Research activity-Project Management


  • Explain project management
It is an application of knowledge,skills,tools and techniques to project activities in order to meet stakeholder needs and expectations from a project.

  • Identify the key stages of project management
1)Initiate
In this first phase, you'll develop a project overview, map out your project management approach, and pick a project manager. The latter, in turn, will select a team and start the planning process. You'll create a project charter at this stage.



2)Plan

In the second phase, you (the project manager) will develop a roadmap for the project team. You'll set goals, define the scope, create a work breakdown schedule (WBS), identify milestones, and develop communication and risk management plans.



3)Execute

This phase involves developing a team and assigning tasks, holding meetings, and setting up tracking systems. Much of the actual work of the project happens in this phase.



4)Control

This phase happens alongside the Execution phase and involves monitoring the team performance and managing its output quality. You'll track deliverables, project costs, and the performance of individual team members and the project as a whole.



5)Close

In the fifth phase, deliverables are handed over to stakeholders and the project is brought to a formal close. You'll review your team's performance and recognize their effort. You'll also analyze the project for flaws and take notes to improve future performance.





  • Identify the advantages and the importance of implementing project management
Advantages:

  • Implement a standard approach to managing projects
  • Manage the project pipeline more efficiently
  • Optimize resource allocation
  • Centralize project reporting
  • Improve task management and visibility
  • Effective team collaboration



Importance:




1)Strategic Alignment

It ensures what is being delivered, is right, and will deliver real value against the business opportunity.



2)Leadership

It brings leadership and direction to projects.



3)Clear focus and objectives


It ensures there’s a proper plan for executing on strategic goals.


4)Realistic project planning 

It ensures proper expectations are set around what can be delivered, by when, and for how much.

Network Topology

Define Network topology?
It is an arrangement with which computer system or network devices are connected to each other.

Six different network topologies:

  • Point-to-point
  • Bus topology
  • Star topology
  • Ring topology
  • Mesh topology
  • Tree topology

  1. Point-to-point
Description:
When there's two devices are connected to each other.

Diagram:



Advantage:
  • Fast
  • No additional devices

Disadvantage:
  • Maximum two devices only
  • Cable breaks will affect to the whole network


          2.Bus topology

Description:
All devices share in one cable

Diagram:

Advantage:
  • Easy to implement
  • Less cable
Disadvantage:
  • Slow connection since other computers are connect in one cable
  • Others cannot connect when the cable is broken
 
        3.Star topology
Description:
All devices are connected to one hub or switch.

Diagram:


Advantage:
  • Easy to manage
  • Easy to detect faults
Disadvantage:
  • Expensive
  • More cable
     
       4.Ring topology
Description:
It past to one by one until it receive the information.

Diagram:
Advantage:
  • Fast sending message
  • If another host not working,can use another host
Disadvantage:
  • Take time to wait 
  • Its not privacy since others can read the message
   
       5.Mesh topology
Description:
Host is connected to one or multiple host.

Diagram:



Advantage:
  • Faster because there are more cable
  • There is many ways to send when others cable is not working
Disadvantage:
  • More cable
  • Expensive

     6.Tree topology
Description:
Known as hierarchical topology and most commonly use in the topology.

Diagram:
Advantage:
  • Fast
  • easy to identify when there's network failure
Disadvantage:
  • Expensive
