users’ needs. Understand dissatisfaction.

• More modesty. less pretentiousness. How buildings learn over time.

• Better management of technology. Where needed but beware of unmanageable complexity and silly performance assumptions.
