  1. Overview Tool Use • Welcome to the DMAIC Template!!! • You can get more helpful hints & ideas if you look at the “Notes” sections below several of the pages (select “View”, then select “Notes Page” to see both the slide and the notes below). • There are several imbedded tools that may help you. Use the tools &/or pages you need and delete the rest (e.g. you’ll see both continuous and discrete data examples, and you may not need both). • The “Take-Away” Boxes on most pages prompt you with comments; replace them with your project info. • When you see <> brackets, just highlight and type in your project information to replace the brackets and/or the suggestions/questions within the brackets. You’ll find several imbedded Excel Tools; you can “double click” on them to open the file and use. When you click back on the PowerPoint page, your data will show. On the Minitab examples, you can do your analysis off-line, and use the “edit”, then “copy” &/or “paste” functions to replace the template’s examples with your own data. Again, your BB/MBB coach can help ensure you select the right tools for your project. • Due to varying project requirements on Cost Benefit Analyses (CBA’s), please consult your local BB, MBB, QA, and / or Finance team regarding your project CBA, if applicable.

  4. <How Do My Customers See Me?> Define Step D1 Map Project Sample Comments (Delete this box prior to tollgate) This is set up as a table, so it will automatically adjust the box size to fit your text. Use your mouse to highlight the existing words, and replace with your project information. If you want to add or delete boxes, right click with your mouse on the desired table, and select “insert rows” or “delete rows”.

  5. Define Step D1 Project Charter Business Case: <How would you describe the project to your general manager?> <Why is it URGENT that you do this project NOW?> <How does this link to your functions’ key initiatives?> <What would happen if you don’t address this? “So What?”> <If the Project is successful, what will be the positive impact on the business?> Start / Stop Points for Project: <What are the boundaries for the project?> In Scope: <What processes, systems, products, services, channels, etc. will you consider in this project?> Problem Statement: <HOW MUCH of a problem is there? (use real data or leave blanks to fill in when you get the data)> <When was the problem evident? (dates that the data represents or was collected)> <What is the impact of the problem (time, $, customer satisfaction, etc.)> Out of Scope: <What processes, systems, products, services, channels, etc. will you NOT consider in this project? If any of these will be addressed in a later project, mention it here.> (Delete this box prior to tollgate) Defect, Unit, & Opportunity are identified in Measure, so you can wait to Measure fill these in. It’s convenient to have your whole project summarized on one page, so we included these here. As you complete your project, you should modify this page to reflect what you learn about your problem. Defect:<text here> Unit:<text here> Opportunity:<text here> Goal Statement: (“SMART”: Specific, Measurable, Attainable, Relevant, Timebound) <By WHEN do you want to have the improvement in place?> <How much of an improvement are you aiming for, e.g. XX% defect reduction, XX% cycle time reduction)?> <What measurable business impact will the improvement have? Type? Magnitute?>

  6. Define Step D1 COPIS 1. WHO are your primary customers?(From Step A) 2. WHAT does the customer receive? (Think of their CTQ’s) 3. What STEPS are Included in the Process today? (high level) 4. What is provided to START the process? 5. Who PROVIDES the input? Customer Output Process Input Supplier (Who) (Nouns) (Verbs) (Nouns) (Who) (Delete this box prior to tollgate) This page is set up with five tables. If you want to add or delete boxes, right click with your mouse on the desired table, and select “insert rows” or “delete rows”.

  7. Identify Step to Complete the Process Identify Step to Start the Process Use Diamond Shape for Questions Define Step D1 Process Map Optional Process Map Person or Function or Process Person or Function or Process Person or Function or Process Person or Function or Process Person or Function or Process • Delete this Box prior to Tollgate. • To build a flowchart: • You can either copy boxes shown here and replace text with your process info OR • Click on AutoShapes • Select “Flow Chart” for the Desired Shapes: • Diamond for Questions • Rectangles for Process Steps • Rounded Box for Start / Stop • To Draw Lines • Click on AutoShapes • Select Connectors, which will automatically link boxes you select. • Start your line at your “From” step • End your line at the “To” step • For Decision Diamonds, The “Good” process should drop down, and any rework or bad steps should go to the side. Different Columns Can be used to Show different Process owners throughout The project. You can delete columns if you don’t need as many as shown here. Input your first process step here You can can also widen remaining columns if necessary to fit your process map on the page. You can copy these boxes and insert your process step information in them. N Y • Map Validated by: • <Name> • <Name>

  8. Define Step D1 Change Stakeholder Analysis Optional Page (Delete this box prior to tollgate) This is set up as a table, so it will automatically adjust the box size to fit your text. Use your mouse to highlight the existing words and replace with your project information. If you want to add or delete rows, right click with your mouse on the desired table, and select “insert rows” or “delete rows”. For each stakeholder move your cursor to the desired box and type “X” for current state and “O” for desired state. • * When Populating the Stakeholder, consider the ARMI: • A= Approver of team decisions • R= Resource or subject matter expert (ad hoc) • M= Member of team • I= Interested Party who will need to be kept informed X = Where this Stakeholder IS TODAY on the Project O = Where this Stakeholder NEEDS TO BE on the Project

When you click back in the PowerPoint slide, your info will show here. CTQ Translation Matrix (Delete this box prior to tollgate) To modify this CTQ Translation Matrix, use your mouse to highlight the existing words, and replace with your project information. You can copy these Symbols and paste on CTQ relationship chart above.      

  11. Measure Step M1 Performance Standards CTQ Performance Standards (Delete this box prior to tollgate) (If you prefer, we have an alternate layout for this page in the appendix). This is set up as a table, so it will automatically adjust the box size to fit your text. Use your mouse to click on the desired field, and type in your project information. If you want to add or delete rows, right click with your mouse on the table, and select “insert rows” or “delete rows”.
