Personal excellence for me is striving to achieve perfection with self awareness of one's own strengths and weaknesses and also an endeavour to be the best in everything one does by putting in 100% effort.
process excellence is ensuring mistake proofing or a zero error approach in an end to end flow of a particular process.A process is termed as excellent if a mediocre user or a user prone to makinng errors is able to get the same output or outcome without any or with minimum variations everytime this process is used.
operational excellence can be defined as perfection or finesse in achieving goal of the operation or mission by means of achieving perfection in meeting customer's expectation and satisfaction by enhancing individual employees' outputs by encouraging team work,keeping the employee's morale and motivation high and making continous improvement in processes.
Business excellence can be defined as achieving higher level and consistency of performance in the operations of an organisation..it is achieving perfection in achieving the goals of the organisation by increasing overall efficiency of the operation by minimising waste in production of goods and services and increasing loyalty of employees.It is constant evaluation of policies and Standard operating procedures in order to identify areas which have scope of improvement.
To summarise personal excellence if achieved by each employee clubbed with process excellence would enhance operational excellence and in turn result in business excellence.
