Your organization earns $50 million in annual sales, has 500 employees, and plans to acquire 100 new portable computers. The chief financial officer has asked you to lead a project team to define users’ computer hardware needs and recommend the most cost-effective solution for meeting those needs. Who else (role, department) and how many people would you select to be a member of the team? How would you go about defining users’ needs? Do you think that only one kind of portable computer will meet everyone’s needs? Should you define multiple portable computers based on the needs of various classes of end user? What business rationale can you define to justify this expenditure of roughly $50,000?

Program Plan Intro

Components of computer:

Computer has four major components, they are:

  • Central processing unit (CPU)
  • Memory unit
  • Input devices
  • Output devices

Central Processing Unit (CPU):

  • CPU plays the key role in a computer by carrying out instructions of a computer program.
  • It performs all the basic logic, arithmetic, controlling and input/output operations that are specified by the instructions.
  • The CPU comprises of two units, Arithmetic logic unit (ALU) and control unit (CU).

Memory unit:

  • Once computer program instructions set are transformed into machine code by CPU, the machine code is stored in memory.
  • Then the CPU fetches the required data and instructions from memory, perform the required operations and then sends the result and next set of instructions back to memory.

Input devices:

  • The devices used by the user to feed information to computer, such as a hard drive, keyboard, or a networking card.
  • These devices get the data from outside world into computer in the way that human eyes and ears bring the data to brain.

Output devices:

  • Output devices are used by computer to deliver the information to the user, such as a monitor, printer, and speaker.
  • The CPU takes the machine code present in memory and converts it into a format that is required by monitor’s hardware.
  • Then the monitor’s hardware alters that information into different light intensities such that words or pictures are seen.

Explanation of Solution

People selected as team members:

  • A representative from each department is to be selected to help define unique user needs.
  • The project team may include managers in marketing, sales, human resources, accounting and finance...

Explanation of Solution

Defining user needs:

  • The user needs are to be defined based on department.
  • Each department representative takes care of respective user needs...

Explanation of Solution

Need of multiple portable computers:

  • It is better to select different portable computers based on needs of user.
  • The class of portable computers may change based on different needs of user...
