Some common methods and techniques used in the systems analysis phase include interviewing stakeholders to gather requirements, conducting surveys or questionnaires, holding focus groups, creating data flow diagrams, developing use cases, and prototyping to demonstrate system functionality. These methods help in understanding the current system, identifying requirements, and designing a solution that meets the needs of the users.
when there is a system investigated, the systems analyst will find more weaknesses in it

Phase II identifies the requirements for the systems. It includes systems analysis, user requirements, necessary hardware and software, and a conceptional design for the system.

To determine which phase a cell is in, we typically assess the cell's DNA content, morphology, and the activity of specific cell cycle markers, such as cyclins and CDKs. Techniques like flow cytometry or microscopy can be employed to monitor changes in these parameters and assign the cell to a specific phase of the cell cycle. Additionally, synchronization methods can help enrich a population of cells in a particular phase for more accurate analysis.
Reverse phase chromatography and normal phase chromatography are two common techniques used in separation and analysis of compounds. The key difference lies in the polarity of the stationary phase and mobile phase. In reverse phase chromatography, the stationary phase is non-polar and the mobile phase is polar, while in normal phase chromatography, the stationary phase is polar and the mobile phase is non-polar. This difference in polarity affects how compounds interact with the stationary phase, leading to differences in retention times and separation capabilities.
Yes, there is different between requirement and analysis phases. In Requirement phase requirements are gathered and in analysis phase gathered requirements are analysed.
a system development life cycle consists of analysis,design,construction,testing and implementation.When a system is to be designed it needs a proper analysis or you can say proper investigation which includes requirements,use and future scope of a system.An analysis is the starting phase for a system which will be designed.Even a successful and through systems planning analysis and design can be ruined if a poor system is constructed as this phase consist of coding & logics and if the coding and logic and coding are not correct the implementation will also effect.That is the reason a proper check should be made in construction phase that the analysed data is up to the mark.

The analysis phase involves breaking down information into smaller parts and understanding the relationships between them. In contrast, the synthesis phase involves combining different elements or ideas to create new or improved solutions to a problem. Analysis focuses on understanding the problem, while synthesis focuses on generating solutions.
SDLC is software development life cycle and system analysis & design is one of the step in the cycle. Other steps being: 1. Requirement analysis 2. System analysis & design 3. Coding 4. Testing 5. Installation & maintenance
the first phase, the second phase and the third phase.
