The problem with current tools

KISSsoft costs €12,000/year.
Excel has no normative backbone.
There was no middle ground.

Individual mechanical engineers and consultants are priced out of enterprise software — and forced to rely on spreadsheets with no normative context. One wrong $K_A$ propagates silently through every result.

Cost barrier

KISSsoft, MASTA, and Romax are priced for OEM procurement budgets — €12,000 to €40,000 per seat per year. An independent engineer or small consultancy cannot justify that cost.

€12k+/year → out of reach

No normative rigor

Spreadsheets carry no normative context object. A single incorrect $K_A$ or $Z_E$ propagates silently through every downstream result — with no audit trail and no standard to reference.

Silent errors → no audit trail

Iteration speed

Manual ISO 6336 iteration — adjusting x₁, x₂, β, $K_A$ across a full factor chain — takes hours per design cycle. QEVORK closes the loop in seconds, with full coefficient visibility.
