Solving complex industrial problems through engineering, systems thinking and technology.

Career-inventory estimates reconstructed from 16 years of project and engagement records; presented as management's own reconstructed count rather than an independently line-audited figure.

1. 1

   Preparation

   Confirm equipment, personnel, tools, software, safety gear, time and mindset are all ready before touching anything.

2. 2

   Damage-control plan

   Assess the risk of any intervention before acting. Never make an irreversible change without the client's explicit, written acceptance of the risk and consequences.

3. 3

   Complete, objective description of the symptoms

   A structured interview, not a guess — how and when it was first observed, whether it's reproducible, recurring or random, correlated with other events, tied to recent changes, or varies by operator, product or time of day.

4. 4

   Document the current state of the equipment

   Back up programs, current configuration and process parameters, and capture the last known-good state if it exists.

5. 5

   Verify the system operates to specification

   Check operating parameters and end-of-life components before assuming a deeper fault.

6. 6

   Analyze and reproduce the symptoms

   Reproduce the failure and document it as completely as possible — record, photograph or film it, and capture every alarm.

7. 7

   Delimit the fault to its root cause

   Three passes: fix any obvious component damage first; run a failure-mode analysis (list candidate causes most- to least-probable, design the simplest conclusive test for each); then a subsystem analysis (isolate and test each component, most- to least-likely). Still unresolved? Assume you made a mistake, not that the fault is unfindable — re-check your own elimination logic, widen the candidate lists, and reconsider system inputs and interactions with other systems.

8. 8

   Document the problem and the solution

   Write it up and build guides so the same fault is prevented or resolved faster next time.

9. 9

   Review the process itself

   A deliberate retrospective — which steps or ideas helped or hindered the investigation, what to improve, and setting concrete commitments to do so.

10. 10

    Close out

    Confirm the fix with the team, celebrate the result, and formalize the documentation.

Source procedure formally ties "sistema" and "proceso" to ISO 9001:2005 §3.2.1/§3.4.1 — the same ISO-literacy reflected in the Expertise section above.
