What is the difference between Business Analysis and System Analysis?
Let's start by differentiating the role from the job title. Many organizations have Systems Analysts as a job title, but often the role of performing systems analysis is often assigned to employees with other job titles, like Architect, Business Analyst, Developer or, I even know a few companies where the person with the Project Manager title performs systems analysis activities.Systems Analysis RoleFor sake of making this easy to understand, let's focus only on the role, taking for granted that different organizations may create a formal Systems Analyst job title to perform all of the system analysis activities; or they may split these activities and shove them here and there with other job titles.System Analysis activities focus around the translation of the business requirements into systems requirements. Business requirements have to be analyzed and decomposed into a series of smaller requirements for different components, providing directions for the engineering team.ExampleLet's say that the business requirement is to add a new optional "Where did you hear about us?" drop down on the Register page for a trade organization. Possible values are {"TV", "Radio", "Marc's List", "The New York Times", "The PMI Newsletter", and "Other"}This would typically be written by the Business Analyst.Systems analysis activities would decompose this requirement into:- New fields or a new table required to capture the user's selections.- A new table required to capture the drop down values.- A change in the user interface to add the drop down control.- etcetera2 Aspects of System AnalysisThe first step is to look at everything that is needed to make the new requirement work. Look at what is required in the database area, the local session information, the middleware layers, connectivity requirements, the user interface, or perhaps a new system interface, a new web service or something of the sort.After analyzing what is required, the systems analyst must look into what can break if the requirement is implemented. This implies analyzing each and every system component to ensure compatibility, and that there are no conflicts.The activities of the system analyst border those of the Business Analyst at the start of the analysis and those of the Architect towards the end of the analysis.For modern SDLC methodologies (RUP, Agile, XP, EssUP, etc.) system analysis also defines the scope of the system under consideration and models requirements by taking the black box view and whitening it. (if this is obscure, stay tuned for an upcoming blog entry on black box versus white box.)Should Analysis be performed by Analysts?I have encountered several IT Managers who believe that analysis is not necessary. My answer to them: "Whether known or not, system analysis is performed somewhere in the organization. The question is... Is it done by the Analyst, the Architect, the Developer, or if not done before deployment, then, done after deployment when the defects are analyzed? It is, by far, less costly to have the Analyst perform system analysis."
Define a compiler in IT?
A compiler in information technology is a specialized program that translates source code written in a high-level programming language into machine code or intermediate code that a computer's processor can understand and execute. This process typically involves several stages, including lexical analysis, syntax analysis, semantic analysis, optimization, and code generation. Compilers enable developers to write in more human-readable languages while ensuring efficient execution on hardware. They play a crucial role in software development, enhancing portability and performance.
Ter block diagram and describe each part of the diagram stating its purpose?
A Ter block diagram typically represents a system architecture or process flow in telecommunications or data transmission. The main components usually include the Transmitter, which converts data into signals for transmission; the Transmission Medium, which carries the signals; and the Receiver, which decodes the signals back into data. Additional elements may include amplifiers for signal enhancement and noise filters to reduce interference, ensuring effective communication. Each part plays a crucial role in maintaining signal integrity and facilitating reliable data transfer.
How is power requirement in an optical system calculated?
The power requirement in an optical system is typically calculated by considering the optical efficiency, the input light intensity, and the desired output performance. The total power needed can be derived by evaluating the losses due to absorption, reflection, and scattering in the system components. Additionally, factors such as the gain of amplifiers and the required signal-to-noise ratio play a crucial role in determining the necessary power levels. This calculation ensures optimal performance while minimizing energy consumption.
What does TSR stands for?
TSR can stand for various things depending on the context, but it commonly refers to "Total Shareholder Return," which measures the performance of a company's stock, including dividends and capital gains, over a specific period. It can also refer to "Tabletop Role-Playing Game" in gaming contexts, or "Technical Service Request" in IT and support scenarios. Always consider the context to determine the appropriate meaning.

What are role analysis techniques and how it is done?
Role analysis techniques are methods used to examine the responsibilities, tasks, and interactions associated with a particular role within an organization. This analysis involves identifying the key components of the role, understanding how it fits within the larger organizational structure, and determining the skills and competencies required to perform the role effectively. Techniques such as job shadowing, interviews, surveys, and workflow analysis can be used to gather information for role analysis.
Is QA quality assurance or quality analyst?
In general terms QA means Quality Assurance. The QA team in a software company plays significant role right from the Requirement Definition stage. The QA gets involved in approving the Requirement, Test documents, Design documents, Code review, and Test analysis.

What is role analysis?
Role analysis involves the following steps: 1. The objective of a department and functions to be identified 2. The person will be asked to state his understanding of the role 3. The other role partners to be asked to clarify the expectation from the post. 4. Then the role will be clarified to the person. The role willl be a integration of diverse viewpoints expressed by various role partners. Role analysis provides greater clarity in roles. The role incumbent knows what is supposed to do on the job, keeping the perceptions of others about his job in mind. role clarity in turn leads to improved performance in the job.
