CD-ROM describes Chick-fil-A’s decision making process in selecting a new Point of Sale System (POS) based on either Windows NT or Windows CE systems
Excerpt from the Case Study:
Mike Erbrick, Director of Restaurant Information Systems at Chick-fil-A, was given the responsibility of converting the restaurant’s point of sales (POS) systems from a proprietary EPROM based system to a newer system. This changeover had an investment impact of approximately $3.29 million based on the differences in the costs required to implement the various POS systems being considered, which could be as high as $15,000 per outlet depending on the system chosen and store layout. Within its more than 700 outlets, Chick-fil-A averaged about 8 POS systems per store compared to the two or three systems per store used by other quick-service restaurant chains. The number of POS systems gave rise to additional confusion for the kitchen staff because they could have six to eight orders arriving simultaneously on the Kitchen Display System (KDS) screens. Thus, the new system had to be extremely efficient and scalable to meet the needs of individual stores. Perhaps most importantly to the store owners using the system, who are compensated based on their sales figures and net income, the sales data should be relayed to Chick-fil-A’s corporate headquarters accurately and reported back to each store in a timely manner.

Problem studied: At Vogtle, plant manager Robert Moye and engineers Patrick Conley and Kerry Walton were faced with two alternative methods of improving the performance of their counterflow natural draft cooling tower. The source of the tower’s underperformance seemed to be the water distribution across the tower’s area. The managers and engineers were at the decision point: they could either revert to the configuration that was known to produce a tower efficiency of 91% or modify the tower based on John Cooper’s new recommendation.
- Places students in the position of power plant engineers trying to make a decision which will improve the cooling tower’s performance, consequently affecting overall power plant efficiency
- Makes students use the evidence provided and their intuition to support their decision for modification of the tower
- To teach the impact of cooling tower water distribution on air flow and exiting air temperature, both of which affect cooling tower performance

Problem studied: With the introduction of Powertel’s new 3600 minutes for $40 rate plan, the growth of cellular subscribers jumped 40% in one month. This growth put a tremendous strain on the existing cellular network structure. An example was at the intersection of Highway 280 and Interstate 459 in Birmingham, AL, where users experienced many dropped calls. The choices to resolve this problem were to either install a new tower on a nearby hill or to add equipment to the existing tower on top of the Sheraton hotel. The costs for these options ranged from $150,000 to $700,000.

Problem studied: Wellborn Cabinets is a family owned business that was founded in 1961. The company’s headquarters and largest factory are located in Ashland, AL and occupy over two million square feet, building about 5,000 cabinets a day. Wellborn primarily supplies builders and dealers who work with customers to design kitchens and dressing and entertainment suites, with a typical order of 20 cabinets containing 15,000 pieces and costing about $15,000. Wellborn began to use Enterprise Resource Planning (ERP) systems about 10 years ago to manage its business.
Wellborn Cabinets adopted a system called Symix, a full ERP system, in 1998. Although Symix had a complete set of modules, all of which were used across all of the company’s departments, each plant used its own database so two plants that were close together were not linked on the financial end. As a result, spreadsheets were used to merge data and engineers had to maintain 580,000 discreet bills of material. Shopfloor workers knew the bills of material were not accurate and paid little attention to them, instead building the cabinets using “tribal knowledge”, which led to frequent returns and many defects. Marketing, engineering, and training issues were also not addressed adequately.
- Understand that a large Enterprise Resource Planning (ERP) package can be successfully implemented by a medium-sized company in a reasonable time frame with strong benefits
- Develop an appreciation for the SDLC (system development life cycle) process for Management Information Systems and how it was used at Wellborn Cabinets
- Understand the use of software and business consultants in implementing an ERP system

Problem studied : Larsen & Toubro Limited (L&T) has contractors and field offices spread out all over India and abroad. Currently when a remote job has a work order that it cannot approve it has to be sent to the region office and the main headquarters when applicable. The software that the remote sites use to request work orders is called Cema, but it does not offer an automated solution for synchronizing it records with the main database. Currently the process of getting a work order approved is a manual process and could mean waiting a day for approval. Before a work order is approved all the resources at the remote site sit idle, waiting for approval. So reducing the approval delay will also reduce the time equipment sits idle at the job site.

Problem studied: There were three main problems faced at the inspection stage of induction pressure welding process
The first problem was with the inspection time of the welds. The time taken for the cooling and inspection is more than the time for set up and the welding. This made the processing stagnant at the inspection stage in the production environment. So BHEL is looking for a faster method of inspection.
The second problem encountered by the operators at inspection was the inaccessibility of welds. It was tough to access some areas of piping for inspection.
The third problem was with the pasty welds or kissing bonds. When the crack surfaces stay in very close contact with each other then the bond between the two surfaces of the crack is called a kissing bond. This is a very dangerous bond. The welds appeared to be fused and pass the ultrasonic inspection but failed at the work site. Lack of bonding and mismatch are the types of defects commonly appearing on these welds.
- The case study briefly explains the induction pressure butt welding process and issues with it.
- The case study underlines the importance of in-situ weld inspection
- Understand the NDT techniques used for in-situ inspection of induction pressure welding
- Analyze the different possible alternatives applicable to the problem
- The students get to choose one possible alternative and defend it and also get to know how to solve real-world problems
