1) A cause may be necessary but not sufficient for a problem to occur.
Example: An problem has occurred and RCA states that it is knowledge gap. In this case, Knowledge gap is necessary condition for an error to occur but not sufficient. As there are other ways which circumvent knowledge gap by reaching out to supervisor, knowledge library, floor support.
Approach:
1) Identifying the competencies required to perform the job correctly.
2) Grading the person on the competencies identified and bench-marking it against the requisite level.
3) Identify the gap and train the person on the identified gap.
4) Assign a senior or mentor to review his work / address his query.
5) Doing regular intervention by doing quiz, assignment and test to test his competence level.
2.) A cause may be sufficient but not necessary for a problem to occur.
Example: An problem has occurred and RCA states that it is process non conformance. In this case, process conformance is sufficient condition for an problem to occur but not necessary. Since problem can occur because of other causes (knowledge gap, attitude issue, will issue etc)
Approach
1) Identify the measurement areas for process compliance
2) Identify whether it is a skill or will issue
3) if this is skill issue, conduct training, assign mentor, conduct periodic reviews, track performance levels.
4) if this is a will issue, taken action based on level and severity of the non conformance.
5) analyse and design mistake proofing methods to avoid occurrence of the problem and make the entire system process dependent than people dependent and reduce manual intervention.
3) A cause may be neither sufficient nor necessary for a problem to occur.
Example: Recent Mumbai deluge is a perfect example for neither necessary not sufficient condition for problem to occur in any multi-national organization as far as deliveries are concerned.
Approach:
1) Business continuity plan with satellite delivery center and shift as far as operations there
2) Provide work from home for as many people as possible
3) Work with the Client and set appropriate expectations on the delivery front and provide periodic updates.
