Assignment 2. 1998 April

Planning and decision-making are essential parts of management activities. In planning, the manager is often faced with a number of alternatives and an assessment is needed on which of the alternatives is likely to result in the greatest benefit. Software, especially in the form of spreadsheets is often used to provide a 'what if' analysis to help the decision-maker rapidly assess possible outcome.

Your task in this assignment is to consider some aspects of decision-making involving planning in any industry with which you are familiar. The following topics must be addressed and in addition a software model is to be created and used to contribute to the analysis of options addition a software model is to be created and used to contribute to the analysis of options from which a decision is to be made. This software may be any spreadsheet or similar tool.

Any decision scenario may be used, preferably one in which several variables contribute. The following issues should be addressed:

(a) Identify in specific terms what decisions need to be made. Where would the decisions fit in the information hierarchy? where is data obtained? Is it internal or external, and does this matter?

(b) Describe how the environment is modelled in software and include a printout showing the basic model before any 'what if' modelling is done.

(c) Identify several 'what if' possibilities and produce a printout of each. Analyse each outcome in terms of the value of the information obtained contributes in any to the decision-making process.

(d) If appropriate, include a sensitivity analysis to identify which variables contribute most to the outcomes. One technique is to use a number of 'what if' tests where each variable is changed by say 10% and the results noted. A variable is 'sensitive' if a small variation in value produces a large variation in outcome. Variables that are not sensitive need to change by large amounts before having a significant effect on outcome.

(e) Can any estimate be made of the validity of this model, that is, the extend to which the model represents the reality that it is intended to represent? Are all significant variables accounted for, and could there be factors which have not been included, or which cannot be included?

Assignment 3. 1998 April

Explain the main issues in the following (approx. 100-300 words each)

Q1. The three levels of the Information Hierarchy are sometimes seen as an alternate view of the organisational hierarchy chart in which both status and salary levels are implied. Are these two views really different perspectives of the same underlying reality or is the similarity of some attributes purely coincidental?

Q2. Outsoucing is seldom an all-or-nothing decision, and in theory one, some or all of the phases of the SDLC could be outsourced. What do you consider are the three major phases that outsourcing is likely to occur and what problems of security could occur at each of these. Does the DBA have a role to play in these aspects of outsourcing.

CASE STUDY : Can GE Remake Itself as a Digital Firm?

General Electric (GE) is the world’s largest diversified manufacturer. Fortune named GE: “America’s Most Admired Company” in 1998, 1999 and 2000. Jack Welch, GE’s CEO and Chairman since 1981, often cited as the most admired CEO in the United States. Headquartered in Fairfield, Connecticut, the company consists of 20 units, including Appliances, Broadcasting (NBC), Capital, Medical Systems and Transportation systems. With the acquisition of Honeywell announced in October 2000, GE became a company of $155 billion in revenue and 460,000 employees in 100 countries. Despite GE’s size and old economy businesses, Internet Week named GE its e-business company of 2000. Did GE transform itself into a digital firm?

At a January 1999 meeting of 500 top GE executives in Boca Raton, Florida, Welch announced a new initiative to turn GE into an Internet company. Earlier initiatives transformed GE and are partially responsible for its phenomenal rise in profit over the past two decades. Those initiatives were globalization of GE in the late 1980’s, “products plus service” in 1995, which placed emphasis on customer service, and Six Sigma in 1996, a quality program that mandated GE units to use feedback from customers as the center of the program.

Welch announced that the Internet “will forever change the way business is done. It will change every relationship between our businesses, between our customers, between our suppliers”. By Internet-enabling its business processes, GE could reduce overhead costs by half, saving as much as $10 billion in the first two years. Gary Reiner, GE’s corporate CIO, later explained “We are Web-enabling nearly all of the [purchasing] negotiations process, and we are targeting 100 percent of our transactions on the buy side being done electronically. On the sell side Reiner also wanted to automate as much as possible, including providing customer service and order taking.

GE had quietly been involved with the Internet years before the Boca Raton meeting, conducting more purchasing and sell­ing on the Internet than any other noncomputer manufacturer. For example, within six months after beginning to use the Internet for purchasing in mid-1996, GE Lighting had reduced its purchasing cycle from 14 to 7 days. It also reduced its supply prices by 10 to 15 percent because of open bidding on the Internet. In 1997, seven other GE units began purchasing via the Net. The company even sold the concept to others, includ­ing Boeing and 3M.

Polymerland, GE Plastic's distribution arm, began distribut­ing technical documentation over the Web in 1994. It put its product catalog on the Net in 1995 and in 1997 established a site for sales transactions. Its on-line system enables customers to search for product by name, number, or product characteristics, download product information, verify that the product meets their specifications, apply for credit, order, track the shipment, and even return merchandise. Polymerland's weekly on-line sales climbed from $10,000 in 1997 to $6 million in 2000.

Welch ordered all GE units to determine how dot.com companies could destroy their businesses, dubbing this project DYB (destroy your business). Welch explained that if these GE units didn't identify their weaknesses, others would. Once armed with these answers, managers were to change their units to prevent it from happening. Each of GE's 20 units created small cross-functional teams to execute the initiative. Welch also wanted them to move current operations to the Web and to uncover new Net-related business opportunities. The final product was to be an Internet-based business plan that a competitor could have used to take away their unit's customers, and a plan for changes to their unit to combat this threat. Reiner ordered GE units to "come back with alternative approaches that enhance value to the customer and reduce total costs."

The Internet initiative started by trying to change GE's culture at the very top.  GE's internal newsletters and many of Welch's memos became available only on-line. To give blue-collar workers access to the Net, GE installed computer kiosks on fac­tory floors. One thousand top managers and executives, includ­ing Welch (who also had to take typing lessons),were assigned young, skilled mentors to work with them three to four hours per week in order to make them comfortable with the Web. They had to be able to evaluate their competitors' Web sites and to use the Web tn-other beneficial ways. Every GE employee was given training. Welch announced in 2000, that GE would reduce administrative expenses by 30 to 50 percent (around $10 billion) within 18 months through use of the Internet.

Many projects came out of the initiative. For example GE Medical Systems, which manufactures diagnostic imaging sys­tems, such as CAT scanners and mammography equipment, identified its DYE threat as aggregators, such as WebMD, which offered unbiased information on competing products as well as selling those products. GE products on these sites looked like just another commodity. The GE unit's major response was iCenrer, a Web connection to customers' GE equipment to monitor the equipment operation at the customer site. iCenter collects data and feeds it back to each customer who can then ask questions about the operation of the equipment through the same site. GE compares a customer's operating data with the same equipment operating elsewhere to aid that customer in improving performance. In addition customers are now able to download and test upgraded software for 30 days prior to having to purchase it. The unit also began offering its equipment train­ing classes on-line, allowing clients to take them at any time. The aggregators were also auctioning off used equipment that was in demand in poorer countries. Medical Systems established its own site to auction its own used equipment, thus opening new markets (outside the United States). GE Aircraft adapted iCenter and now monitors its customers' engines while they are in flight.

GE Power Systems then developed its Turbine Optimizer, which uses the Web to monitor any GE turbine, comparing its performance (such as fuel burn rate) with other turbines of same model anywhere in the world. Their site advises operators how to improve their turbines' performance and how much money the improvements would be worth. The operator can even schedule a service call in order to make further performance Improvements.

Late in 1999 GE Transportation went live with an Internet auction system for purchasing supplies. Soon other units, including Power and Medical, adopted the system. GE later esti­mated the system would handle $5 billion in GE purchasing in 2000, and the company would do at least 50 percent of its purchasing on-line in 2001. The system lowers prices for GE because approved suppliers bid against each other to obtain GE contracts. It also results in fewer specification errors and speeds up the purchasing process. GE estimates it saves between 10 and 15 percent of purchasing costs altogether.

GE Appliances realized that appliances are traditionally sold through large and small retailers and that the Internet might destroy that model, turning appliances into commodities sold on big retail and auction sites. GE wanted to maintain the cur­rent system, keeping consumer loyalty to their GE brand (versus Maytag, Whirlpool, and Frigidaire). Appliances developed a point-of-sale system, which they placed in retail stores such as Home Depot, where customers enter their own orders: The retailer is paid a percentage of the sale. The product is shipped from GE directly to the customer. GE Appliances claims it can now take products from its factories and get them shipped any­where in the United States virtually overnight on a cost-effective basis. In 2000 Appliances reported 45 percent of its sales, total­ing $2.5 billion, took place on the Internet. It estimates 67 per­cent of its sales will be on the Internet in 2001.

The corporation and its units have issued a blizzard of press releases touting the successes of each of GE's Internet initiatives and the consequent positive effect on financial results. "In 1999, 30 percent of our orders came in via the Web," announced Marian Powell, the senior vice president for e-business at GE Capital Fleet Services. And in 2000 "we'll have over 60 percent. That's over a billion dollars in orders." CIO Reiner said, "We are not talking about incremental change. We're talking total transformation."

A January 2001 article by Mark Roberti of The Industry Standard was skeptical. Roberti commended GE for embracing the Internet so quickly. He also noted that "these endeavors are unlikely to make GE vastly more profitable.…because the company isn't using the Internet to reach new markets or create major new sources of revenue." Roberti questioned the great savings through Internet-based cost cutting that GE claimed. To cut costs by moving business processes on-line, a firm "must eliminate-or redeploy-a significant number of employees" and "GE hasn't." For example, Roberti says, 60 percent of orders to GE Capital Fleet Services are now placed on-line, but it has not reduced its call center staff. GE reports that its selling, gen­eral, and administrative expenses as a percentage of sales fell for the first nine months of 2000 from 24.3 in 1999 to 23.6, a minor drop at best. Moreover, he notes caution coming from GE executives themselves. For example, although Reiner had projected a $10 billion saving over the next 18 months in 1999, in December 2000 he revised the 2001 savings to about $1.6 billion-not an insignificant sum, but far from the gigantic sav­ings predicted. Reducing costs by having customers and employees serve themselves via the Web has proved elusive at other companies as well, such as IBM and UPS. Roberti claims that the Internet has not brought GE a significant number of new customers.

Overall, Roberti points out, "Through the third quarter of 2000, GE still hadn't demonstrated any significant improvement in its financial results that can be directly attributed to e-business." Although GE has achieved genuine progress and even leader­ship, the company could not be generating the savings manage­ment had been predicting. He speculates that the purpose of the continuous declarations of great savings may be to boost the price of GE’s stock. Perhaps, most importantly, Roberti claims that although GE’s Internet activities will give the company a boost, it will take its competitors only a few months to catch up, leaving GE without any competitive advantage.
