Your company MTech plc (Medical Technologies plc), based in the South West of the UK (10 miles South of Bristol), manufactures, markets, and sells sophisticated cancer screening instruments (CSI). MTech has a world-wide market for the CSI and manufactures between 500 and 600 sets per year. It also has a thriving business in calibration and repair of CSIs. A major sub- assembly of the CSI is a scanner unit (weighing 25kg with dimensions 1m x 1.5m x 0.75m and costs £15,000) that contains radio-active components and is purchased from a company in Germany (ScannerTech) which is located in a small town 5 kilometres north of Leipzig. The repair and calibration of the CSI always involves the fitting of a new scanner with MTech plc providing a guaranteed turnaround time of 10 days.
