PSPINC CEO Kenichi Uchikura's Blog

It takes long to earn a trust/reputation. But it takes very little to completely loose one. When customer stops trusting you, you must justify everything you do until you earn the trust back.

We must

(1) not to think you are always right
(2) not to give up
(3) not to repeat the same mistake
(4) communicate with your customer
(5) evaluate what you did wrong in the first time
