Replacing old machinery

Machinery is one of the most important factors in a producing good quality products and producing them at low cost. Most machinery and plant can be depreciated over 10 years and some large industrial plant and equipment over more. The actual rate of depreciation should match the use of the machinery during its life minus any scrap value. All plant and equipment should be maintained properly and effective monitoring put in place to detect any premature wear and maintenance requirements. This is one aspect in attaining a reliable plant and being able to produce effectively in a lean manufacture system.

Unreliable Plants in Lean Manufacturing

The unreliability of a plant can be detrimental to the process of continuous improvement, specially in a continuous or continuous batch process due to the limited material/ WIP flow alternatives within the process. Many plants may be old and have new technologies fitted to old backbones which can also compound the problem. It is a great advantage in having at least plant up times of around 95% because this will allow engineers to implement quicker change over times and improved cycle times.

The Lean Journey understanding the process

Understanding Lean manufacturing goes beyond having a knowledge about the different techniques available to improve efficiencies in a process or manufacturing operation. It involves a commitment by both management, operating and support staff in learning and understanding the process in question and being able to utilize engineering resources and knowledge in achieving a reliable plant or system in order to facilitate lean initiatives. This first step of understanding what the organization is dealing with is important because one can not fix the problem if you do not know where or how the problem is being caused. The second step, and a very crucial one in this journey is engineering a system or plant to be as reliable as possible. Until this is achieved any jump towards the use of any lean technique is destined to fail because of the unreliability of the system you are trying to improve.

Lean pitfalls

Going lean? or trying to cut waste and improve operational efficiencies in any production process or service process is a pathway and journey and not a quick fix.
Many managers get excited and use all the buzzwords in meetings and setting their strategy for a lean business. The truth is not many managers really understand the Lean manufacturing concept and few allocate the required resources and steps into creating a sustainable lean culture. One of the very first steps in this pathway is to achieve consistent plant up-time through an appropriate maintenance review program which should aim at making the plant and equipment reliable and minimizing downtime. This is a very important step in the process because if this can not be achieved further efforts and lean applications will be worthless.
