Q.5
The Orange bus company manufacture buses for different purposes.
The Orange bus objective is to provide expert, bespoke minibus conversions for individual customers, companies and charities. The corporate ethos of 'driving quality' focuses the company to continuously look at improving the quality and effectiveness of its products and services. This is demonstrated through high staff morale, increased sales and most importantly satisfied customers. Although The Orange bus was already successfully measuring the quality of its builds and processes informally, the company wanted to put in place a more formal structure to improve operational efficiency and drive market share. The Orange bus decided that a quality certificate would provide the ideal framework to achieve this.
Successful certification may enable The Orange bus to gain national recognition as a quality company which consistently builds a high quality product. The majority of motor manufacturers insist on certification to this standard and The Orange bus has, subsequently achieved national accreditation and approval from these manufacturers due to its outstanding quality.
Auditing is performed monthly and continues to highlight opportunities for process improvements. Non-conformities and corrective actions are religiously logged, enabling The Orange bus to learn from mistakes and put in place initiatives to prevent recurrences of problems. Now that the company monitors each stage of the vehicle build, preventative action means that warranty costs have substantially reduced. The management system also helps the monitoring of customer feedback. As a result of this feedback, the company now offer a 36-month warranty which demonstrates firstly that they do listen to our customers, and, secondly

that they have confidence in the build quality of the product. The only other obstacle they faced was helping staff understand why they were implementing certification.
