Title -:The_Why_What_Who_When_and_How_of_Software_Requirements
Article summary
This article discuss about a requirement elicitation process in the context of why, what, who, when and how. First, elaborating why should be there a requirement elicitation process, secondly what sort of requirements and types need to be defined at various levels, who are the stakeholders and how to get them involved in this process, When the requirement elicitation process should happen during the Software development life cycle and Finally how to analysis, specifying , validate requirements during requirement validation process by using various techniques .
Requirements are what the customers, users and suppliers wants from a system. This needs to be identified and determined based on the available information and agreed by customer and project stakeholders. Based on this what functional requirements must be implemented to support client business needs , what can these requirements do to effectively perform client’s business functions must be determined. Further what those non functional requirements can do to add any value to clients must be determined, since non functional requirements improve the overall user experience ,Moreover what are the limitations in implementing the requirements must be identified by the technical team based on technical limitations, less Return of Investment(ROI) due to changing trends etc.
Business requirements are typically stated in terms of the objectives of the customer or organization requesting the development of the software. User requirements look at the functionality of the software product from the perspectives of the various users of that product. They define what the software has to do in...

Moreover I found his approach of baseline business requirement first then take that as an input and finalize user requirements and then take that as an input again and finalize non functional requirements is somewhat impractical situation. As per “Software Requirements Memory Jogger” ,(Gottesdiener, 2005), these are parallel activities and it would be more effective if feedback from each of these areas is taken to determine and baseline the requirements rather than considering each as a dependency to complete the other process.
Moreover there were no requirement validation techniques mentioned in the article. Since verification of requirement is absolutely required , this aspect should have addressed further in this article.

From Ruhling's point of views, the applicable of a requirements contract are both legal and mutually satisfactory, as long as performance is met and buyer's requirements exist, it gives certain protection against price increases, and the possibility of a market predictable.
It will identify the identified constraints and assumptions of the infrastructure expansion and data warehouse build and design. As with any project it will identify the risks. The Scope of the project will be documented in the business requirements document and all other projects that are associated with this project will be documented.
Basically the work breakdown structure is something that is put together which defines the scope something that project team can understand. On the other hand, project requirement is kind of a document which tell management, what has to be produced and the exact date of completion. It also is based on responsibility factors. Requirements are the expectations which the product need to fulfill. Requirements are collected from the customer, stakeholders and Sponsor.
Another process activity useful for the prediction of changes is requirements-driven impact analysis or RIDA, for short. This analysis is used to pinpoint which software entities need to be altered in order to be able to implement a certain requirement (Lindvall, 1998). RIDA, which is conducted during the release planning phase, takes two variables into consideration. Firstly, there is the input, which refers to the existing complex system and the set of requirements. Secondly, there is the output, which represents the specific software entities that have to be changed to meet each requirement.

This phase is the main focus of the project managers and stake holders. Meetings with managers, stake holders and users are held in order to determine the requirements like; Who is going to use the system? How will they use the system? What data should be input into the system? What data should be output by the system? These are general questions that get answered during a requirements gathering phase. After requirement gathering these requirements are analyzed for their validity and the possibility of incorporating the requirements in the system to be development is also studied.
Lastly, the following three resources will be of great help in understanding this topic and executing the project requirements effectively.
A software development methodology is a standard proven process which helps programmers, architects, system analysts and others to make a well controlled and an efficient progress in the high quality software development.
The objective of this research is to help a company or an entrepreneur understand the business environment better as well as customers’ needs and, therefore, make better business decisions.
This article is the results of research on StakeRare, Stakeholder- and Recommender- assisted method for requirements elicitation, a method that is used to identify and prioritize requirements for requirements elicitation using social networks and cooperative filtering. The article states that by using social networks and cooperative filtering three common problems large-scale requirements engineering can be alleviated. These problems are information overload, poor stakeholder input, and predisposed prioritization of requirements. Information overload is unavoidable in large projects as there can be many stakeholders and requirements. Poor stakeholder input due to not recognizing, or allowing enough time to stakeholder. Biased prioritization of requirements happens due to lack of system-wide perspective due to the size of the project. StakeRare uses social media to combat these issues by using collaborative filtering to gather knowledge from relevant requirements according to stakeholders, having stakeholders identify other stakeholders, and then uses stakeholders’ input to rate the requirements. The article evaluates the performance on StakeRare by testing the process on a large scale project the comparing the results in comparison to other elicitation methods.
Timmreck (2003) states that a needs assessment is used to, “Ascertain what resources, services, equipment, or other available items exist for use in the program being planned” (p.90). The administrator has to know what resources are available for use before designing the project and the needs assessment helps gather the information about the resources that are available for that project. Timmreck (2003) states that needs assessments are also used to “Survey, assess, evaluate and do research on what services or program exist and which services are missing” (p. 90). After the information becomes available to the administrator s/he can design the project effectively because now h/she know what service is needed and what resources are available to utilize. This information that the needs assessment provides is imperative to a project’s success and therefore makes the needs assessment an integral part of the planning process.
A documentation framework is essential for any large project; hence, RUP describes how to document functionality, constraints, design decisions and business requirements. Use Cases and Scenarios, are examples of artifacts prescribed by the process and have been found to be very effective at both capturing functional requirements and providing coherent threads throughout the development and deployment of the system.
The feasibility study of a business’s design comprises of all strengths and weaknesses analyses within a particular business in order to determine whether the design is practicable and potential to benefit that business in a foreseeable future (Trimi, Berbegal-Mirabent 2012). To access this study, the researcher need to have a comprehensive understanding of the business’s resources and their interconnections which are included in the business model Canvas (Stephen, Richard 2014). This model is considered the most effective methodology in the process of supporting innovation and making decisions, thus, to assure the successfulness of a business or a project (Hanshaw 2015). This essay will discuss some central characteristics including customer
Information required to accomplish needs analysis in response to given deficiency is statement of problem presented in specific quantitative and qualitative terms and with enough detail to justify progressing to next step. Problem statement must reflect true customer requirements
A requirements workshops are very useful because it requires planning and preparation, along with good meeting facilitation skills. The most successful requirements workshops are well planned: they include clear and deliberate opening and closing activities; they include carefully selected exercises, discussions, and activities to elicit and model the requirements; and they are facilitated with the right balance of flexibility and diligence. This guide provides tips to help you think through these important aspects of a requirements workshop. The last two steps in using requirements workshops are Conducting the workshop and Following up on the workshop tasks and requirements, to generate final deliverable. The workshop conduct checklists are used for guidance on conducting the meeting. Remember to thank your participants for sharing their time and knowledge, both as you begin and at the conclusion of the workshop. Reiterate any key findings or points captured during the meeting, and distribute a summary to all participants as a means to seek clarity and feedback on the requirements details you captured. For follow up, After the workshop, review and summarize your notes with the facilitation team and send them to your workshop participants for review. Incorporate any feedback you receive into the final requirements deliverables you generate based on the workshop output. During the Workshop Be an Early Bird – Arrive at the venue early enough so that you can prepare and set up all your supporting materials. Remember Murphy’s Law.Remember that Tense Stakeholders Don’t Contribute – Your first objective should be to get everyone to relax.
