Why Just In Time Inventory Is Right For You

In a world of torque wrenches and bolts the relationship between aircraft maintenance planning and suppliers is becoming more important by the day. Just In Time Inventory For Aircraft Maintenance Planning

In the not so distant past we were managing a client's heavy check. In the middle of the project we were requested to supply the expendables for the entire project. This was in addition to the rotables we were already managing. Now, as you know, nothing ever goes entirely as planned. We scrambled, stressed and got the job done but situations like this make the planning process paramount to successful aircraft maintenance check projects.

Last minute procurement and poor forecasting can be costly. It costs more money and time, both being scarce.

The solution to this madness is the Just In Time (JIT) inventory concept.

JIT is a production strategy where you can improve your organization's bottom line by minimizing in-process inventory and carrying costs.

Have you ever thought about the total cost of waste on your shelves because you bought too much material or they're now obsolete or expired?

Just In Time inventory for your expendable needs

Raw materials, such as expendables and consumables, are an integral part of your maintenance processes but they can be costly sitting on the shelf at undesired times. Or even worse, you don't have enough spares available for your maintenance needs. You then have to procure your expendable needs on an AOG basis, increasing cost, stress and the time you spend on the project. Both scenarios are bad.

Just In Time inventory is a strategy you may want to consider to have the raw material available only when you need it. The material arrives and is immediately consumed by your maintenance needs. Reducing inventory and processing time.

Benefits of a JIT system

A buffer of inventory can be extremely comforting but it's also very costly. Once you start holding excess expendables in inventory you begin locking away cash needlessly. These items can be lost, damaged or become obsolete over years of unnecessary storage. They occupy valuable space that you could further use towards your operation.

One of the greatest benefits of the JIT system is it allows you to carry low inventory. You receive the material as you need it, just in time. There's no need to write off large inventories. You consume it when you need it, skipping the inventory process.

Another benefit of a JIT system is the reduction of waste. If material goes beyond its expiration date, corrodes or becomes unusable the cost of material rises. By eliminating waste you control cost.

A third key benefit to the JIT process is high quality production. Since you'll only be dealing with suppliers whom you trust, they will understand your needs and make sure quality is of utmost importance. This will eliminate rejected parts through your quality control process and quicker consumption rates for your aircraft maintenance planning.

JIT, stakeholder relationships and aircraft maintenance planning

The Just In Time inventory strategy is useless without a strong relationship with your supply chain. Providing your suppliers with material consumption forecasts and what you expect from them is crucial to a successful JIT relationship. By tapping into your suppliers to fulfill needs that could cost you millions is an ideal scenario.

This entire process is an evolution of change. As you begin to work with suppliers through you JIT strategy improvements will be made and cooperation will become tighter.

Aircraft maintenance planning can be costly but unnecessary spending is avoidable. With excess inventory comes excess cost, so why not receive goods just in time for consumption? By tapping into strong relationships with your supplier you'll know what parts are needed, when they're needed and receive them as needed.

If you have out of control raw material costs, a JIT strategy may be exactly what's needed for your aircraft maintenance planning needs.

Why Six Sigma Is Essential To Reducing Your Aircraft Maintenance Cost

You and I can agree that accurately forecasting aircraft maintenance cost is a job for a mathematician. From statistical analysis and exponential smoothing to extrapolation and the econometric forecasting, it's a world of its own. Did reading those terms bore you? I nearly fell asleep just typing them.

While focusing on your aircraft maintenance cost, there is one proven method that can help regain control of cost variation and waste.

Six Sigma Is Essential To Reducing Your Aircraft Maintenance Cost

The method which I'm talking about is Lean Six Sigma.

This methodology is known all over the world so I can be safe to say that I don't have to define it here. Instead let's discuss it's implication and how it can help you control your maintenance activities.

Key Principles of Lean Six Sigma And Your Aircraft Maintenance Cost

Lean Six Sigma is a proven method for improving your maintenance efficiency and effectiveness. Here are 6 principles to follow when implementing Lean Six Sigma:

-Identify your value stream and how the work gets done. -Manage, improve and smooth the process flow. -Remove waste. Non-Value-Added steps increase cost. -Reduce variation by managing by fact. -Involve the right people in the process who are fully equipped. -Engage in improvement activities in an organized way.

These 6 principles are vital to a successful Lean Six Sigma team. The key is to reduce waste and focus on value added activities. If a technician is running around to multiple projects, there is a possibility they may miss an important aspect of the inspection. This was mentioned in our last article.

In order to accomplish this, you must also implement a framework that can help with this process.

For improving activities in your maintenance processes you'll need to employ the useful framework of DMAIC.

Use DMAIC In Lean Six Sigma

To undergo improvements in regards to your aircraft maintenance processes utilizing Lean Six Sigma, you will need to use the framework of DMAIC.

Define: All projects start with a problem. This problem needs to be defined and everyone involved knows their role. Think about why you're doing this project and what you're trying to achieve.

Measure: The Define stage is what you "think" the problem is. Through the measure stage you'll need to be clear by coming up with how the work gets done and how well once finished.

Analyze: Now that you have an understanding of what is happening, it's imperative to find out why. Never jump to any conclusions. Manage by fact and narrow down to the best possible causes. Once the possible causes are identified you can pinpoint the root cause.

Improve: Now that you've identified the process and the problem, here is where you identify a solution to the root cause. Come up with various ideas and select the best one. Once the best one is selected, test it out.

Control: You need to control the gain you're trying to achieve. Come up with a control plan so the process is carried out consistently.

Utilizing DMAIC is imperative to the success of your Lean Six Sigma and cost control endeavors. Here is an easy way to identify your wastes.

Meet Tim Woods

In order to be successful at reducing your waste, you must first identify it. Use the acronym Tim Woods to achieve this.

T: Transport – Moving people, products & information I : Inventory – Storing parts, pieces, documentation ahead of requirements M : Motion – Bending, turning, reaching, lifting

W: Waiting – For parts, information, instructions, equipment O: Over production – Making more than is IMMEDIATELY required O: Over processing – Tighter tolerances or higher grade materials than are necessary D: Defects – Rework, scrap, incorrect documentation S: Skills – Under utilizing capabilities, delegating tasks with inadequate training

By utilizing Lean Six Sigma within your aircraft maintenance process you'll ensure that the varying cost can be reduced in one aspect or another. Don't let wasteful process deplete your bottom line. I encourage you to implement the Lean Six Sigma way and to reduce aircraft maintenance costs throughout your organization.

It may seem difficult at first but it'll save you from days which you result to hair pulling, screaming and banging your fist on the floor. Your goal is efficiency and less stress.
