Another form of muda – An Article review

Monday, August 9th, 2010

August 6th, 2010

Number Nine[1]

I have written several articles on the seven types of waste that have been read by a lot of folks. Well now I’d like to expand those seven to nine. As you will see in this article in Six Sigma we are continuously trying to improve even Six Sigma’s tools and techniques. Here a user finds a need to define another type of waste. Why? Because, as Mr. Navetta puts it, categorizing another form of  muda/ waste can help you eliminate it.

So my articles talked of seven and Mr. Navetta now has create number nine. What happen to eight? Well eight is a Toyota developed one called unused employee resources that I included in a category I called Inventories and/or other resources.

Number Nine is: “Material underutilization” Mr. Navetta describes it as leftover material once the material has been used. His example is the “skeletons” from a stamping machine which an excellence example. He says you may not know if it is truly a waste but tag it and find out. He mentions that the spacing could be due to closer would cause stress within the part. But I am with him, ask the question. It maybe that with a re-layout of the die one could get more pieces from the sheet.

But stamping is not the only place. Think about forms where we have multiple copies that are sent out. Many times processes get changed where fewer copies are needed and the number of copies is not changed. It is material that is under utilized and a waste.  We will tend to throw the extra copy away rather than get the form changed.

Can you think of other situations that fit into this category of waste? Leaving a comment below, emailing me, call me, or leaving a comment on my website.

Great article kudos to Mr. Navetta

3rd Step – Subordinate all other Tasks to the Constraint

Thursday, June 24th, 2010

surgeon

In constraint management after you have identified and exploited the constraint, you must subordinate all other tasks to the constraint. If you do not do this all you will have is people wasting time and materials creating parts of a completed product that no one wants. Then you have to spend money keeping track of all the excess inventory until you can use it. It is better to move those resources to helping the constraint task complete its works as quickly as possible. Think of your constraint as the surgeon of the process. All other tasks being performed in the operating room are subordinated to the surgeons work. Materials and tasks are brought in for use right when the surgeon needs them. Here are some helpful hint about subordination.

  1. You can decrease the output of all the rest of the tasks in the constraints process. Tasks before the constraint, will just build up inventory that cost you money. Money tied up in materials and labor to create the inventory that is sitting waiting for processing at the constraint. While it seats you have to keep track of it and store it until you use it. This also happens at tasks after the constraint. Here processes build inventory that sits waiting for the constraints task to be completed before they can complete their task.
  2. Since the capacity of the other tasks is larger than the constraint you can cut back on the utilization of the resources at those task and even move them to help the constraint. Sometimes these resources may not be as efficient as what is at the constraint but every little bit of output at the constraint helps.
  3. Increase the time that the constraint is being run. If the constraint task is only being done Monday through Friday from 8 – 5, then add the weekends or shifts for the constraint, This will increase the overall output of the process.
  4. Make sure that everyone know what the constraint is and what is needed at the constraint to keep it working. Put the information in every tasks written procedures. This way everyone will know the importance of keeping the constraint running and will make it their job to see it is working full time.
  5. Put in place a way to monitor the constraint so everyone know how it is doing at all times. Monitor Constraints throughput and/ or buffer sizes. Information is a great thing when everyone know what is happening and what is important.


Well there you have how to subordinate all the other tasks to the constraint in your processes. Next time I will address how we elevate a constraint. The forth of five steps in constraint management.

Creating Customer Value or should I say Removing Non Value

Monday, April 12th, 2010

I have seen many companies trying so hard to get their employees to work harder creating more value for their customers. Trying constantly to keep a competitive edge over the competition. And yet when they really look around their employees are working already so hard. In fact, I’d say, people are busy 99% of the time trying to do a good job. So how does a company today meet this challenge, it is in the things the people do. The process! It is not the “people” that creates the value, but the activity (process) they do that creates it. You can actually see this but looking at the “things” (paper or product) in the process evolving into customer needs. If you focus on the “things” in the process and NOT the people you will see that those “things sit there not doing a thing 99% of the time. So to increase value to your customers you need to take the time wasted by the things in the process  just sitting doing nothing and remove it.

How do you do that? Simple, buy looking at the entire process. Look at things people are working on. If you see things that no one is working on then you can bet there is no value being added. Those steps/activities should be eliminated thus removing wasted time from the process. This concept is applied using what is called a Value Added Flow Analysis and I am going to quickly give you the “How To” perform one.

Value Added Flow Analysis

  1. Capture all the steps in the entire activity/process from beginning to end.
    1. To do this you follow one of those “things” (paper or product) from the receiving dock to the customers hands.
    2. Record EVERTHING that happens and how long it takes. I mean everything! Including, for example, the “step” of the thing (order) sitting is a briefcase or notebook as it is transported back to the office to be entered into your system. Or the “step” of the thing (your lunch order at a restaurant) sitting on the note pad as it travels to the kitchen. EVERYTHING! This list will be long both in time and steps.
  2. Next you will take this list and look at each of those step and determine if it is value added or not. So how do you  determine if it is value added? Value added steps can be identified by answering three questions about each step. All three questions have to be answered YES! If any are answered no then they are “non value added steps” and need to be put on the list to be elimination or improvement. Here are the three questions:
  1. Does the thing in the process change? If the “thing” is paper was some information recorded on it? If the “thing” is a product was something added to it?
  2. Does the customer care about the change? In other word are they willing to pay for the change that happened to the thing in the process.
  3. Was it done right the first time? Remember that you, as a customer, do not what to pay for mistake or redo’s and you surely do not want to wait for the error to be corrected. This is of no value to you.

Once you have identified all the value added step then you need to eliminate or significantly improve all of the others. In a simple world you would just eliminate all of the non-value added steps. But our world that is not so easy to do, but I do feel you can eliminate about 75% of them.

    Non Value Added Step Eliminating:

    How can I be so sure that you can eliminate 75% of these steps; experience. Over the years I find over and over again that you can eliminate about 75% of the non value added steps. Look at one of your processes. When you first developed this “process” it was done a certain way. If lucky that way was written down as a procedure. But as time changed so have customer needs and to meet those needs you have adjusted your process. Over time with all the “adjustments” you now have a process that has several steps that are not needed any more to meet old needs that are no longer there. Another example maybe that the “process” has been handed down from employee to employee (no documentation) and each has done it slightly different. So in time the process has shifted from a originally good one to one that is different during which time the customer needs have changed as well. In either case steps have been left that create no value for your customer and need to be eliminated.

    Non Value Added Step Improvement:

    OK not everything can be eliminated. Why? Because many time we have more than one customer set of values and we have to prioritize, not eliminate, what we are doing. Be careful you are not micro managing something for you own interest and NOT your customers. A good example of a non value added step that can not be eliminated is Taxes. The “Paying Customer” does not care whether you pay them or not. But to stay in business you have to. Some look at the IRS as another customer (although not a paying one). So in these cases you have to look at ways of completing those steps as quickly and correctly as possible.

    Well there you have it. How to create value without something new, but by eliminating waste. That is of value to the customer in that it reduces cost without reducing quality and they receive it sooner than expected.

    The Seven Types of Waste a Summary

    Wednesday, September 30th, 2009

    You may have seen a couple of posts I have done on the seven types of waste. I have completed seven articles on all seven types of waste you might find in your organization. Below is a listing and a short description for each of the seven types of waste plus a link to the full article. I believe if you read these articles you will have a new way of looking at your business.


    The Seven Types of Waste:


    Correction - Corrections are and time you redo, rewrite, rework, repair, or scrap something. This can be as simple as rewriting a grocery list. Say you have a grocery list but you want to rearrange the items on it in the order you will encounter them in the store. Even though it will speed things for you shopping it had to be redone instead of thinking of making the list ordered in the first place. Redoing the list did not add any value to you; it took longer to write it a second time instead of doing it right the first time.


    Overproduction - Overproduction is when you make too much of something or you perform too much of a service for some one. Have you ever held a meeting and made copies for that meeting? Most people make a few extra, do you? That is overproduction they will end up in the trash. Or have you every as a question about something in a store and the salesman goes on an on answering your question when all you wanted was the simple answer? That salesman was overproducing


    Movement of material or information - This type of waste is when you take any material for information and have to move it from one place to another. You may ship it or carry it your self but that movement does not create any value for the customer in fact it is lost time because it delays your product or service from getting to your customer


    Motion of employees - This type of waste is when you or an operator has get up and walk or travel to get something to do their job.  Just like movement of materials and information, motion of the operator does not create value. In fact the "thing" in the process is not changing at all


    Waiting - This type of waste is when you, other employees, customer, material, or equipment sits idle waiting. Think about all the waiting rooms there are. As a customer do you want to wait? No but we sometime have come to expect the wait. I have been to doctor’s office where the waiting room is empty or full did not matter but in some I was seen on time and other I have waited over an hour.


    Inventory or other resources - This type of waste is not just supplies and materials on shelves but also any recourse your company has that is not being utilized. We normal see inventory as parts and supplies sitting on a shelf like boxes of cereal in the grocery store. But here inventory also include equipment that is standing idle or in storage and employees that have skill that are not being used to their fullest.


    Processes - This type of waste is when you are doing more than required by the customer. This is a hard one to understand because sometimes doing more for free has a WOW factor for your customers. That is why it is important to know what is of value and what is not. You see sometime you do sometime more that you think the customer wants and they do not care. That is when it becomes a waste.

    The Seven Types of Waste (Processes)

    Tuesday, September 29th, 2009

    Bersbach Consulting LLC provides Six Sigma training coaching and support across Arizona, including the Tucson, Phoenix, Sierra Vista, Nogales, Yuma areas. At this time we would like to thank our friends and clients for their support. If you have landed here looking for our Six Sigma training, coaching or support services in Tucson, then please follow this Six Sigma Training link.

    This is the seventh in a series of articles on the Seven Types of Waste[1]. This article addresses Processes.

    Processes

    ProcessingThis type of waste is when you are doing more than required by the customer. This is a hard one to understand because sometimes doing more for free has a WOW factor for your customers. That is why it is important to know what is of value and what is not. You see sometime you do sometime more that you think the customer wants and they do not care. That is when it becomes a waste.

    Also many time we do things that customer thinks are great but then customer values change and the process did not. Those also become waste. Ever hear some one explain what they do as “… because we have always done it that way”. That is a flag that this could be a waste and needs to be changed. Just because we have ALWAYS done it that way does not make it the best or most efficient way to do it. Customer values change and so does the technology that is used to create value.

    Take a letter for instance, once upon a time we hand wrote letters and sent them in the mail. Then there were typewriters; then computer; and now we have Email. So you see the world is constantly changing and as such so do you processes. Change to insure they are always creating the best value for your coustomers.

    Some symptoms of Process Waste that you can look for are:

    Unnecessary work

    Extra equipment

    Longer lead time

    Reduced productivity

    Extra material movement

    Sorting, testing, inspection

    Inappropriate use of resources

    Excess energy consumption

    Processing by-products

    Look around your place of work or at home and see if you can see any of these. They are just the flag that there is a cause for these that needs to be identified and addressed. What are some of the root causes associated with these symptoms? Let me list them as well. I would associate them with the symptom but many times a root cause shows more than one symptom. So as you read this list of root causes look at the symptoms above and see how many of them it could cause.

    Some Root Causes of Process Waste are:

    • Product changes without process changes
    • Just-in-case logic
    • Old Habits (it’s always been done)
    • Lack of communication
    • Redundant approvals
    • Extra copies, excess information
    • Undefined customer requirements
    • “Stop-gap” measures that become
    • part of the process
    • Lack of reuse / recycling

    I invite you to post what you see around you that are Process Waste that could be changed.

    The Seven types of Waste (Inventory)

    This is the sixth in a series of articles on the Seven Types of Waste[1]. This article addresses Inventory.

    inventoryInventory

    This type of waste is not just supplies and materials on shelves but also any recourse your company has that is not being utilized. We normal see inventory as parts and supplies sitting on a shelf like boxes of cereal in the grocery store. But here inventory also include equipment that is standing idle or in storage and employees that have skill that are not being used to their fullest.

    Some times we do not realize how much we spend on skilled employees that are actually doing work that does not maximize their skill set. Take a look at any given skilled employee and think about what they are actually doing during their days work. Now ask your self how much of that required their special skills; I believe you would find that there are a lot of activities they are doing that do not need their skills. Those activates could be off loaded to someone else at a lower pay scale to do. Meanwhile the skilled worker could be working on another active that does require their skills. In this way you decrease costs and increase throughput.

    Equipment is usually a capitol expense and as such if it is not working it is costing you money in floor space and maintenance and maybe even loans. I have an old truck at my house that I very rarely use. But I have kept it to “haul stuff” when I need to (have you heard that). I have to pay insurance and maintenance on it even if it sits. Plus I have to run it once in a while just to keep it in working condition. It takes up space in my driveway as well. I should sell it, freeing up the space and saving all the expenses of insurance and maintenance. If I need to haul things I could rent a trailer or buy one which would cost me less than what I am currently doing with the truck.

    You get the idea!

    Some symptoms of Inventory that you can look for are:

    • Complex tracking systems
    • Extra storage & handling
    • Extra rework / hidden problems
    • Paperwork / documents
    • Stagnated information flow
    • High disposal costs
    • Obsolete material
    • In-process packaging
    • High utility costs

    Look around your place of work or at home and see if you can see any of these. They are just the flag that there is a cause for these that needs to be identified and addressed.

So as you read this list of root causes look at the symptoms above and see how many of them it could cause.

    Some Root Causes of Inventory:

    • Product complexity
    • Incapable processes
    • Unleveled scheduling
    • Poor market forecast
    • Unbalanced workload
    • “Just-in-case”
    • Unreliable supplier shipments
    • Inadequate measurement
    • Misunderstood communications
    • Reward system (wrong metric)

    I invite you to post what you see around you that are Motions of Operators that could be changed.

    The Seven Types of Waste (Waiting)

    This is the fifth in a series of articles on the Seven Types of Waste[i]. This article addresses waiting.

    Waiting

    WaitingThis type of waste is when you, other employees, customer, material, or equipment sits idle waiting. Think about all the waiting rooms there are. As a customer do you want to wait? No but we sometime have come to expect the wait. I have been to doctor’s office where the waiting room is empty or full did not matter but in some I was seen on time and other I have waited over an hour.

    Ever gone to a meeting only to have to wait because some one was late? Or maybe you showed up late. Think of all the dollars in pay being spent while employees sit wait to start.

    How about that order form that you filled out online but did not get filled until the next day. How many times did that sit and wait? Or have you seen key equipment sitting waiting to be repaired? What kinds of cost are there in that delay?


    Waiting is a big one in my book. Why, because many times we, as customer, have come to expect it in some companies or industries and yet we don’t in others. Why is that? It’s because that is the way it always has been. But we as customer pay for it just as your customer pay for the waiting that happens in your organization.

    Some symptoms of Waiting that you can look for are:

    • Under-utilization of resources
    • Reduced productivity
    • Increase in investment
    • Idle equipment
    • Large waiting / storage rooms
    • Equipment running, not producing
    • Unnecessary testing

    Look around your place of work or at home and see if you can see any of these. They are just the flag that there is a cause for these that needs to be identified and addressed. What are some of the root causes associated with these symptoms? Let me list them as well. I would associate them with the symptom but many times a root cause shows more than one symptom. So as you read this list of root causes look at the symptoms above and see how many of them it could cause.

    Some Root Causes of Waiting:

    • Unbalanced work load
    • Late start of meetings
    • Unplanned maintenance
    • Long process set-up times
    • Misuse of automation
    • Quality problems
    • Unleveled scheduling
    • Ineffective layout
    • Specialization
    • Batch processing
    • “Things” not at right    location

    I invite you to post what you see around you that are Motions of Operators that could be changed.

    The Seven Types of Waste (Motion of Operators)

    Tuesday, September 8th, 2009

At this time we would like to thank our friends and clients for their support.

    This is the fourth in a series of articles on the Seven Types of Waste. This article addresses excessive motion of operators/employees.

    First before I get into motion let me explain what waste is in six sigma. Waste is any activity that does not produce value, value in the “eyes” of the customer, not you. The seven types of waste are:

    1. Corrections
    2. Overproduction
    3. Movement of material or information
    4. Motion of operators
    5. Waiting
    6. Inventory or other resources that are not being used
    7. Processing

    motionMotion of Operators

    This type of waste is when you or an operator has get up and walk or travel to get something to do their job.  Just like movement of materials and information, motion of the operator does not create value. In fact the "thing" in the process is not changing at all.  Let’s take the simple act of changing the oil in your car. If you do it yourself then to have to travel (motion) to get the oil and tools to change it and then afterwards you have to put the tools away and dispose of the old oil both motions.

    If you take your car to a service shop to have the oil changed you will notice right away that they have the oil and tools right there in the service bay. Once they are done the tools are place back in their place in the bay and the used oil is held in a large container that will later be taken (motion) to be disposed of. This disposal has been combined with several others thus reducing the motion of the disposal...

    Many times when we have a job to do around the house it is not the job we mind but the setup. Why, because instead of just doing the job we have to go around and gather what we need to get the job done first (motion). Plus usually, if you are like me, we missed a few things and have to go back to the store to get them (Correction and motion happening at the same time).

    Some symptoms of motion of operators that you can look for are:

    • Reduced productivity
    • Large reach / walk distances
    • Longer lead times
    • Excess handling
    • Reduced quality
    • People / machines waiting
    • High energy cost
    • Inappropriate use of resources

    Look around your place of work or at home and see if you can see any of these. They are just the flag that there is a cause for these that needs to be identified and addressed. What are some of the root causes associated with these symptoms? Let me list them as well. I would associate them with the symptom but many times a root cause shows more than one symptom. So as you read this list of root causes look at the symptoms above and see how many of them it could cause.

    Some Root Causes of Motion of Operators:

    • Poor ergonomics / layout
    • Machine / process design
    • Inconsistent work methods
    • Poor workplace organization & housekeeping
    • Extra “busy” movements while waiting

    I invite you to post what you see around you that are Motions of Operators that could be changed.

    The Seven Types of Waste (Movement of Material & Information)

At this time we would like to thank our friends and clients for their support. If you have landed here looking for our Six Sigma training, coaching or support services in Tucson, then please follow this Six Sigma Training link.

    This is the third in a series of articles on the Seven Types of Waste. This article addresses excessive material and information movement.

    First before I get into Material and Information Movement let me explain what waste is in six sigma. Waste is any activity that does not produce value, value in the “eyes” of the customer, not you. The seven types of waste are:

    1. Corrections
    2. Overproduction
    3. Movement of material or information
    4. Motion of operators
    5. Waiting
    6. Inventory or other resources that are not being used
    7. Processing

    Movement of material or information

    This type of waste is when you take any material for information and have to move it from one place to another. You may ship it or carry it your self but that movement does not create any value for the customer in fact it is lost time because it delays your product or service from getting to your customer. Even an Email (information being moved from one person to another) is a delay. You may not have to physically take it to the person but you had to prepare the info for sending, send it, and the other person had to receive it. It may wait in their inbox for a day or more unless you spend more time and call them to expedite it. All that movement is just a waste.

    Some symptoms of movement of material or information that you can look for are:

    • Extra handling
    • Extra handling equipment
    • Extra inventory
    • Large storage areas
    • Over-staffing
    • Reduced quality
    • Extra Paperwork
    • Extra hand-offs
    • Transport of disposal
    • Excessive energy consumption
    • Excessive emissions

    Look around your place of work or at home and see if you can see any of these. They are just the flag that there is a cause for these that needs to be identified and addressed. What are some of the root causes associated with these symptoms? Let me list them as well. I would associate them with the symptom but many times a root cause shows more than one symptom. So as you read this list of root causes look at the symptoms above and see how many of them it could cause.

    Some Root Causes of Movement of material or information:

    • Mis-located materials
    • Unleveled scheduling
    • Unfavorable facility layout
    • Redundant inspections
    • Poor workplace organization     & housekeeping
    • Poorly managed waste streams
    • Unbalanced processes
    • Material stored away from point of use

    This is the second in a series of articles on the Seven Types of Waste. This article addresses Overproduction.

    First before I get into Overproduction let me explain what waste is in six sigma. Waste is any activity that does not produce value, value in the “eyes” of the customer, not you. The seven types of waste are:

    1. Corrections
    2. Overproduction
    3. Movement of material or information
    4. Motion of operators
    5. Waiting
    6. Inventory or other resources that are not being used
    7. Processing

    Overproduction

    Overproduction is when you make too much of something or you perform too much of a service for some one. Have you ever held a meeting and made copies for that meeting? Most people make a few extra, do you? That is overproduction they will end up in the trash. Or have you every as a question about something in a store and the salesman goes on an on answering your question when all you wanted was the simple answer? That salesman was overproducing. In a service industry knowing whether you are overproducing or not is tricky but if you give the shorter version to a customers answer and then ask them if they understand your answer you can find out if they need more information.

    Some symptoms of overproduction that you can look for are:

    • Excessive raw materials
    • Extra inventory
    • Unnecessary work
    • Excessive floor space utilized
    • Unbalanced material flow
    • Backups between departments
    • Complex information management
    • Disposal charges
    • Extra waste handling & treatment
    • High utility costs

    Look around you place of work or at home and see if you can see any of these. They are just the flag that there is a cause for these that needs to be identified and addressed. What are some of the root causes associated with these symptoms? Let me list them as well. I would associate them with the symptom but many times a root cause shows more than one symptom. So as you read this list of root causes look at the symptoms above and see how many of them it could cause.

    Some Root Causes of Overproduction:

    • Just-in-case logic
    • Misuse of automation
    • Staying busy
    • Long process set-up
    • Unleveled scheduling
    • Unbalanced workload
    • Low yield
    • Over engineered equipment/capability
    • Redundant inspections
    • Lack of reuse & recycling

    I invite you to post what you see around you that are Overproduction that could be changed.
