Case Study: White Pig ConsultingWhite Pig Consulting Ltd is a group of twenty-five consultants specialising in strategic planning, financial planning, change management and corporate governance. The group has been operating from their Nicosia offices in Ermou Street for over forty years and is a highly respected company with a long list of important clients. The company is now headed by Richard Goldbury after the recent retirement of Edward Corcoran. Under Mr.Corcoran the company operated the way it had for the last forty years: by using manual systems, a typing pool and lots of filing cabinets. Mr.Goldbury is determined to bring things up to date and has just purchased Bluetooth-enabled mobile phones for all consultants. He has engaged your company, Information Systems Implementation Services, to install a new information system. As the newly appointed Project Manager it will be your job to plan and then implement this project. Mr.Goldbury has requested that the project be complete and operational by 1st June.Project Requirements White Pig Consulting Ltd have the following information system requirements at this time: •Install a network of computers in each professional and administrative office. The network operating system should be Microsoft. •Mr. Goldbury does not know much about computers but thinks that PCs running Windows 10 Professional would be appropriate. He is keen that only ‘the best’ machines be used and has requested that you supply only IBM computers and HP printers. There are twenty- five consultants (including Mr. Goldbury) and ten assistants (each of whom will need a computer). The administrative office is to be re-organized(after most of the ten typists are retrenched) and will have a total of five administrative staff. Mr. Goldbury thinks that each of these staff should have their own computer. Each of the con-sultants (and assistants) will also need their own (small) laser printer. The administrative office will require two larger, faster laser printers with several paper trays. The building in which Paramount are housed is quite old, but provision can be made for network cables in the ceiling. There is no room suitable for a network server but Mr. Goldbury will authorize some building work to convert a storeroom for this purpose. •Install Microsoft Office XP (Professional) software on all computers. •Install broadband Internet access (via Fiber cable) and ensure all computers in the network have Internet access. •A set of Excel VBA spreadsheets macros to make up the information system that will be used by the consultants in planning their work. Mr Goldbury has detailed the requirements here and you will write these macros in Visual Basic for Applications (VBA). •Install a new accounting system using MYOB. Access to this system should be available to two administrative staff to send invoices, enter payments and print accounting reports. •Create a simple Web page advertising the company’s presence. •Most consultants often work from the premises of their clients and, although they try to take all relevant documentation with them, sometimes need additional files from the office. The system should al Tatnall & Reyes 165 low them to download these files while ‘on the road’, using Internet access via a laptop. Purchase five Bluetooth enabled laptop computers (IBM) and set up connections to the mobile phone of each con-sultant. Set up access, via the Internet, to relevant files in the office.Assignment 1b (The Project Plan)You should ensure that your project has no over-allocated resources, or dangling tasks. Before submission you should save the project with a baseline. You should include:• A letter and firm quotation to White Pig Consulting Ltd. This letter should summarise the important items in the budget and schedule, and indicate any important dates – such as when cabling work is to occur, when training is planned and when the project is to be completed. It should, however, include only information that is relevant to White Pig Consulting Ltd, and be expressed in a form that will be readily understood.• A memo to your boss, the Director, including: table of contents and executive summary, a list of any assumptions you have made, and any special requirements for the project, a detailed Gantt chart showing the critical path, with a baseline project schedule, a Network diagram (PERT chart) with no dangling tasks: that is, every task should be on a path from the first to last task, a Microsoft Project summary report, a series of other reports showing detailed costing, and resource usage.• Do you agree with the idea of Mr. Goldbury? What will you change in order to update the office?

Builders Inc. wants a program that allows its sales clerks to enter the diameter of a circle and the price of railing material per foot. The program should calculate and display the total price of the railing material. Use 3.1416 as the value of pi. First, create an IPO chart for this problem, and then desk-check the algorithm twice. For the first desk-check, use 35 feet as the diameter and $2 as the price per foot. For the second desk-check, use 15.5 and $3.50. After desk-checking the algorithm, list the input, processing, and output items in a chart similar to the one shown in Figure 3-25, and then enter the appropriate C++ declaration statementsSave your document( AS A CPP FILE) with the name material followed by your initials.Example material-rf.cpp

Description:You are asked to develop a replicator (client) that distributes a large job over a number of computers (a server group) on a single switched LAN (our Linux lab). In this assignment, a large (simulation) job can be divided into a number of small jobs, each of which can be assigned to one machine from the server group for execution. The execution results of the small jobs can be merged once all of them successfully terminate.System Architecture:client server1 server2 server3 … | | || | | |LANThe client and servers are running Network File System (NFS) so that user files are visible at $HOME directory. You may want to set up the following environment:$HOME/replicate.hosts: a list of (server) hostnames which participate in the simulation. There is no reason why your implementation cannot support up to 10 server$HOME/replicate_out: the directory that stores the small job execution result.The simulation program ” hyper_link ” (binary) is provided. In this assignment, you don’t need to know or care what “hyper_link” does, and actually it is a computing intensive (CPU demanding) simulator. The command line arguments of “hyper_link” are job# 1000000 999 1 2 2 100, where the job number determines the number of small jobs in your simulation. To allow the client to run a large job, the job# should be given in a tuple: start, end, and step. For example, the command (from the client) “hyper_link 1 100 1 1000000 999 1 2 2 100” yields 100 small jobs with the job# starting from 1 to 100. Each small job produces a screen output (see example below) at the end (if finished successfully). Your code needs to redirect the output to a file and save it in $HOME/replicate_out. For example (on the server side)

You are required to identify a problem or opportunity in the IT area and develop a solution to the problem. The project should integrate theory and application from across your educational experience and allow you to showcase your academic learning. During the course, you will identify a problem, develop requirements based on stakeholder needs, develop a design after considering alternative solutions, implement the solution (virtually is sufficient), and test the solution. Your design and test plans should take into consideration the end-user as well as the broader context of the end-user. The course culminates in a final presentation and final report.

Discuss two reasons why software systems tend to degrade over time. For each reason, identify a strategy a team could take to fight entropy.
