It's not a rhetorical question. Construction costs, interest rates, grant funding, rental values and programme timings have all moved - sometimes sharply, over the past two years. The Regulator of Social Housing has been explicit that financial resilience and effective risk management are central to how providers are now judged. A viability appraisal is only as useful as the assumptions behind it, and a small change in one assumption can ripple through the viability of an entire scheme.
From static assumptions to live decision-making
That has practical implications for how appraisals need to work. They can no longer be something built at the start of a project and revisited only at key milestones. They need to function as living models that evolve alongside the scheme itself.
When appraisal, project and financial information are connected rather than siloed, teams can get answers faster: What happens if build costs rise again? What if a scheme slips six months? What if grant funding changes? What does that mean for the wider programme if one project slips into the next financial year?
This kind of scenario testing matters more than it used to, because the question boards and senior teams need answering isn't just whether a scheme is viable today, it's how resilient that viability is if the ground shifts beneath it. Tools such as M3Pamwin Plus support this by allowing organisations to model different scenarios, update assumptions and see the resulting impact on appraisal and cashflow, including for complex, phased schemes, with project information visible across the wider programme.
The shift, in effect, is from "Is this project still viable?" to "How robust is this project, and what happens if things change?" It’s a more honest question, and one that regulators and funders are increasingly expecting housing providers to be able to answer.
Governance depends on the numbers being trustworthy
Connected information also strengthens the governance sitting behind appraisals. When assumptions are clearly recorded, models can be reviewed consistently and changes tracked over a project's lifecycle, reducing reliance on individual spreadsheets. It also reduces the risk of key information that might sit with one person or one team, becoming invisible if they leave or are simply unavailable.
In addition, it allows development, finance and senior management teams to work from the same figures when reviewing performance and making investment decisions. That matters because confidence in a number isn't just about the calculation being right, it's about being able to explain, challenge and defend it when asked.
From appraisal to programme
The benefits don’t stop at individual project. When appraisal data sits alongside programme data, providers can start to see the relationship between individual project performance and the wider pipeline. For example: which projects are most exposed to changing assumptions, where intervention would make the biggest difference, and whether investment decisions still align with an organisation’s financial objectives.
In an uncertain development environment, connected data doesn't just make appraisals more dynamic. It gives decision-makers a clearer basis for the judgement calls that regulators now expect.
In the final part of this series, we move from decision-making into delivery: how teams keep control of programme progress, cashflow and change once a scheme is actually underway.
