A useful SWOT fits on one page you will stand behind
Strengths, weaknesses, opportunities, threats. The exercise fails when every cell is a slogan. It works when a weakness implies an action this week.
Reading the GIAN diagnostic
Strengths must be checkable (team, field access, prototype). Weaknesses must be honest (no legal entity, no pilot, one partner dependency). Opportunities are external (open call, reform, network). Threats too (FX, climate, competing public programmes).
Feasibility asks whether you can deliver. Impact asks whether it matters to anyone but you. Impact 90 with feasibility 20 is a flag, not a win.
Do not paste the SWOT into the letter as-is
The funder wants a narrative, not a matrix. Translate: this weakness becomes a mitigated risk in the budget; this opportunity becomes why you apply to THIS call and not another.
