1 Utilization of Six-Sigma Methodology for Lean Operating System Monitoring In Product Development Area Cristiano Marques de Oliveira Delphi Automotive Systems Packard Electrical / Electronic Architecture Division

2 Lean Implementation Challenge Expand the use of Lean Manufacturing concepts to Product Development related areas o Improve processes flow and connectivity Eliminate the seven types of waste on product development process o Correction o Overproduction o Movement of Information o Motion o Waiting o Inventory o Processing The complexity of the waste identification task can increase when the product development process is considered! 2

3 Lean Operating System Elements Process map with the connections between areas Performance metrics (Quality Volume Cost) Q: with quality V: on time C: at cost OK? OK? OK? Start Quality Volume Cost Return Visual management panel Activities scheduling system 3

4 No Defects Culture Culture Highlights Don't pass defects for the next step, including missing information. Stop Culture Do not start the next process if there are missing inputs, run risk assessments, evaluate and determine whether you can proceed. Fix Quick Culture Immediate feedback and resolution of the source of QVC issues. Visual Culture Uses simple visual controls for managing processes. QVC Ownership Culture All employees should be devoted to achieving the goals of QVC as well as the cost templates. 4

5 Why Use Six-Sigma Method? Standardize monitoring and avoid functional areas duplicate efforts for: Metrics collection and method definition. Visual management panel compilation. Define Measure Control Analyze Improve 5

6 DEFINE Understand the monitoring process including collecting QVC metrics and visual management panel creation Tools used: High level process map (SIPOC) Supplier Inputs Process Outputs Customer Requirements Requirements Operating System Implementation Team Functional Area Leadership Product & Process Development Flow Lean Definitions Strategic Plan With connection between areas With inputs and outputs per pipe With QVC strategy With definition for visual management panel With management routines frequency With scheduling details With implementation lead-times With names of area representatives With QVC metrics implementation goal Product Development QVC map Collect and compile QVC metrics and update the Visual Management Panel Visual Management Panel available with QVC data QVC metrics installed Visual Management Panel available Scheduling System in place With collect plan defined With owners names With updated data With defined updated frequency With charts per functional area With each activity due date With owner name With project name With read access to activity owners Functional Area Program Managers and activities owners 6

7 MEASURE Measure the gap to meet the QVC metrics implementation goal (strategic plan) for the product development process. Tools used: Bar chart Initial Situation 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% NOK OK Type OK NOK Q 7 25 V C 3 7 Goal 91 Q V C 7

8 ANALYZE Define the main root cause for the duplicated effort. Lack of a common systematic for monitoring system implementation, including metrics and visual management panel. Tools used: Fishbone Material Man Because this kind of knowledge is not listed on functions description Because it is not the functional area focus have an IT tools specialist Because this knowledge is not mandatory to exceute the area activities 5 whys Lack of knowledge on IT tools available Duplicated Effort for Metrics and Visual Controls implementation Because there is no one responsible to create a common process Because each area is responsible only to provide the data no matter the format ause there is no guide or system to be followed for ess Each area creates its own independente control Methods Machines 8

9 IMPROVE Classify potential solutions according to selection criteria and choose the one that better fits to lean culture. Tools used: Decision matrix Solution Proposals Σ Simplicity Develop Internally Easy to use Investment Automatic Graphs Easy to Standardize Less data consolidation Excel spreadsheet locally stored Excel spreadsheet stored in network Excel spreadsheet stored in Share Point Share Point site with lists and libraries Share Point site integrated with MS Access Share Point site integrated with XML forms Share Point site integrated with standard XML form

10 Solution Details Create the Share Point site for data collect Upload project documents into site library Input some information to save the document Reports and graph available based on input information Advantages: Place to store the activities history data Structures data to generate automatic reports and graphs No specific IT programming required Advantages: Small user routine impact Flexible for expansion No documents format change required All historic data stored in one place Advantages: Few simples question to complete to upload a new item Data upload is part of day-by-day job (currently only communicate by ) Advantages: Reports always updated with last input data No duplicated efforts to create a report or graph (only once) Full history of Project activities 10

11 Standard Measurement Units Quality: Based on the document upload loop and reason for upload Volume (Schedule Attainment): Base on the actual date filled-out in document upload form Cost: Based on cost check answer in document upload form 5-Excellence 4-OK 3-OK with comments 2-Not OK/No Info 1-PROBLEM Q V C Completed at first time Completed but not at first time Completed with rework/revision First time not successful Not completed and revised Document published on time On time but not published yet Finished late No due dates (no planning) Late and not finished <= Target and finished <= Target on going Pending document No target available > Target 11

12 CONTROL Monitoring system automatically updated based on projects documents upload Work instruction published and training sessions done Functional Area List the documents to be monitored and filed Lean Team Define what documents creates each QVC metric Program Mgt Input the due dates for activities evidences uploads Program Mgt Insert projects to be monitored on Project Master List Functional Area Upload the project documents in the system QVC Monitoring Automatic metrics and visual controls 12

13 Conclusions Product development can benefit from the use of lean optimization tools and methods applied in manufacturing. Each new product/process development is unique in its contents, but the work done in each project is similar. Major improvements expected in the medium term, due to the time required for the incorporation of new culture. The use of the lean operating system combined with the cultural change can increases the waste visibility in product development area so they can be properly eliminated. 13

15 BACK-UP SLIDES

16 7 Types of Waste Correction Re-designs, additional testing, audits, correcting documentation, inspection, etc. Overproduction Completing a process earlier than is needed, producing more than is needed, or processes not being synchronized Movement of Information Material or information that is moved from one location to another, such as: o o o Unnecessary handoffs s or creating redundant status reports Multiple locations of storage for the same information Motion Usually focuses on man and machine Attending unnecessary meetings, reviews, tours, etc...without any action Waiting Waiting for decisions or information including approvals or not having the right information I order to start a process Inventory Excess information or material waiting to be processed Information waiting for a resource to begin work Processing Redundant tasks, designing new components rather than using existing ones, or lack of standardization 16

17 Lean Principles Make right part, right time, right volume Short lead time Built in quality High capacity utilization High resource utilization 17

18 Policy Declaration Discipline All information is on time, accurate and correct before starting work. Escalation is used assure compliance Efficient Quality, Lead time and Cost of each process step is tracked and continuously improved to benchmark levels. Effective All Program Imperative commitments are met. Problem Prevention A culture of perfection by anticipating and identifying defects before they occur. Perfect A culture of not passing along defects that are detected to assure 100% quality to downstream processes & customers. On Time Master program schedule exists and is respected, with visual controls and achievement plans in place. At Cost Total product cost is monitored and achieved by the process. Capability All People are developed and trained to follow the OS, and their time is used efficiently. 18

19 QVC Gates Quality The gate evaluates the quality of the work that is performed in that process It should identify mistakes, omissions, and sub-standard work for each output It requires that a standard be developed and a means of evaluating the work against the standard (checklist, calculations, computer program) Volume (Schedule Attainment) The gate evaluates the schedule attainment of the work performed in that process It requires a clear definition of when this process step begins and when it is completed and those events must be measurable Cost The gate evaluates the cost variance (+/-) related to work performed in that process against the business case or budget allocation for that work It requires a clear definition of how, if at all, the process directly impacts product cost, capital cost, or development cost The QVC gate can omit the cost evaluation if the process step does not impact cost 19

20 Why use Visual Controls Allows you to passively see status OK or not OK Drives immediate action Highlights capacity issues and supports reallocation of resources Identifies roadblocks Reminds you what to work on Motivates you to hit targets (don t want to be red ) Provides you a means to monitor process control Encourages system/process improvements Promotes awareness of process and status Tracking of QVC expectations Possibly used for predicting QVC issues 20

21 Monitoring Systematic OK? OK? OK? Start Quality Volume Cost Return QVC => Status of our Outputs Monitoring => Visual Control of QVC s Management Routines => Drive Action based on QVCs 21
