• A FEASIBILITY STUDY is an evaluation and analysis of a project or system that somebody has proposed.

• A FEASIBILITY STUDY is where you can find out what stakeholders want for the system

Define SCOPE of Work

• Scope of work is an area of work where all is listed and signed off

• The Scope of Work (SOW) is the area in an agreement where the work to be performed is described

• Scope of work is an area that details all the inputs and outputs of the system

A Scope of Work should include the following components: 

• The problem statement

  The goals of agreement

  The objectives/deliverables

  The recommended system

• The Purpose

  The goals

  The timeline

  The inputs & Outputs

• The Purpose

  The Problem statement 

  Goals of the

  Agreement 

  Objectives of the Agreement/Deliverables

  Timeline. 

What is the difference between goals and objectives?

• A goal is an achievable outcome that is generally broad and longer term while an objective is shorter term and defines MEASURABLE ACTIONS to achieve an overall goal.

• A goal is SMART and defines what step we need to take while an objective measures what you are going to learn

• A goal is something you want to do whilst an objective something you may need to do
