Dear Ms. Weston,

Performance of the CPT Equipment

    I’m Pleased to tell you about our experience with the CPT Word Processor as you requested recently____example____ I assume you have looked at several machines and have narrowed down your choices.

Here are my observations.

We use the equipment as dedicated word processors, although we do have the ability to link up with our computer installation.

The step-at-a-time development of our word-processing center has, we think, saved us money and training time. ____10____

Performance

In terms of performance, the CPT equipment is excellent. ____11____ Moreover our service contract and warranty have covered all maintenance costs.

We have software packages that check spelling and signal when a mistake occurs. ____12____ Using both printers, we recently prepared 1200 individually typed form letter mailings a under four hours. We have no complaint about our preparation of executive reports.

Example: I

A. So it works very well and has so many different functions.
B. Also it has reduced the confusion that exists about buying software packages.
C. The train stops at each station for only fifteen minutes.
D. We began with two work stations and now have four.
E. Our routine letters are prepared from disc-stored masters.
F. The Rotary W printer with a speed of 45 characters a second can easily handle two input stations.
G. In contrast, its size and weight are ideal for carrying.
H. We have not yet experienced mechanical problems so far.
I. We are pleased with its performance and multi-functions.

Icon Acoustics: Bypassing Tradition
Like most entrepreneurs, Dave Fokos dreams a lot. He imagines customers eagerly phoning Icon Acoustics in Billerica, Massachusetts, to order his latest, custom-made stereo peakers ____example____

Like most entrepreneurs, Dave has taken a long time to develop his dream. ____(8)____ Dave discovered that he had a strong interest in studio engineering, He took independent-study courses in this area and by graduation had designed and built a pair of marketable stereo speakers. Following graduation, Dave pursued his interest in audio engineering. He landed a job as a loudspeaker designer with Conrad-Johnson, a high-end audio-equipment manufacturer headquarters in Fairfax, Virginia ____(9)____

Dave identified a market niche that he felt other speaker firms had overlooked ____(10)____These affluent, well-educated customers are genuinely obsessed with their stereo equipment. ‘They’d rather buy a new set of speakers than eat,’ Dave observes.

    Dave faced one major problem---how to distribute Icon’s products. He had learned from experience at Conrad-Johnson that most manufacturers distribute their equipment primarily through stereo dealers. Dave did not hold a high opinion of most such dealers; he felt that they too often played hardball with manufacturers, forcing them to accept thin margins. ____(11)____This kept those firms that offered more customized products from gaining access to the market. Perhaps most disturbing, Dave felt that the established dealers often sold not what was best for customers, but whatever they had in inventory that month.

    Dave dreamed of offering high-end stereo loudspeakers directly to the audio-obsessed, bypassing the established dealer network. ____(12)____ “My vision for the future is one where all manufacturers sell their products directly to end user. In this way, even the audiophiles in Dead Horse, Alaska, can have access to all that the audio-manufacturing community has to offer.”

Example: I.
A. At the age of 28, Dave set out to turn his dreams into reality.
B. Furthermore, the dealers concentrated on only a handful of well-known producers
C. Who provided mass-produced models.
D. The firms tend to plow their money in to developing their products and have little left over to market them.
E. Within four years, Dave had designed 13 speaker models and decided to start his own company.
F. To serve the audio-addicts segment, Dave offers only the highest-quality speakers.
G. It all began while majoring in electrical engineering at Cornell.
By going directly to the customers, Dave could avoid the dealer markups and offer top-quality products and service at reasonable price.
H. This niche consisted of “audio-addicts”----people who love to listen to music and appreciate first-rate stereo equipment.
I. He sees sales climbing , cash flowing, and hundreds of happy workers
Striving to produce top-quality products that delight Icon’s customers.

 For each gap 8-12, mark one letter (A-I) on your Answer sheet.
 Do not use any letter more than once.

Career Planning
For many employees, automatic promotion up the ranks of a company is becoming increasingly rare. A new study suggests that, in response, employers need to consider how they can help staff develop their careers.
Employers need to rethink their approach to career management completely, according to the latest research by the Institute of Employment Studies. The new study finds that in fact there is little opportunity for individual career development in many large organisations. (example)____.The Institute of Employment Studies makes it clear that it is not good practice for companies to hand over career development to individual employees and then simply leave them to get on with it. (8) ____.
So how should employers help their staff develop a career? Most employees have come to accept that career development is not always the same thing as upward promotion and a higher salary. (9) ____.They must also ensure that these opportunities are extended to all their staff and not just to selected individuals.
Nick Bridges, who is Director of Human Resources Policy at the Bank of Eastern England, believes there is more talk than action in this area. (10) ____. One way, he believes, for companies to show how serious they are about individual learning is to make it an official part of company practice, as the Bank of Eastern England has done. (11)____. This document, he points out, has made the role of managers clear, and the company has also invested huge amounts of money educating managers so that they can then train their staff.
Another company, British Chemicals, has contracted an independent organisation to help staff with confidential career advice. According to John Yates, the head of Individual Learning and Development at British Chemicals, there is an important role for outside agencies to play in the career management process. He adds that it is company policy for managers to give all staff ‘roadmaps’ which show possible career routes within the company structure. (12)____. This has worked especially well, he says, for staff who are used to depending on their line managers for guidance.
Many large organisations now recognise that career development cannot be regarded in isolation, and must be part of an overall business strategy. Human Resources has a real role to play in building a strong workforce which meets a company’s long-term business needs and makes it more competitive.

A Its policy statement says that by 2006, eighty per cent of its staff will have a professional qualification.
B His recommendations go even further than that, and he has called for a national debate on the issue of what should be regarded as a career in the future.
C This change of attitude means employers need to place more emphasis on giving staff the chance to develop a range of skills through horizontal job moves.
D It points out that employees need to know what the overall company vision is in order to achieve many of these.
E The problem that often arises is that, while they are increasingly encouraged to manage their own careers, they are not provided with the knowledge and training to do this.
F They are able to see that, contrary to expectations, jobs in different fields are similar, and they can also see how it is possible to cross over to other areas.
G Its employees are no longer motivated by these factors alone, and the problem today is matching a person’s motivation with the right job.
H He argues that while Human Resources managers are saying the way forward is through self-managed learning and self-development, they are still failing to provide adequate learning resources.
I The main reasons for this, it concludes, are the recent cuts in the number of middle-management posts, and the changes that have taken place in the responsibilities of personnel departments.

Marketing
In the past, the concept of marketing emphasised sales. The producer or manufacturer made a product he wanted to sell. ____ example ____ . Basically, selling the product would be accomplished by sales promotion, which included advertising and personal selling ____ (8) ____ Distribution consisted of transportation, storage, and related services such as financing, standardisation and grading, and the related risks.

The modern marketing concept encompasses all of the activities mentioned, but it is based on a different set of principles ____ (9) ____ In other words, goods should be produced only if they can be sold. Therefore, the producer should consider who is going to buy the product ------ or what the market for the product is ---- before production begins.

Marketing now involves first deciding what the customer wants, and designing and producing a product that satisfies these wants at a profit to the company ____(11)____ This is much more difficult since it involves human behaviour. ____(12)____ Thus, demand and market forces are still an important aspect of modern marketing, but they are considered prior to the production process.

 For each gap 8-12, mark one letter A-I on your Answer Sheet.

Altered Images
We have teamed up with The Career and Workwear Show to find the best-dressed organization. Two hotel groups and a management center have made it to the shortlist.
Uniforms project an instant image about a business, as well as creating a team spirit among staff. Choose the wrong workwear and you risk upsetting your customers and employees.
Three entrants have been shortlisted in the competition to find the best-dressed business: Country Hotel Group, Goring Residential Management College and Major Hotels. (example) ----------.
A detailed entry form set out to discover the thought processes the entrants had used before they selected their new uniforms. (8) ____. In addition to price and style the judges wanted to know how the organisation introduced the new look and what lessons it had learnt.
The Country Hotel Group was looking for a uniform that was comfortable to wear and presented a relaxed country image to guests. The firm admits to placing a great emphasis on the clothing and appearance of its staff. (9) ____. A brief was issued to a number of companies who then had to present their ideas in a fashion show format to 50 employees. After the design was chosen, one hotel tried out the uniform for three months. (10) ____
The aim of the new uniform at Goring Residential Management College was to make staff instantly recognisable to course participants. The chosen design from Classy Rags established a clear corporate image at the college. There were many different outfits but only three fabrics had been used throughout the range and therefore the uniform was easily recognisable. One of the judges in the competition, fashion journalist Sally Bain, was also impressed with the value for money aspect of the uniforms. (11) ____
At Major Hotels a new uniform was needed to replace the old one which was considered to be ‘old-fashioned and unattractive.’ The new design was well received by the reception staff of the hotel chain. (12) ____. The new bottle-green uniforms were selected from Rayner Corporate Clothing. It was felt that it was a functional choice of colour and made a pleasant change from the more traditional black.
 Do not use any letter more than once.


A. Feedback was then collected from staff at the hotel and minor changes were made before the
uniform was introduced across all hotels.
B. The award will be presented to the competition winners at The Career and Workwear Show which will be held at Business Design Centre in London.
C. They all believe that its introduction has led to a modern, more professional corporate image and greater confidence among them.
D. One entry predicted that uniform fabrics would incorporate security aids which are read by sensors on doors and only allow access to authorised personnel.
E. In her opinion this had been achieved at half the cost of the other entries, with the average cost per person being £201,and each uniform being expected to last two years.
F. It asked why the uniform was introduced, who it was designed to be worn by, and how the firm went about selecting a supplier.
G. She felt that the head receptionist at the hotel should be asked to put forward the views and preferences of the team.
H. In its entry it said:‘Substantial investment has been made in this uniform because uniforms are seen as a very important area.’
I)One reason for this is that all three proved to the judges that they had thoroughly researched their choice of new uniforms.

    A modern bank provides many services other than checking accounts. ____1____
    If you went to a bank to open a savings account, you would go through almost the same procedures followed in applying for a checking account. ____2____ Then you would be given a passbook in which your initial deposit would be recorded.
