Cipher®: A Proven Framework to Hire the Best People
Most hiring still runs on gut feel, vague job descriptions and unstructured interviews. Craig della Penna's book replaces that gamble with a clear, teachable method.

A process problem, not a people problem
For fifteen years, Craig has helped leaders hire with greater clarity and rigor using the HireBest system. Its key component is the Cipher: a simple framework that defines success before you meet a candidate.
It distills any role into four essentials so everyone evaluates talent against the same standard.
- 1
Charge
Why the role exists.
- 2
Outcome
What changes in year one.
- 3
Deliverables
What the person produces.
- 4
Efforts
How the work gets done.
