The progress of the entire project should be reviewed at regular intervals. All project managers should attend meetings for this purpose. All technology is on a continuum. It has no finite beginning. It has no finite ending.
Technology is in a continuous state of evolution.
At times, the speed of technological change is staggering. We view it as revolutionary instead of evolutionary. This has implications for both Research Organisations and Clients. A research and development contract seeks to erect arbitrary boundaries. These boundaries demarcate the start of the project and the finish of the project.
