The adoption of an effective maintenance conceptual framework to increase the productivity and overall equipment effectiveness of manufacturing equipment is the subject of this thesis. The company's focus on proactive and preventive maintenance methods is limited, as its documention of maintenance operations and events, skill gaps in technologicalmachinery maintenance, and the lack of a comprehensive and standard maintenance strategy.The average values of quality rate, performance, availability and Overall Equipment Effectiveness of the company obtained are 98%, 61%, 57% and 34% respectively which is low compared to the world-class standards of 99.9%,95%, 90% and 85%.This paper shows how an effective maintenance policy could influence machine productivity and profitability of the company. The productivity index of one printing machine could be improved by an increament of 0.03 and at list 2.07 million Birr per year, i.e. about 13.2% of the machine yearly maintenance budget, could be gaind as a result of the productivity improvement of one printing machine when the company used the proposed maintenance system. A good maintenance conceptual framework is a useful tool for a company to increase its performance and availability, which leads to higher Overall Equipment Effectiveness and productivity. The conclusion was made that implementing a good maintenance conceptual framework can reduce wasted production time, improve productivity, reduce losses, increase the company's competitiveness, reduce machine downtime, reduce maintenance cycle time, reduce machine setup time, increase machine life, and increase company profit.
