I am working for a contracting company that has given me 12 months to
teach 900 employees about Lean Six Sigma methodologies.
I had to strategically align the game plan to maximize the
probability of being 100% successful in my endeavor, since the employment
contract is at-risk for rebid.
The contract involves 900 employees; my strategy is as follows:
- 600 employees who identify as mechanics at 3 different levels
- mech 1
- mech 2
- mech 3 – 3 being the highest level of experience and the most knowledgeable
- 200 employees are leads and supervisors
- 100 employees are managers or exempt employees
***** NOTE – the intersection will be between mech 3 and
leads/ supervisors. Some mech 3’s are leads and supervisors, but not all leads
and supervisors are mech 3’s – they could be mech 1 and mech 2’s.
UNION example of all sets of data:
“Therefore the event set \(\{600;200;100\}\) best describes
the event set of \(A \cup B\) (Siyavula Technology-Powered Learning,
2020).”
600+200+100 = 900
INTERSECTION example:
***** NOTE – the intersection will be between mech 3 and
leads/ supervisors. Some mech 3’s are leads and supervisors, but not all leads
and supervisors are mech 3’s – they could be mech 1 and mech 2’s.
The overlapping shadowed intersection would be: 75 of the
200 employees that are leads/supervisors are mech 3’s. But 225 of the 600
employees are mech 3’s.
“Therefore the event set \(\{75;225\}\) best describes the
event set of \(A \cap B\) (Siyavula Technology-Powered Learning,
2020).”
I found that if I start with the group marked with 200
employees (the leads and supervisors) as opposed to the lowest ranking group of
mechanics who have skillsets at levels 1 and 2 (marked 600 employees), there will be less frustration with regard to
productivity and output, as the decision makers (identified as level 3 and
above), already have an understanding of the fundamentals of change, that is,
Lean Six Sigma methodologies.
Once all of the 200 employees (leads and supervisors),
some of which intersect as mechanics level 3, (75 employees of the group marked
600 employees) are instructed in Lean Maintenance, I can proceed teaching the
group marked 600 employees minus the overlapping 75 employees.
Once these two groups at the production level understand, a refresher course can be given to the managers and exempt employees, ensuring all stakeholders are ready to move forward.
