The Biggest Obstacles to Making Manufacturing Leaner

pragmatic_lean_manufacturingBy reducing waste from operations, implementing Lean manufacturing steps into your business can improve your profitability. Unfortunately, there are issues that present obstacles that must be addressed to achieve this goal.

Time

Tightening any manufacturing process takes time; it is not going to happen overnight. You must make a commitment to leaning your process and you must get everyone on board, working together. The actual amount of time required greatly depends on the number of problem areas a business is facing. The length of time can be reduced with the correct resources, the right systems, designated targets, adequate training and cooperation across all departments.

Resources

Without the right materials or resources, a manufacturer cannot make a product, and Lean manufacturing cannot be achieved. Resources include Six Sigma or Kaizen training, software and IT systems, and a budget to identify and embrace process improvement.

With regards to the software systems, there are many to choose from, each playing a different role. Enterprise Resource Planning (ERP) is management software ideally suited for keeping a record of production as it relates to financial tracking, with individual applications that can be integrated to meet an industry’s needs. Manufacturing facilities can benefit greatly from Manufacturing Resource Planning (MRP) and Supply Chain Management (SCM) systems. The variety of solutions is vast and ERP is no longer just for larger enterprises.

Manufacturing Execution Systems (MES) are designed to collect information from the factory to gain insights into operational performance and quality management. This program can also be integrated into an ERP solution.

Correct targets

Too often, time is lost by focusing on the wrong targets. Companies must be able to look at the entire manufacturing process – from initial order to product delivery – to identify each individual area that is impeding progress. If communication between departments presents an issue, the problem must be corrected. If communication is not an obstacle, the area can be marked as a function to watch.

Many manufacturers will find key areas in inventory, engineering and quality. Once a section of production has been identified, the cause of the failure needs to be analyzed. If duplicate or wrong materials are being purchased, the inventory control system must be updated. These issues require an in-depth evaluation. An inventory issue could be coming from outdated bills of materials or from old engineering designs being used for parts orders.

Rework or production that does not pass quality control is an expensive (and avoidable) cost of manufacturing. The company must determine where the quality is failing, which involves looking at each step of their production process. The problem may not be in the materials used or the skill of the production workers, the problem could be coming from machinery that is out of calibration.

Resistance

A lack of knowledge of what Lean manufacturing means and how the objective is achieved is a large barrier to progress. Lean manufacturing is the elimination of waste in all production areas including production, material flows, quality, delivery and costs. From Just-in-Time systems to reduce inventory to the efficient use of energy, all aspects of production can be improved. In fact, so too can the management process as well.

Managers often present an obstacle in improving the production flow. This may be unconscious or conscious resistance. Many individuals in middle management positions do not want to release the control over operations and may even fear losing their positions.

Production workers can present several obstacles. A large portion of Lean manufacturing is more production in less time at the same or better quality. Employees can be resistant to change and feel that lean manufacturing will require them to work harder. This issue must be addressed by showing workers that the benefit is in streamlined production that is designed to make the work easier.

Without adequate training, employees cannot be expected to manufacture more products while retaining the desired quality level. An investment in training goes a long way toward increasing production and reducing the workload to decrease the resistance.

Follow through

Once your company begins to see the results of a Lean manufacturing program, you must continuously monitor the effectiveness. Backsliding into old habits will occur if no one is paying attention. Lean manufacturing is not a one-and-done function. Kaizen is directed toward waste elimination and continuous improvement — with the key being that must be continuous.
