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.

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.
