Technology Readiness Levels (TRLs) have become the industry standard for measuring technology maturity. They answer an important question:
Is the technology mature enough?
But that's only part of the story.
Technology readiness alone doesn't answer several equally important engineering questions:
- Can the design be manufactured consistently? (We'll discuss Manufacturing Readiness Levels (MRLs) in a future article.)
- Has the design been challenged from every critical engineering perspective?
- Have the highest engineering risks been identified and mitigated?
- Is the product robust enough to perform reliably in real-world operating conditions?
These questions often determine whether a program succeeds or struggles.
Unfortunately, engineering assurance is frequently treated as a separate activity that follows technology development. By the time detailed engineering risk assessments begin, many of the most influential design decisions have already been made. The result can be redesigns, manufacturing challenges, schedule delays, and unnecessary program cost.
At Fortitron, we believe engineering assurance should be integrated throughout the product development lifecycle, not added after technology has matured.
That's why we developed FERF™ (Fortitron Engineering Readiness Framework).
FERF™ integrates:
- Technology Readiness (TRLs)
- Engineering Assurance
- Manufacturing Readiness (MRLs)
into a single, continuous framework that helps engineering organizations strengthen engineering readiness from concept through production.
The benefits include:
- Earlier identification of engineering risks
- Better-informed engineering decisions
- Improved product robustness
- Reduced downstream redesign
- Increased confidence at key program milestones
Technology readiness is essential, but it represents only one dimension of engineering readiness.
A technology may be mature, yet the product can still face significant design, manufacturing, or integration challenges.
TRLs help determine whether the technology is ready. FERF™ helps organizations achieve Engineering Readiness by integrating Technology Readiness, Engineering Assurance, and Manufacturing Readiness into a single framework.
Because mission success depends on more than technology alone.
