Project Phases & Project Life Cycle

By
Concept phase:
  • briefly the project, develop very high level/summary plan.
  • describes the need for the project and basic underlying concepts.
  • preliminary cost estimate.
  • the work involved is created.
  • the end of the phase, deliver a report and presentation on its finding.

Development phase:
  • Creates a more detailed project plan, a more accurate cost estimate and more thorough project work.
  • Minimizes the time and money.

Implementation phase:
  • delivers the required work and creates a definitive or very accurate cost estimate.
  • bulk of time should be spent here.

Close-out phase:
  • completed work.
  • lessons learned(provide document/report).
  • customer acceptance.

System development life cycle(SDLC)
  • A framework to describe the phases involve in developing and maintaining systems.


Popular models of a SDLC:
  • The waterfall model - well-defined, linear stages of systems development support.
  • The spiral model - developed based on experience with various refinement project of the waterfall model.
  • The incremental model - for progressive development of operational software, with release providing added capabilities.
  • The prototyping model - developing software prototypes to clarify requirements for operational software.

Importance of Project Phases & Management Reviews

  • A project must successfully pass through each project phases.
    • Organization commit more money as a project continues, a management review to evaluate.
    • Management reviews called phase exits/kill points.
    • Important for keeping projects on track and determining if they should be:
      • Continued
      • Redirected
      • Terminated.

History of the Computer

1940 In1940, Samuel Williams and Stibitz complete a calculator which can operate on complex numbers, and give it the imaginative name of the Complex Number Calculator (CNC) later we call it Model I Relay Calculator. Stibitz stunned the group by performing calculations remotely on the CNC that located in New York, he used a telephone lines to connect. This telephone can switch parts for logic: 450 relays and 10 crossbar switches. Numbers are represented in "plus 3 BCD"; that is, for each decimal digit, 0 is represented by binary 0011, 1 by 0100, and so on up to 1100 for 9; this scheme requires fewer relays than straight BCD. Rather than requiring users to come to the machine to use it, the calculator is provided with three remote keyboards, at various places in the building, in the form of teletypes. Only one can be used at a time, and the output is automatically displayed on the same one. 1941 Konrad Zuse (German Engineer) completed the Z3.Z3 is the first o

Wireless Transmission Media

By
Wireless Transmission Media - send communications signals through air or space. Used when inconvenient, impractical, or impossible to install cables. Types Wireless Transmission Media 1. Broadcast Radio – distributes radio signals through the air over long distances such as between cities, regions and countries and short distances such as within am office or home. Transfer rate = up to 54 Mbps *BluetoothTM – uses short-range radio waves to transmit data at a rate of 1 Mbps among BluetoothTM-enabled devices. To communicate between each other a small chip is embedded in the devices. BluetoothTM enabled devices include desktop PC, notebook PC, hand-held computers, Internet appliances, cellular telephones, fax machines and printers. 2. Cellular Radio – a form of broadcast radio that is used widely for mobile communications, specifically wireless modems and cellular telephones. Transfer rate = 9,600 bps to 384 Kbps *Personal Communication Sevices (PCS) is asset of technologi

Systems View of Project Management

By
Systems thinking - taking a holistic view of projects and the organization to effectively handle complex situations. Systems approach - a holistic and analytically approach to solving complex problems that includes using a systems philosophy, systems analysis, and systems management. Systems philosophy - an overall model for thinking about things as systems. Systems - sets of interacting components working within an environment to fulfill some purpose. Systems analysis - a problem-solving approach that requires defining the scope of the system to be studied, and then dividing it into its component parts for identifying and evaluating its problems, opportunities, constraints, and needs. Systems management - addressing the business, technological, and organization issues associated with making a change to a system. Project manager identify key business, technological, and organizational issues related to each project in order to identify and satisfy key stakeholder. Projec
