i Why Continuing Excellence Process Past successes primarily result of staff's possession and superior execution of "hard skills" technical competence root cause determination
~
project management j
i Mature organizations must build upon technical attributes of the j
organization, but add significant investment in " Soft Skills" communication j
workload prioritization and management goal setting l
= Entergy
f Continuing Excellence Process i
New process that creates focused management attention on specific issues The focus is on improvements to plant performance Develop consensus via a process that merges both technical and management issues Action plans are developed that address top site issues entire management team validates the plan Improves our performance in resolving issues through irhproved j
communications r

Continuing Excellence Process Expectations Improvement that is sustained, not cyclical An engaged workforce l
Validation of site focus issues More efficient use of resources A culture that accepts and values continual improvement Improved Execution of " Soft Skills" e
