This report analyses the current operations processes at Donner and provides recommendations supported by calculations to help improve the situation and productivity.
When assessing Donner Company’s current strategic situation, it is noticeable that certain operations of the enterprise are no longer harmonious with its goals. There is an urge to change while concentrating on the firm’s core competency: improving engineering expertise that allows it to produce specialized circuit boards. More attention should be given to gaining new strengths, yielding improved quality and strong on-time delivery. Below are presented recommendations.
Since there is a difference of set-up time and run time between work done manually and with machine, it is critical to define when it is best and efficient to use CNC for both drilling and routing.
