How to motivate staff to encourage their work to avoid the work error?

Moral incentives

Or material incentives

Interesting question as it is multifaceted. Motivation comes from within. If you want to avoid errors you need to tap into the person interests and recognise the importance of recognition. Errors come in many forms, simple errors we manage, catastrophic errors must be eliminated, errors by inexperience persons can be accepted but errors from experienced people are not.

For action to be properly planned you need to understand what the error is and how it has come about. In short you need to be sure you have done your job by providing the staff with the right training and equipment to do their job and ensured they understood the environment in which they are expected to work.

Before there is any action taken on an error be sure you have done your job properly first, then metering out your response with respect and being mindful you are not creating an environment of fear where culture of blame in hibits creativity and innovation. Every risk has a cost you need to be prepared to pay the price. Sometime its making an error.

standing with them at their work station to thank them for their good job, share their successful stories with the team, chat with them to create a bond with the team, an email every now & then on a successful story that they solved regretfully or just a thank you email. be their for them to assist them at all time, specially at if  they are facing a hard customer & take the blame for them so that'll create an encouragement to be strong in the future & loyal to their manager.
