In recent years, iterative development has been an increasingly important strategy for system developers, and has become the basis of many of today’s development methods, including USDP/RUP and ‘agile’ methods such as DSDM, Scrum and eXtreme Your answer should be justified and making reference to Holipets Pet Care information system. Programming. question. (Guide length about 800 words)

A. Explain what is meant by ‘iterative development,’ illustrating your answer by showing how it is applied in a development method of your choice.
B. Assess the usefulness and importance of iterative development, making reference to your chosen development method, and to others if you wish. It is acceptable to focus your discussion on the use of iterative development in the chosen method, or to provide a more general treatment of the question.

Scenario: Holipets Pet Care
Holipets is a small business that offers, “The complete holiday service for your cat or dog.” Customers who need to arrange care for their pets have two options: boarding or home visits. Holipets runs a boarding kennel and cattery which can currently accommodate up to 40 cats and 30 dogs. They are proud of the comfort that this accommodation offers to visiting animals. If required, they will collect and deliver your cat or dog for an extra charge. Alternatively, members of the Holipets team can visit pets in their homes while the owner is away. Typically, such visits are
made on a daily basis, but in some cases visits are twice daily or, exceptionally, more often – for example, if an animal requires frequent injections. As part of the visits, food and water can be provided, dogs taken for walks, and medications given. The visitor can also play with the animal. The exact services to be carried out are agreed with the owner in advance.

There are currently ten staff in addition to the couple that own the business; most of these work part-time, and duties are flexible, though only some of the staff – those whose reliability is most trusted, who have cars, and who are willing to do this work – make home visits and collect and deliver pets. Management tasks are generally carried out by the owners but there is a couple of senior staff who are trusted to deputise for them in all management tasks. Several of the staff can answer the phone and deal with bookings and enquiries.

At present, Holipets’ record-keeping is almost entirely manual, though a word- processing package is used to produce standard letters. However, the business is

growing and expansion of the cattery is planned in the near future. The owners now feel that a computerised system would give better support to their operations. It is expected that staff will use the new system to support and record the tasks that they carry out – receiving arrivals, taking bookings, home visits, etc.

Company operations

Bookings are taken by telephone and recorded, currently in a large diary. It is important to keep track of the number of bookings for cats and dogs that have been made on each day, as a booking can only be taken if there is a free ‘room’ in the right accommodation for the duration of the required stay. Cats are never booked into dog accommodation, and dogs are never booked into cat accommodation.

When a customer requests a kennel or cattery booking, if the booking can be taken, the member of staff records it in the diary, being sure to note the start and end dates and whether collection and delivery are required. Some customers have more than one pet. If the customer is a new one, their name and contact details are taken and recorded on an index card along with details of the pet(s): name, dog or cat, breed, age, type of food, any medical treatment, and any other notes. For repeat bookings, any of these details can be updated as necessary, including adding a new animal for
an existing customer. There may be a discussion of cost: the staff know the residential rates for dogs and cats, and can advise the customer of the cost of the stay. The person taking the booking will either print out a confirmation letter as soon as the phone call is ended, or make a brief note of the booking on the whiteboard so that the letter can be sent out later. The letter gives the customers the details of the booking, and requests a 20% deposit.

Deposits which are received by cheque, and usually in the post must be recorded and banked. The balance of the payment is made when the animal arrives or is collected and this must also be recorded. It is important that records are kept of all animals arriving and leaving. Following up unpaid deposits is done on an ad hoc basis by the owners: it would be helpful if the new system could flag these up in some way. Bookings are eventually cancelled if no deposit is received.

When home care is booked, similar details are taken, using the customer card index and another diary. There is as yet no limit on the number of visits in a day, as this side of the business is so far quite small. Also, rather than sending out a confirmation letter immediately, an appointment is made for one of the staff to visit the owner and pets at home, in order to discuss practical details such as where food is kept and what care is to be given. At present, the staff member will be given
handwritten notes of the name and address, dates, cost of visits and the required deposit. Another reason for this meeting is to confirm that it appears safe for staff to make the visits. The deposit must be paid at this appointment, and a confirmation letter detailing what is to be done on each visit (feeding, medication, walks etc.) and the outstanding balance to be paid will be sent out afterwards. The balance must be paid before the first home visit or left for staff to collect on the first visit. All payments must be recorded.

The scheduling of home visits and the collection and delivery of pets is currently rather haphazard, and last-minute rearrangements are not uncommon. The owners have requested that the new system should allow all these activities to be assigned to specific staff, using a diary that can be viewed and updated at any time, and that it will print a daily list for each person who will be carrying out any of these activities. The owners would also like the system to print a list of all arrivals, departures and pets in residence for a given day. To help them manage the business they would also like summary reports about the number of rooms booked and home visits made, each over a monthly or yearly period. It will also be necessary for the owners or someone acting for them to maintain details of staff, the capacity of the accommodation, and the rates charged for each service.
