To link these stations with a total area grid, a new method of car- rying the power lines using ornamental tubular poles instead of towers had been adopted. Moren had had no previous op- erating experience with poles and decided to subcontract the design engineering, fabrication, and erection of the new line. For the first phase of engineering design, Mr. Carter, the vice president of supply, faced the responsibility of de- ciding with which supplier the business was to be placed after his staff had developed the information needed. He was aware that Moren had only three years in which to complete the entire project, and yet he had to ensure high- quality work. joh77899_ch06_.indd 156 6/9/10 9:40 PM Chapter 6 Need Identifi cation and Specifi cation 157 COMPANY BACKGROUND Moren Corporation, established in 1895, was one of the largest power utilities in the eastern United States.

It serviced a highly industrialized area of 10 fossil-fueled plants. With assets of over billion and demand dou- bling every decade, it had already earmarked funds to in- crease its kilowatt capacity from 8.4 million to 13 million over a four-year period. The company was well known for its advanced tech- nology and its good public relations. Both purchasing and engineering departments were centralized and located in the head office in the area’s largest city. The new con- struction program was a heavy strain on both the profes- sional and financial resources of the company, placing increased emphasis on the use of qualified people and suppliers outside the corporation.

TRANSMISSION LINE BACKGROUND Although Moren was stepping up its older lines to 230 kV, by management decision and in accordance with the tech- nological trend, 345 kV was adopted for the new line. It was to link the new generating stations in Addison, Smithfield, and Mesa Valley with the area grid, some 140 miles in total. Until now, Moren had used structural steel towers ex- clusively for carrying its power line. These were strong but visually prominent and attracted adverse comments from a public daily growing more aesthetically sophisti- cated. A relatively new development in the transmission field was the introduction of the ornamental tubular power pole.

Approximately 2,000 miles of line using these poles had been installed with good success in various parts of the country. Most installations were relatively short sec- tions in densely populated areas. A line using poles costs twice as much as the conventional towers but is still sub- stantially cheaper than underground installation. Con- scious of the great strides made in power pole design and use, Moren management decided to specify poles for the new lines. Because of the volume of conversion and projected ex- pansion work, Mr.

Carter and the project engineers knew that the tower manufacturers and erection companies with whom they had dealt in the past would not have the ca- pacity to handle all the elements of the new pole concept. Furthermore, with no experience in 345 kV or pole sus- pension, Moren had to reply on the know-how of others for the new line and needed the services and guidance of competent subcontractors. The total job involved three major phases. 1. Engineering design called for layout as well as a func- tional pole specification and project guidance.

2. Pole manufacture involved a manufacturing proposal consisting of a specific design to meet the functional specifications as well as manufacturing volume and schedule deadline capabilities. 3. Pole installation involved excavation, foundation set- ting, pole erection, and line stringing. Preliminary cost estimates for the total project were as follows: a.

Phase 1—Engineering: ,500,000–,800,000 b. Phase 2—Pole manufacture: million c. Phase 3—Installation: million Mr. Carter and the chief engineer were not satisfied that any individual supplier could handle the total contract well. They decided, therefore, to subcontract each phase to a reliable source of high expertise within that phase, so that optimum overall benefits would accrue to Moren.

The first sourcing decision dealt with the engineering phase. DESIGN ENGINEERING SELECTION All through the spring and half of the summer Oliver Dunn, the buyer, worked with the transmission engineer- ing section of the system engineering department of the company to establish parameters and locate a suitable de- sign source. By late July he was able to make his recom- mendation to the director of purchases (see Exhibit 1). It was normal practice at Moren to provide a very brief summary for the director of purchases on all major con- tracts. A large file containing detailed information was built up by the buyers and purchasing agents involved.

Normally, some preliminary discussions were held as the project progressed, so that Mr. Carter was reasonably in- formed by the time the official recommendation was pre- pared. Should he wish to see more information he could request the file at any time. All three of the engineering firms considered were large and engaged in a wide variety of engineering con- sulting services. Travers & Bolton (T&B) and Crown Engineering (CE) had both done considerable work for Moren in the past and had performed satisfactorily.

Pettigrew Associates had its head office in New York and maintained branches in 10 American cities. Pettigrew employed over 3,800 people, had a good credit rating, and had annual sales in excess of 0 million per year. Moren had never used Pettigrew in any of its projects. All three engineering firms had some tubular pole experi- ence with short-line sections in other parts of the country. joh77899_ch06_.indd 157 6/9/10 9:40 PM 158 Purchasing and Supply Management Moren Corporation was building three additional gen- erating stations to serve the rapidly expanding energy market. To link these stations with the total area grid, a new method of carrying the power lines using ornamental tubular poles instead of towers had been adopted.

Moren lacked experience with poles and decided to subcontract the design engineering, fabrication, and erection of the new line. [For company background and line projection Aside from the design requirements, the consulting engi- neering firm was also expected to evaluate the bids from pole manufacturing and erection subcontractors. Additional Information 1. The transmission section of our general engineering department is unable to perform the design work of all the planned transmission work for the next three years, and it is necessary to contract some portion of this work. Travers & Bolton are already assigned the conversion of the 120kV to 230, and it is recommended that this 140-mile Addison-Smithfield-Mesa Valley 345 kV be contracted to some competent engineering firm.

2. We had sessions with each of the three below men- tioned engineering firms to acquaint them with our needs and learn of their capabilities. The work they will perform is as follows: Make routine sections; make subsurface investigations; make electrical hard- ware and general project designs; and furnish miscel- laneous specifications, drawings, and technical data required to procure the right of way, hardware, struc- tural steel, and the awarding of contracts for construc- tion. It is estimated this work will total 12,300 labor- hours. There will also be approximately 4,000 worth of computer services and general out-of-pocket expenses in addition to the labor-hours.

Total cost will be influenced by the capabilities and productivity of the company chosen, and, therefore, Pettigrew may not cost us any more; it is the desire of Moren management to have Pettigrew perform such a job with Moren as our first experience with them. Both T&B and CE have done considerable work for Moren. Case 6–2 Moren Corporation (B) joh77899_ch06_.indd 158 6/9/10 9:40 PM

Effective Supply Methods for Managing MRO Requirements

Introduction
Maintenance, Repair, and Operations (MRO) supplies are critical for any organization focused on operational efficiency. The effective management of these supplies utilizes various strategies, considering the importance of availability, cost, and supplier reliability. This paper discusses effective supply methods for MRO requirements, comparisons of acquisition strategies between resale and component parts, the rationale for acquiring by brand, the pros and cons of performance specifications, the distinctions between standardization and simplification, identifying strategic requirements, and the environmental impact of acquisitions.

Effective Supply Methods for MRO

1. Centralized Purchasing: Centralized purchasing consolidates MRO procurement in one department, improving bulk purchasing power and reducing costs. It allows for better contract negotiation, ensuring consistent pricing and availability (Duffy & Flynn, 2003).
2. Vendor Managed Inventory (VMI): In a VMI arrangement, suppliers manage MRO inventory levels based on their analyses of consumption patterns. This reduces the burden on internal staff and ensures that stock levels are maintained efficiently (Ellram et al., 2004).
3. Just-In-Time (JIT) Delivery: JIT minimizes inventory costs by ensuring that MRO supplies arrive just when needed. It requires strong supplier relationships to maintain reliability and timeliness (Wade, 2003).
4. Standardization: Implementing standardized materials and components across the organization simplifies inventory management and reduces the variety of MRO items needed. This can lead to lower costs and streamlined operations (Ritzman et al., 2004).
5. E-Procurement: Online tools streamlining the procurement process can lead to significant time and cost savings. These platforms often allow organizations to compare prices and availability instantaneously (Contino, 2002).
6. Consignment Inventory: This method involves suppliers owning the inventory until it is used, which can reduce immediate cash outflow for MRO materials while ensuring that necessary supplies are readily available (Smeltzer & Ogden, 2002).

Resale Requirements vs. Parts, Components, and Packaging Acquisition

Acquiring resale requirements involves fulfilling the needs for sold products without interference in upstream supply chains. On the other hand, acquiring parts, components, or packaging includes dealing more intricately with supply chain logistics, quality controls, and production schedules. The acquisition of resale items focuses on vendor relationships and seasonal demands, while parts and components require stringent quality assessments and can often be tied closely to production cycles (Axelsson & Wynstra, 2002).
The differences in these acquisition strategies also emphasize inventory management and cash flow impacts. Resale items may revolve around broader market dynamics, while parts and components procurement often has to fit precise specifications and reliable timelines to meet manufacturing goals.

Acquiring by Brand

Supply professionals may choose to acquire by brand for several reasons:
1. Quality Assurance: Established brands often have a reputation for quality, leading to reduced risks associated with purchasing substandard goods (Duffy & Flynn, 2003).
2. Brand Loyalty and Trust: Reliable brands foster trust among their users, which is crucial when making purchasing decisions, especially in critical operations requiring reliability (Ellram et al., 2004).
3. Warranty and Support: Brand-name products often come with warranties and customer support that can save costs associated with failures and performance issues (Ritzman et al., 2004).
The downside to brand acquisition can be the increased cost and potential monopolistic practices, which might lead to higher overall procurement expenses.

Specifying by Performance: Advantages and Disadvantages

Advantages:
1. Flexibility: Performance specifications allow for innovative solutions, enabling suppliers to propose the best means to meet specific performance outcomes (Wade, 2003).
2. Encouragement of Innovation: Specification by performance encourages suppliers to develop new technologies and methodologies, potentially leading to improvements beyond conventional solutions.
Disadvantages:
1. Complexity in Evaluation: Performance specifications can be challenging to evaluate, leading to discrepancies in bids and supplier capabilities (Smeltzer & Ogden, 2002).
2. Risk of Unsuitable Bids: Suppliers may interpret performance specifications variably, risking the submission of non-compliant solutions (Contino, 2002).

Standardization vs. Simplification

Standardization refers to creating uniform processes, materials, or components across various operations, enhancing compatibility and streamlining supplies. In contrast, simplification narrows down the variety of items for easier management. Standardization maintains a broader focus, while simplification aims at optimizing specific processes (Ritzman et al., 2004). Both strategies can lead to cost savings, but organizations must assess their unique operational needs and scale to choose the best approach.

Identifying Strategic Requirements in Supply

Strategic requirements can be identified through factors such as:
- Impact on Competitive Advantage: If a requirement significantly affects the organization's competitive positioning, it is strategic (Ritzman et al., 2004).
- Total Cost of Ownership (TCO): Evaluating not just the purchase price but also the long-term costs can help identify strategic acquisitions (Wade, 2003).
- Supplier Risk Management: High-risk and high-impact suppliers should be considered strategic due to the potential disruption they could cause if mishandled.

Determining Environmental Impact

To assess the environmental impact of a specific acquisition, supply professionals can:
1. Utilize Lifecycle Assessment (LCA): This involves analyzing the environmental aspects of a product throughout its lifecycle from raw material extraction to disposal (Askin & Goldberg, 2001).
2. Engage in Supplier Sustainability Audits: Conducting assessments of suppliers’ environmental practices ensures alignment with organizational sustainability goals (Ellram et al., 2004).

Conclusion

Effective supply management of MRO requirements encompasses various methods, strategies for acquisitions, brand considerations, specification types, and environmental assessments. Each element plays a critical role in ensuring operational efficiency and long-term sustainability. By employing strategic approaches, supply professionals can better prepare their organizations for future challenges.
