Part 3 : Information Gathering

Learning objectives :

Recognize the value of unobtrusive methods for information gathering.
Understand the concept of sampling for human information requirements analysis.
Construct useful samples of people, documents, and events for determining human information requirements.
Create an analyst’s playscript to observe decision-maker activities.
Apply the STROBE technique to observe and interpret the decision-maker’s environment.

Unobtrusive methods :

Insufficient when used alone
Multiple methods approach
Used in conjunction with interactive methods

Sampling :

A process of systematically selecting representative elements of a population
Involves two key decisions:

What to examine
Which people to consider

Part 2 : Fundamentals of Project Management

Learning Objective:
- Understand how projects are initiated and selected.
- Define a business problem and determine the feasibility of a proposed project.
- Plan a project by identifying activities and scheduling them.
- Understand how an alternative approach called agile development balances objectives to manage the analysis and design process.
- Manage team members and analysis and design activities so the project objectives are met while the project remains on schedule.

Major Topics;
- Project Initiation
= Problems in the organization; Problems that lend themselves to systems solutions
= Opportunities for improvement; Caused through upgrading, altering, or installing new systems

- Determining feasibility
- Defining objectives of Project
- 3 Key Elements of Feasibility:
i) Operational feasibility
ii) Technical feasibility
iii) Economical feasibility

- Determining resources
- Cost / Benefits Analysis
= The analysis to compare costs and benefits to see whether investing in the development of a new system will be beneficial.
= There are tangible benefits and intangible benefits.
= There are two main costs; development and production cost.
- Project Feasibility
- Activity Planning & Control
- Planning includes:
= Selecting a SA team & assign members to projects.
= Estimating time to complete each task.
= Scheduling the project.
- Control includes:
= Using feedback to monitor project.
= Comparing the plan for the project with its actual evolution.
= Taking appropriate action to expedite or reschedule activities.
= Motivate team members.
- Gantt chart, Network Diagram
- Gantt Charts
= Simple.
= Lends itself to end user communication.
= Drawn to scale.
- Network Diagrams
= Useful when activities can be done in parallel.

- PERT diagrams
- PERT is a network analysis technique used to estimate project duration when there is a high degree of uncertainty about the individual activity duration estimates.
- PERT uses probabilistic time estimates based on using optimistic, most likely, and pessimistic estimates of activity durations.

- Managing analysis and design activities
- Team management
= Assembling a team.
= Team communication strategies.
= Project productivity goals.
= Team member motivation.

- The Agile approach

Summary
Project management fundamentals;
- Project initiation.
- Determining project feasibility.
- Activity planning and control.
- Project scheduling.
- Managing systems analysis team members.

Problem definition;
- Issues of the present system.
- The objective for each issue.
- The requirements that must be included in all proposed systems.
