Research Background RESEARCH PROBLEM • Most companies today, have left the final choice of which which Planning, Execution and Continuous improvement (PECI) methods and which IT systems to support these to Business Units because BUs are: • Responsible for continuously improving on their result. • In the best position to decide which methods & systems best meet their specific requirements. • Normally responsible for pay for these. • No wonder BU’s have resisted most attempts to standardize or centralize IT and PECI’s …
Research Background RESEARCH PROBLEM • However, not standardizing and leveraging Best Practices and a common IT platform, has major negatives for the Company as a whole… • Providing Support to multiple IT platforms and different Improvement methods is a nightmare for Centralized functions and very costly • Ensuring fast and reliable integration of data between different systems is a major challenge and occupies valuable management time every month • Business Processes cannot be standardized to enable fast and accurate transactions. • Best Practices are not shared and results achieved are not duplicated
Research Background RESEARCH QUESTIONS Q1: Is it possible to find a "one-solution-fits-all" both in rules and ERP technology when it comes to planning, execution and improvement of operations especially considering the many specific local considerations resulting in "we are different”)? Q2. Even if it was possible to theoretically find such a solution that could meet most business requirements, would it be possible to get buy-in from regional and plant managers under pressure to improve performance & reduce costs to test such a solution?
Research Background RESEARCH METHOD • Literature Review to identify which companies have tried and succeeded and which not and Why? • Consultation with Experts to determine if a “One-Solution-fits-all” solution design was possible and then whether such a solution can be implemented within a standard ERP System (the hypothesis to be tested) • Followed Action Research method using “Plan, Do, Review & Act” cycles to validate and continuously improve hypothesis

Operational Excellence Acceleration Challenge What blocks a company such as ABB from identifying and spreading best-practices, learnings and results effectively in a big organization? Need Action Have a way to Roll -out best-practices efficiently & effectively Standardize our improvement approach The “Best Practice” Standardization Dilemma Objective Because: Each BU/Factories is different which mean there are no “one-solution-fits-all” that can be rolled out Ensure leverage of Best-Practices in all Business units Conflict Need Action Have a way to ensure out- standing result in each BU Customize an improvement approach for each business unit Really?
Operational Excellence Acceleration Challenge Despite the many differences between the plants where TOC+LEAN were implemented, it seemed to deliver similar results without any significant differences in the “what” and “how to”… Need Action Standardize our improvement approach Roll-out best practices effectively Resolving the Standardization Dilemma: Objective Ensure leverage of Best-Practices in all units Need Action Develop approach with target unit personnel each time Ensure out- standing result in each unit Direction of solution: Use TOC to focus & synchronize Planning, Execution & Cont. Improvement solution (TOC + LEAN) and an participative engagement approach for getting contribution and consensus

ABB’s ERP System reality after years of acquisitions and empowered BU and Regional IT decision making.. • As a result of numerous acquisitions, ABB at one time had more than 500 ERP systems and 70 different ERP brands in operation across its businesses. • Most of the factories and distribution centres were also using in-house developed Spreadsheets and Databases for supporting their preferred Planning, Execution and Continuous Improvement Methods • Integration of systems and data (and support) had become a nightmare and major risk to the business. • In late 2006, a decision was made at the ABB board, to embark on a (challenging) journey of standardization on a common IT / ERP Platform (or at least range of platforms) and simplification based on “best-practices”. • The initiative was titled “One-simple-ABB” or “OsA”.
ABB’s “One-simple-ABB” decision and consequences... Press Release in March 2007 “Today, ABB signed a strategic agreement with the German-based ERP provider, SAP to help deploy common SAP ERP software through its global operations to help unify and simplify some of ABB’s most important business processes. The OsA initial target is one ERP per country, and ultimately one ERP platform per region for all of ABB that would enable a high degree of standardization in the human resources, finance and administration and corporate governance functions as well as in the operational excellence “best-practices” Yes, BUT.... Would it really be possible to find and get agreement that a “One-simple-ABB” solution was possible for managing the diversity and complexity of ABB’s 300+ factories?
The Operations dilemma in supporting ABB’s global “One-Simple-ABB” objective? The “One-Simple-ABB” Dilemma Need Action Deploy a common ERP platform across ABB and limit selection of SCM & MES systems Efficient and fully integrated Finance, HR & OPS business processes across ABB Objective Because: Each BU/Factory is unique and using a common ERP platform or limiting choices in SCM / MES methods & systems will jeopardize results and or ownership Create long term competitive edge in our industry Need Action Continuously Improve customer service and sales through efficient & effective operations Allow each site to develop own / use 3rd party ERP, SCM & MES systems
The Operations dilemma in supporting ABB’s global “One-Simple-ABB” objective? The “One-Simple-ABB” Solution for Operations Need Efficient and fully integrated Finance, HR & OPS business processes across ABB • Direction of win-win solution: • Get agreement that TOC can provide “one-solution-fits-all” • Find a way to Modify SAP R3 to support TOC (TOC Planning, Execution & POOGI rules). • ABB to launch a “TOC in SAP” initiative to validate above hypothesis Objective Create long term competitive edge in our industry Need Action Continuously Improve customer service and sales through efficient & effective operations Yes, BUT… Q1: Would it really be possible to define a TOC “One-solution-fits-all”? Q2: Would it really be possible to modify SAP to support this solution?

Under such circumstances, quoting fixed lead times is very likely to result in missed due dates resulting in poor DDP. Due-dates given by the sales force/planning are (almost) always met even during periods of capacity overloads (Target: 99% DDP) • It is relatively easy to meet all due-dates when the commitments are given based on actual planned loads on the CCR(s) and S-DBR and BM are in place to control release & align priorities. • The ERP systems can be modified to provide (within mins) a safe due date based on CCR(s) planned load + ½ Production Time Buffer (if CCR is about in middle of flow) Safe Due-date are given according to first available slot on CCR(s) + ½ Production Time Buffer The ERP system is modified to provide Safe Due Date based on CCR Planned Load + ½ PTB within minutes and Sales/Planning is trained to use it.

Edge) • . The target levels of RM & PP inventories held are continuously monitored and when needed are suitably modified (not too much/too little) • TOC;s Dynamic Buffer Management & Replenishment of RM & PP Inventory, is a robust mechanism that enables setting, replenishing & adjustment of inventory targets, according to the actual level of demand & supply ensuring low levels of inventory& high availability. • Most ERP systems do not provide a mechanism for auto resizing inventory target levels based on actual changes in demand/supply Target Levels are sized based on Max Demand within Reliable Replenishment time (Rt=OLT + SLT) Inventory levels are maintained by replenishing on actual consumption & resizing on buffer penetration The ERP system is modified to enable DBM & TOCR functionality

Defining, communicating & validating the proposed ERP change using S&T structure 2.1 1 3.1.1 4.11.3 (Planning) TOC RELEASE CONTOL (S-DBR) DETAILS Reliability/Availability Competitive Edge ABB Goal: Profitable Growth Remarkable Due Date Perf & Availability TOC’s RELEASE CONTROL (S-DBR) to control WIP and improve T, DDP & LT TOC Release Control to prevent Over-production 4.11.3 • Having too many orders on the shop floor masks priorities, promotes local optima behavior and therefore prolongs the lead-time and significantly disrupts due-date-performance (DDP). • Having too little orders on the shop floor will cause starvation of CCRs and cause lost production and potentially missed due dates (jeopardizing building of a “Reliability” Comp. Edge) • . The shop floor is populated ONLY with orders that have to be filled within a predefined horizon. • In traditionally run plants touch time is a very small fraction (<10%) of the lead time. • Vast experience shows that, in traditionally run plants, restricting the release of materials, to be just half the current lead time before the corresponding due date, leads only to good results and to no negative ramifications* (lead time shrinks to less than half, DDP improves considerably, throughput goes up and excess capacity is revealed). These results are achieved irrespective of whether or not a bottleneck exists. • * Except for environments which are dominated by heavily dependent set-up matrixes. Those environments have to be dealt in a different way. For each group of products currently having similar lead times, a buffer time is set to be equal to 50% of the current avg lead-time. Orders are released to the floor only a buffer time before their committed due-date, and if all materials are available. (WIP frozen until its time arrives). The ERP system usage is modified to support S-DBR release control and automatic material availability check.

Defining, communicating & validating the proposed ERP change using S&T structure 2.1 1 3.1.1 4.11.4 (Execution) TOC SINGLE PRIORITY SYSTEM DETAILS Reliability/Availability Competitive Edge ABB Goal: Profitable Growth Remarkable Due Date Perf & Availability TOC’s Buffer Mgt (BM) as synchronized SINGLE PRIORITY SYSTEM Single Priority System to Synchronize Execution 4.11.4 • Hectic priorities (hot, red-hot and do-it-NOW) cause chaos on the floor • Even when material release is properly choked, not having a priority system can cause some orders to still be late.. The shop floor is governed by a simple, yet robust, priority system • Vast experience has shown that when work is released according to set time buffers, excellent results are obtained by using a crude priority system that is based solely on the time lapsed since the release. • Buffer Management (BM) is setting priorities only according to the degree the buffer-time is consumed(four color code system - green: less than one third of the buffer time passed is lowest priority and black: more than the time buffer passed is the highest). TOC Buffer Management is the ONLY priority system used on the shop floor. The ERPsystem (and MES/RFID systems) are modified to ensure the Purchase Order List, “Work-to-List” and Distribution Shipment List are prioritized based on buffer status (1st Black, 2nd Red, 3rd Yellow, 4th Green)
4.11.4 Single Priority System to Maintain Execution Synchronization Tactic Target Levels are sized based on Max Demand within Reliable Replenishment time (Rt=OLT + SLT) Inventory levels maintained by replenishing on actual consumption & resizing on buffer penetration SAP Customer Production Orders do have “Due Dates” Sample Screen for showing Buffer status (Priority) of each order and enabling capturing of reason codes for “black” and “red” orders Stock Replenishment Orders do not have “Due Dates”

When materials release is restricted, the only work centers that have work-in-process piling up in front of them are the real CCRs. • CCRs can be identified also by recording “what black & red orders were waiting for?” • In most of the cases additional capacity can be exposed by better EXPLOITATION like: • - Ensuring that CCRs do not take lunch or shift change breaks, • - Offloading work from the CCRs to less “effective” work centers that have ample excess capacity, • - Using LEAN /Six Sigma techniques to shrink the set-up time/reduce variation on the CCRs, • - ELEVATING capacity with overtime or capex approval for the CCRs, etc. For all Red & Black Orders and Stock Buffers, Production Supervisors/workers/purchasers record “what was black/red order waiting for?” CCRs are identified and effectively removed through focused process improvement / elevation to the extent that most loaded resource has at least 20% protective capacity. The ERP (and MES) systems are modified for POOGI.
4.11.5 Focusing Mechanism for Process Improvement/Elevation Tactic For all Red & Black Orders an Stock Buffers, Production Supervisors record “what was black/red order waiting for?” CCRs are identified and effectively removed through focused process improvement / elevation to the extent that most loaded resource has at least 20% protective capacity.

TOC in SAP at ABBResults from Brno (Czech Republic) and Vaasa (Finland) “After analyzing SAP recommendations and data from nearly 2 months, we are confident that the the TOC rules were implemented correctly and that we are now confident that we can switch of our Off-line & 3rd Party systems. The new Dynamic Buffer Management Functionality enables us to react quickly to changes in inventory values, which was not possible earlier, as we didn’t have time to monitor values manually. We are very happy, are continuing to use the functionality and will be expanding it to other product lines” Operations Managers Factories in Brno and Vaasa
TOC in SAP at ABBNext Steps • Implemented "TOC and SAP” now in 8 factories: • in Brno, Czech Republic • in Chonan, Korea, 2 factories • in Vaasa, Finland, 2 factories • in Baroda, India • in Przasnysz, Poland, 2 factories • And planning the implementations (in the work queue) • In Vaasa, Finland, 3rd factory • in Dalmine, Italy • in Ratingen, Germany. Has “SDBR in MES” • in Xiamen and Beijing China • in Skien, Norway. • …until all 300+ factories are reached…
Research Conclusion • The “TOC in SAP” initiative, showed that the ambitious goal of “One-Simple-ABB” can be achieved even in the management of operations (Planning & Execution and Continuous Improvement) in complex and different operational conditions. • The partnership between ABB and Goldratt Research Labs made it possible to: • Define a ROBUST enough TOC Planning, Execution and Continuous Improvement solution that could cope with all the variations and complexities of 300+ factories • Define a SIMPLE enough TOC Solution which could be supported with relatively small modifications within a standard ERP system such as SAP. • Break new ground by using the Strategy & Tactic Tree to define, communicate and get buy-in for the new TOC solution in a way that focused and accelerated the achievement of consensus and development of the required SAP functionality…which is also accelerating all new SAP implementations • Deliver this project and its associated results in a record time for SAP solution design, development and testing in less than 9 months….

CASE STUDY 2Finding & Testing a solution to SHORTAGES & SURPLUSES within Book Publishing Presented By: Dr. Alan Barnard (CEO Goldratt Research Labs, TOCICO Chairman 2003-2006) Date: 27th August 2009
Presentation Outline • Generic Research Problem • Extent and Consequences of Shortages & Surpluses • Cause(s) & Direction of Solution • Case Study: Random House Publishing • Publishing Industry Background • Random House Company Overview • Phase 1: Quantifying the Extent, Consequences & Causes • Phase 2: Finding a Solution • Phase 3: Testing the Solution • Research Findings • Future Research
Research ProblemExtent & Consequences of SHORTAGES • How many of YOU frequently don’t find what you want at a SHOP? *Either because the retailer was “Out-of-Stock” (OOS) or it decided not to carry the item you wanted? • What is YOUR (consumer) response to this SHORTAGE? • Come back later to same retailer to buy same product? • Buy a similar product from same retailer and same supplier? • Buy a similar product from same retailer but different supplier? • Go to other retailer to buy same product? • Do not buy anything? What is the consequences of this SHORTAGE on: SHOP BANK CONSUMER SUPPLIER
Consequences of SHORTAGES on Profitability For Book Publisher and Retailer… Quantifying impact of 1% Lower Sales Volume on Net Profit INSIGHT: 1% Lost Sales = 10% reduction in Profits BELIEF: Lost Sales is not significant (2 – 3%) since today, consumers that want our products can in most cases find it somewhere. FEAR: Is it really worth it to invest in trying to further reduce Shortages? CHECK: How do we know shortages (out-of-stock) is really “only” 2-3%? Does it match our experience as Consumers?
