They take up a lot of time. You might not always have the product that can do the best work. It is limited by what you are allowed to do.

System Analysis and Design
its sucks
Analysis is detail design. Design in general is to abstract the concept at a higher level. System Design defines the system you try to build and help you to break down that system into smaller and manageable pieces to do the system analysis. You define your system as: Input, Core functions, Output (no specific for each part, this is the design). When you define Input, how to get the input data, action, etc., you may still in design mode, but from the overall point of view, you are doing the analysis.
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.

One example of a system and sub system in system analysis and design is an organization (system) with interrelated department (sub system). Another example would be a computer (system) and all of its components (subsystem).
Cost analysis is used to influence design and determine the most cost-effective way to support a system. By evaluating various design options and their associated costs, stakeholders can identify solutions that balance performance and budget constraints. This process often involves considering factors such as materials, labor, and lifecycle costs to optimize overall system efficiency. Ultimately, effective cost analysis helps ensure that the design meets functional requirements while remaining within financial limits.
In system analysis dfd is the primary step.it shows how the data flows from higher to lower level. which is very crucial to design. without this direct design can be a risky process.
