How you describe the Input and Process and Output Model of requirements analysis and design?

The IPO model is important as it is a blueprint for any programs or applications that will be developed. Especially data driven applications that rely on data coming in from other sources.
The input process takes data (raw, unprocessed data that is) from either a file, or from user input that needs to be converted into useful information that we can use and analyze. For instance, it could be that you wish to add two numbers, and the user is providing those numbers. Say, 3 and 5; or a file that contains multiple names of students that attend DeVry and you need to find out which is attending this class.
The processing step takes the data that was entered and perform some function on it that will make it more useful to the user. So, if I entered the two numbers to add, 3 and 5, this process will perform that calculation by adding them together 3 + 5 = 8, and store the results in memory (could be a variable of some sort). Or in the case of the file with DeVry students, it would search for this course ID among the students and sort them by what ever means that was provided, maybe by last name or D number.
The output process takes the information that was processed in the previous step and put it in a readable format where we can then use that information. For instance, it could print out 3 + 5 = 8 to the monitor or display so we can act on that answer. Or it could print out a hard copy of all the students that are attending CIS115 on Mondays sorted by their last names.
Skipping a step can be detrimental because we will not be able to solve the problem we first started out with when we decide to build a program. If you don't take any data, then the program will not know what to act on or what to process. In a data driven program, it would use what ever is in memory at that time if no data is given and print out garbage data. Secondly, if you do not process the 'data, then you just wasted your time writing the program to begin with. Your output will be black of have no useful information if the data is not processed. Last, but not least, if you can't get the data that was processed, then the program is useless.

Which output from the Collect Requirements process identifies the change control process used for requirements?
Requirements traceability matrix
What is the computer communication process?
The computer communication process is commonly known as inter-process communication. This will include input, analysis, processing, storage and output of data.
What process do you need to have the following output?
The process that you need to do the following output depends on what the output is. The process you do to get one output would not be the same process you do to get a different output.
What is the difference between process outputs and outcomes?
Processes deliver OUTPUTS. In other words, what pops out of the end of a process is an output. For example in a recruitment process the output would be newly appointed staff. An OUTCOME is a level of performance, or achievement. It may be associated with the process, or the output. Outcomes imply quantification of performance. The newly appointed people may be: - capable, or incapable of performing their role (Competence vs. Requirements) - too many, or too few (Quantity) Processes deliver OUTPUTS.

What has the author Yukio Kaneko written?

What is data output?
Data output is the method by which data can be studied or manipulated as needed by a researcher. Any statistical analysis has this processed data that is ready for analysis.
System design vs system analysis?
System design and system analysis are both important stages in the development of a software system, but they focus on different aspects of the process. System analysis is the process of studying and understanding the existing system and its requirements, including its functions, inputs, outputs, and user needs. System analysts work closely with stakeholders to gather and document requirements, create use cases, and develop models of the current system. System design, on the other hand, is the process of creating a new system or modifying an existing system to meet the requirements identified during the analysis stage. System designers use the requirements gathered during the analysis stage to create a detailed design of the new or modified system, including its architecture, components, and interfaces. In summary, system analysis is focused on understanding the existing system and its requirements, while system design is focused on creating a new system or modifying an existing system to meet those requirements. Both are important stages in the development of a software system, and they often overlap and inform one another. Effective system analysis and design can lead to the development of a high-quality software system that meets the needs of its users.
