Why Manufacturing Teams Must Define the "Why" Before the FMEA

In engineering and manufacturing circles, Failure Mode and Effects Analysis (FMEA) is often viewed as a “box-ticking” exercise—a mandatory, tedious document required by auditors or customers. However, when treated as a mere administrative hurdle, FMEA loses its power.

To unlock the true value of an FMEA, a team must first define the strategic intent: why they are developing the FMEA. Without a clear objective, an FMEA becomes a shallow list of obvious problems rather than a rigorous tool that drives innovation, quality and safety.

An FMEA is more than a document; it is a problem-solving strategy. For manufacturing teams, the goal isn’t to have a completed spreadsheet to show an auditor or to send to a customer – it’s to have a more stable, safer, error-free and profitable operation. By defining the “Why” at the start, you transform the FMEA from a task into a competitive advantage. Teams will focus on improvement rather than the documentation process.

One approach is to ask, “What is the primary risk we are trying to mitigate today?” The answer usually falls into one of these categories:

When a manufacturing team agrees on the “Why”, the scoring process (Severity, Occurrence, and Detectability) becomes objective rather than generic and the reason of the analysis should dictate the depth and direction of the discussion. For example,

How to Start a “Why-focused” FMEA

To help your team develop an effective FMEA, there are several considerations that are essential:

Define the Scope and the “Why”: Never start an FMEA without clearly stating the primary reason for it (e.g., safety, cost reduction, or new technology launch). Establishing boundaries ensures the team focuses only on relevant subsystems or process steps, preventing “scope creep”. Make sure it is signed off by the Plant Manager or Quality Manager.

Select a Cross-Functional Team: FMEA’s should not be an individual assignment. Select team members who are knowledgeable to the subject being assessed and based on the specific “Why”.

Establish Ground Rules & Assumptions: Document the underlying assumptions before starting. For example, when doing a process FMEA we usually assume the design is sound. A Machine FMEA usually assumes the design is sound and maintenance programmes are also sound. This aligns the team’s mindset toward the specific objective.

Assess if you need to adjust evaluation scores: If your “Why” is Safety, adjust your 1–10 scales to more heavily penalise physical hazards. If your “Why” is uptime, penalise minutes of downtime.

Gather Targeted Information: Collect only the documentation relevant to the stated goal, such as process flow diagrams for manufacturing efficiency or historical failure data for quality improvement.

Be focused on actions to be implemented: Address failure modes that are linked with your original “Why.” While the other failure modes are important, you don’t want to waste the resource you have on low-impact issues that do not serve the original strategic intent. They should be recorded and managed by a different team.

How CforC Can Support Your Organisation

At the Centre for Competitiveness, we help build the internal capability required to implement FMEA within your organisation.

We facilitate sessions to review key concepts and help teams focus on how to link an FMEA activity to a strategic objective, how it relates to specific processes or operations, so that the FMEA can be used to engage people in a value-adding exercise that delivers results.

Our goal is simple:
Equip your teams with the practical skills and confidence to improve Safety, Quality, Productivity and Delivery every time.
