Introduction
As you all know by now we recently acquired the online widget retailer Widgets – R – Us. The payoff from joining with them is that it puts us into the position to become the world’s leading widget supplier, The acquisition of a retailer aspect to our already successful manufacturing company is a positive move and puts us ahead, especially after the recent bankruptcy of We Sell U Widgets thus management revolution through integration of these two ventures is no longer in doubt but a necessity.
1. Current infrastructure.
Widgets R Us or Widgets USA are both not in a technological position to handle the type of expansion we are considering undertaking. Our individual hardware and software needs as a company we are enlisting your help and advice to put us into a position to move forward. Integrating our business support systems managed by the IT department and operations support systems handled by the network team will boost the operational capacity and efficiency and thus better synchronizing of the technology backbone.
2. Network Types.
We have 3 different network types manly (Internet, intranet, extranet).
· Internet
This is the world-wide network of computers accessible to anyone who knows their Internet Protocol also called the ip address. All you need to access the Internet is your ip address and a computer. IP address is a unique set of numbers that defines the computer's location (e.g. 100.3.9.1) .The Internet is now global and can be accessed by anyone who can get access from an Internet service provider.
· Intranet
This network that is not available to the world outside of the Intranet it’s a personal network owned by the organization. The Intranet network is connected to the Internet then the Intranet will be hidden behind a firewall and thus if it allows access from the Internet it becomes an Extranet. The firewall helps in controlling access in between the Intranet and Internet and to permit access and control traffic to the Intranet and allow only the people who are members of our organization to gain access. The company mostly uses t for printing purposes to the central networked printers.
· Extranet
An Extranet is an Intranet that’s partially accessible to people authorized but outside the organizations intranet. The actual server, the computer that serves up the web pages, will reside behind a firewall that protects any intrusion. Access levels can be changed for different individuals and groups and this is done through access usernames and passwords.
3. Types of business software

93. By Rakesh Roshan Component of Business Model Questions for all Business Models Customer Value Is the firm offering its customers something distinctive or at a lower cost than its companies? Scope To which customers is the firm offering this value? What is the range of products/services offered that embody this value? Pricing How does the firm price the value? Revenue Source Where do the dollars come from? Who pays for what value and when? What are the margins in each market and what drives them? What drives value in each source? Connected activities What set of activities does the firm have to perform to offer this value and when? How connected are these activities? Implementation What organizational structure, systems, people and environment does the firm need to carry out these activities? What is the fit between them? Capabilities What are the firm’s capabilities and capabilities gaps that need to be filled? How does a firm fill these capabilities gaps? Is there something distinctive about these capabilities that allows the firm to offer the value better than other firms and that makes them difficult to imitate? What are the sources of these capabilities? Sustainability What is it about the firm that makes it difficult for other firms to imitate it? How does the firm keep making money? How does the firm sustain its competitive advantage?
102. By Rakesh Roshan End User Development In end user development, IS professionals play a consulting role, while you do your own application development. Sometimes a staff of user consultants may be available to help you and other end users with your application development efforts. This may include training in the use of application packages; selection of hardware and software ; assistance in gaining access to organization databases and of course , assistance in analysis, design and implementing the business application of IT that you read. Control What control are needed to protect against accidental loss or damage? Is there a need to control access to data used by the application? Processing What operations on the inputs are needed to produce the desired output? What software can most effectively support those operations? Storage Does the application use previously stored data? Does it create data that must be stored for future use by this or other applications? Output What information is needed by end users and in what form should the output be presented? Input What data are available, in what form?
103.
104. Evaluating Hardware, Software and Services By Rakesh Roshan Companies may use a scoring system of evaluation when there are several competing proposals for a hardware or software acquisition. They give each evaluation factor a certain number of maximum possible points. Then they assign each competing proposal points of each factor, depending on how well it meets the user’s specifications. Scoring evaluation factors for several proposals helps organize and document the evaluation process. It also spotlights the strength and weaknesses of each proposals. Large companies frequently evaluating proposed hardware and software by requiring the processing of special benchmark test programs and test data. Benchmarking simulates the processing of typical jobs on several computers and evaluates their performances. Users can then evaluate test results to determine which hardware device or software package displayed the best performance characteristics.
105. By Rakesh Roshan Hardware Evaluation Factor Performance What is its speed, capacity and throughput? Cost What is its lease or purchase price? What will be its cost of operations and maintenance? Reliability What are the risk of malfunction and its maintenance requirements? What are its error control and diagnostics features? Compatibility Is it compatible with existing hardware and software? Is it compatible with hardware and software provided by competing suppliers? Technology In what year of its product life cycle is it? Does it use a new untested technology or does it run the risk of obsolescence? Ergonomics Has it been “ human factor engineered” with the user in mind? Is it user-friendly, designed to be safe ,comfortable and easy to use? Connectivity Can it be easily connected to wide area and local area networks that use different types of network technology and bandwidths alternatives? Scalability Can it handle the processing demands of a wide range of end users, transactions, queries and other information processing requirements? Software Is system and application software available that can best use this hardware? Support Are the services required to support and maintain it available?
106. By Rakesh Roshan Software Evaluation Factors Quality Is it bug free, does it have many errors in its program code? Efficiency Is the software is well developed system of program code that does not use much CPU time, memory capacity or disk space? Flexibility Can it handle our business process easily, without major modification? Security Does it provide control procedures for errors , malfunctions and improper use? Connectivity Is it web enabled so it is easily access internet, Intranet and extranets, on its own , or by working with web browsers or other network software? Maintenance Will new features and bug fixes be easily implemented by our own software developers? Documentation Is the software well documented ? Does it include help screens and helpful software agents? Hardware Does existing hardware have the features required to best use this software? Other Factors
107. By Rakesh Roshan Evaluation Factors for IS Services Performance What has been their past performance in view of their past promises? Systems Development Are websites and other e-business developers available? What are their quality and cost? Maintenance Is equipment maintenance provided? What are its quality and cost? Conversion What systems development and installation services will they provide during the conversion period? Training Is the necessary training of personnel provided? What are its quality and cost? Backup Are similar computer facilities available nearby for emergency backup purposes? Accessibility Does the vendor provide local or regional sites that offer sales, systems development and hardware maintenance services? Business Position Is the vendor financially strong, wit good industry market prospects? Hardware Software
