Importance of Strategic Planning
• The managerial process to creating and executing long term goals and
strategy
• Establish mission
• Development vision
• Establish goal
• Conduct SWOT analysis
• Conduct PEST analysis

Strategic Planning Is Important Because
• It is the company’s road map to achieving competitive advantage.
• It is the company’s game plan for how to improve financial performance.
• No strategic plan puts a company at risk.
• No strategic planning = No direction.

Information Systems Projects
Planning in IS projects is a very important function. The planning
process is divided into five stages:
i) Decomposing of project into smaller tasks.
ii) Defining interdependencies among different tasks.
iii) Estimating resources required for each task.
iv) Analyzing the risk involved.
v) Scheduling project tasks.

Preliminary Investigation
A preliminary investigation refers to limited scope inquiry undertaken to
verify whether an allegation merits a full investigation.
The six step of preliminary investigation are:
1) Understand the problem of opportunity.
2) Define the project scope and constraints.
3) Perform fact fining.
4) Analysis project usability, cost , benefit and schedule data.
5) Evaluate feasibility.
6) Present result and recommendations to management.

Systems Analysis
System analysis in software engineering is the activities that comprise software
engineering as a process in the production of software. It is the software
process. This process has 4 main activities. They are:
• Software Specification.
• Software Design and Implementation.
• Software Validation.
• Software Evolution.

Fact-Finding Techniques
Facts included in any information system can be
tested based on three steps:
Data- facts used to create useful information,
Process- functions to perform the objectives
Interface- designs to interact with users.

There are seven common fact-finding
techniques
• Sampling of existing documentation, forms and databases
• Research and Site visits
• Observation of the work environment
• Questionnaires
• Interviews
• Prototyping
• Joint requirements planning
