Operate / p re t / v.

Manage, work, control; put or keep in functional order.

Oxford Dictionary To complete the CDIO process, engineers need to ensure that whatever they have Conceived, Designed and Implemented is safely, effectively and sustainably Operated. They also need to ensure when the product or system they have created reaches the end of its life, it can be retired with the least impact on the environment.

7.1 Sustainable and Safe Operations The Operation stage of the CDIO process can be the longest in the entire CDIO process. A bridge, for example, can take few years to construct but can remain in Operation for centuries. Likewise an airplane or a car can remain in service for decades. During the Operation stage, engineers need to ensure safety and sustainability, both economically and environmentally.

7.2 Operations Management Depending on the complexity of the system, Operation management includes installation, commissioning, testing, maintenance and daily operation. If the system is a petrochemical plant, commissioning and testing could take up to weeks or even months to ensure that all the parts of the plant are working well and that all the safety equipment is functional in a variety of operational scenarios.

7.3 Training and Operations Whether you buy a new car, mobile phone, television set, software package or furniture from IKEA, they all come with a user manual or user guide that outlines the best way of using them and how to take care of them. In the case of IKEA furniture, the user guide shows how the furniture is assembled. For more complex systems, manufacturers need to develop maintenance manuals and training materials for the service and maintenance staff. This includes a certification programme for the maintenance staff. Examples of highly complex systems would include airplanes that are sold to airlines around the world. Manufacturers of airplanes run training and certification programmes so that the technical staff operating and maintaining the planes are able to perform their intended duties.

7.4 The Birth of the Checklist The Boeing Model 299 (later renamed B17 Flying Fortress) was one of the most impressive long-range bombers of its time. The plane had a wingspan of 32 m and a length of 23 m. Equipped with 4 engines; the plane was fast, had a great range and was able to carry a tremendous load.

October 30, 1935 was the date chosen for the plane to be tested at the Wright Air Field at Dayton Ohio by Boeing’s chief test pilot, Leslie Tower, and Major Ployer Peter Hill, the air corps’ chief of flight-testing. The plane taxied down the runway and after reaching an elevation of around 100 m, the plane stalled and crashed into the ground killing both pilots. The air crash investigation concluded that the cause of the crash was ‘human error.’ The B17’s might came at a price, it was very complex to operate.
