Answer 1

Hello

We are most delighted to answer, but I would request you to please ask atmost 1 question or 4 subparts per post. It will be highly appreciated.

(a)

Particulars	Weights	Scores	Weights*Scores
Goal 1	20%	2.0	0.4
Goal 2	20%	2.0	0.4
Goal 3	10%	4.0	0.4
Job Effectiveness	25%	3.0	0.75
Competency 1	4%	2.0	0.08
Competency 2	3%	3.0	0.09
Competency 3	3%	2.0	0.06
Competency 4	5%	3.0	0.15
Core Values	10%	4.0	0.4
Total			2.73

Hence, the weighted average score of the employee is 2.73.

As, the score of the employee is more than 2.5, the employee don't need Performance Enhance Plan.

I hope this solves your doubt.
