2. Improving Your Business Results Six Sigma Qualtec Six Sigma Qualtec Six Sigma Qualtec – All Rights Reserved 2 Lean is a production practice that considers the expenditure of resources for any goal other than the creation of value for the end customer to be wasteful, and thus a target for elimination. Working from the perspective of the customer who consumes the product or services, “value” is defined as any action or process that a customer would be willing to pay for …. Lean, whether in Services or manufacturing … is based on the premise that anywhere work is being done, waste is being generated … and should be minimized or removed … is about doing more (customer value) with less (resources) … is about removing complexity … is about reducing inventory and WIP … is about improving flow, pull instead of push … is about doing things faster … is about reducing costs … Is about increasing capacity is not about eliminating people What is Lean … really?

It is Systems thinking irrespective of deliverable and improvement tools. Certain things must happen –Goals as expressed by Dashboards/Scorecards (OpEx doesn’t set them…just needs them expressed in terms of measureable outputs) –Governance – The decision process to identify, select and prioritize the activities that drive performance. EVSMs and Process Metrics are the foundation tools. –Improvement Activities – The problem solving approaches and tools used to execute projects Driving Performance improvement isn’t a Lean initiative, it’s a business initiative. Solving specific problems with Lean in either mfg or services starts by identifying a S-M-A-R-T project charter and understanding processes with process characterization. Significant improvements in both services and manufacturing can be realized through “Lean thinking”, and recognizing opportunities to improve through Lean “lenses”

8. Improving Your Business Results Six Sigma Qualtec Six Sigma Qualtec Six Sigma Qualtec – All Rights Reserved 8 Unique Aspects of Services There is typically greater involvement of customers in the production process. In many cases, the customer is a supplier to the process. –Sometimes the involvement is so ingrained in the process that you really end up with co-production with the customer. Since services processes are often very people-centric (vs. machine-centric), it is very difficult to get to real standardization. Quality is an experience, not just a measurement against specifications. The inability to standardize the process makes it very difficult to standardize quality. The customer’s definition of quality is a perception, subjective vs. objective

9. Improving Your Business Results Six Sigma Qualtec Six Sigma Qualtec Six Sigma Qualtec – All Rights Reserved 9 Unique Aspects of Services There is much less visibility to what is actually happening. Information is flowing, not product, and that information can be digital, paper, or even verbal. And, HOW it flows often has little or no standardization IT systems play a much bigger role. They enable the process, but can also be a rigid constraint on the process. There may be multiple and often un-integrated systems. Workarounds persist in the form of excel spreadsheets, word docs, etc WIP and inventory are often hidden and ignored, but they are there and can have the same negative impacts as in a manufacturing environment (e.g. wasted resources, longer lead times, more variation

10. Improving Your Business Results Six Sigma Qualtec Six Sigma Qualtec Six Sigma Qualtec – All Rights Reserved 10 Lean’s fundamental focus of eliminating waste aligns well with the concept of preserving value with less work and doing more with less. Lean thinking provides specific “lenses” for looking for different types of waste in your services or backoffice processes …

11. Improving Your Business Results Six Sigma Qualtec Six Sigma Qualtec Six Sigma Qualtec – All Rights Reserved 11 Examples of Waste in Services Transportation (Handling). Movement of paperwork, multiple hand- offs of electronic data, approvals, excessive email attachments and distributing unnecessary cc copies to people who don't really need to know Inventory. Purchasing or making things before they are needed (e.g. office supplies, literature...). Things waiting in an in-box, unread email and all forms of batch processing create inventory Human Motion. Walking to copier, printer, fax... Walking between offices. Central filing. Unnecessary meetings … Waiting. Slow computer speed. System downtime (computer, fax, phone...). Waiting for approvals, waiting for customer information or waiting for clarification or correction of work received from upstream process create much waste in office and business systems.

12. Improving Your Business Results Six Sigma Qualtec Six Sigma Qualtec Six Sigma Qualtec – All Rights Reserved 12 Examples of Waste in Services Overproduction. Printing paperwork or processing an order before it is needed. (things can change) Any processing that is done on a routine schedule - regardless of current demand Over-processing. Relying on inspections, rather than designing the process to eliminate errors. Re-entering data into multiple information systems, making extra copies, generating unused reports, and unnecessarily cumbersome processes are overprocessing. Demand-side waste can create over-processing Defects. Data entry errors or invoice errors. Engineering change orders, design flaws, employee turnover and miscommunication are all ‘defects’ in office processes

It is all VERY visible. Various forms of information, documents, etc in paper, digital, or even verbal form. Flows in many cases are not visible.

15. Improving Your Business Results Six Sigma Qualtec Six Sigma Qualtec Six Sigma Qualtec – All Rights Reserved 15 Resulting Differences in Application of Tools ‘Most organizations, for example, used just a few tools, such as value stream mapping. This implies that many of the tools and techniques used in a manufacturing context are currently not immediately and obviously applicable to service environments. Instead, some of the tools need to be adapted to cope with the need for greater process flexibility…may be because the service sector has yet to understand the value, relevance or purpose of the tools being applied from within the toolkit.’ (Radnor 2006)

19. Improving Your Business Results Six Sigma Qualtec Six Sigma Qualtec Six Sigma Qualtec – All Rights Reserved 19 Failure Demand Waste - Service Blueprinting Service Blueprinting puts the customer at the center of the process map Putting customer at the center gives you a better starting point to determine predictable demand flow It also gives you a picture of “failure demand” which is a core service organization’s waste and not one of the items listed originally in TPS as MUDA. But this opens a whole way of thinking which most organizations are ill prepared to support organizationally or with data.

20. Improving Your Business Results Six Sigma Qualtec Six Sigma Qualtec Six Sigma Qualtec – All Rights Reserved 20 Summary Manufacturing and Service Environments are obviously not the same and must be treated differently Fundamentals of OpEx and Lean still apply Tools are adapted (some might call it simplified) and the emphasis is changed The key to success is in the Project Selection which is challenging often relying on experience in lieu of well documented processes which would kill any momentum to first obtain The impact is large because of the amount of waste yet its not dealing with the greatest potential inherent in the overall system
