1) A problem
a. Problems are undesirable situations that prevent an organization from achieving its goals. Problems can be current or anticipated.
b. Example: users of an information system may be having trouble logging into a system or getting information in a timely manner because the system has reached its capacity. In response, the company could initiate a project to enhance the current system by adding more access lines or upgrading the hardware with a faster processor, more memory, or storage space.
2) An opportunity
a. Opportunities are chances to improve the organization.
b. Example: A company might believe it could enhance sales by selling products directly to customers over the internet. The company could initiate a project to provide direct sales of products through the website.
3) A directive
a. Directives are new requirements imposed by management, government, or some external influence.
b. Example: An important customer might require that all of its vendors use a certain form of electronic data interchange (EDI) in order to do business with them. Management would then initiate a project to implement this form of EDI to maintain business with that customer.

Problem and opportunity identification
The stages of system analysis are scope definition, problem analysis, requirements analysis, logical design and decision analysis. System analysis is defined as the study of sets of a system to find ways of improving its efficiency.

How can you select the system plan in system analysis?
To determine how well a given proposed information system a) solves the problems with the current information system shown by the problem analysis b) takes advantage of the opportunities pointed out in the Scope Definition c) satisfies the system requirements from the requirements analysis phase Also, with what is currently known about the problem itself and the estimated cost of the solution, determine if the problem is worth solving.
close system are the type of system that do not interact with the environment
Systems are created to solve problems. One can think of the systems approach as an organized way of dealing with a problem. In this dynamic world, The subject System Analysis and Design, mainly deals with the software development activities.
