Common sense is knowledge based on “native good judgment” and personal experience. It is that combination of “book” smart, “street” smart, and “work” smart that a person can apply to scoping computer validation projects.


  • Helping start-up and small companies new to GXP regulations for computer systems and data integrity compliance.
  • Performing mock audits and third party audits of computerized systems and services.
  • Training and project coaching in computer validation and formal testing practices for passing audits and inspections
