The Cost of Complexity

The engineering cost questions buyers type into search and into assistants, answered with a number and the inputs behind it.

Engineering cost is real, but it arrives as payroll and lost weeks, never as a line item. These pages take one question each and put a figure on it: what it costs, why it happens, and which inputs produce the number.

Article 1
Why your engineering team gets slower as it grows
Growth slows delivery for a measurable reason: coordination between coupled parts. Here is what that costs and how to put a number on it.

Article 2
Why small features take months on a legacy codebase
A 40-hour feature takes 464 hours when twelve modules move with it. The calculator returns 11.60x and $69,600 for that feature.

Article 3
What coordination overhead costs a software company
Twenty coordination hours on a 40-hour feature add $3,000 on the coordination line. The annual figure for these inputs is $489,600.

Article 4
How to prove to the board that engineering is underfunded
These inputs put $933,120 a year on the engineering payroll above the work itself.

Article 5
How to calculate technical debt in dollars
A 20-hour feature costs $3,200 alone and $18,560 when eight modules move. The annual figure is $614,400.

Article 6
What module coupling actually costs you
Seven modules moving together, with coordination hours at zero, returns 4.50x, $27,000 per feature, and $1,008,000 a year.

Article 7
Measuring engineering productivity in a language finance accepts
Cost per feature is the productivity number finance can read. These inputs return 3.25x, $19,500 per feature, and $648,000 a year.

Article 8
Rewrite the monolith or keep patching it
The current inputs cost $1,458,000 a year above the work. A second run with a smaller change surface costs $172,800 a year. The gap is $1,285,200.
