A software requirement specification is a document that describes what the software will do and how it will be expected to perform. It also describes the functionality the product needs to fulfill all stakeholders needs.
For example business or users a typical SRS includes a purpose and overall description specific requirements. The best the best SRS document defines how the software will interact when embedded in hardware or when connected to other softwares. Good SRS document also account for real life user so now let’s review the reasons for using SRS describes how a software system should be developed it provides everyone in work with a road map for that project in software engineering states the species for all documents it sets your communication on the right track understand the product SLS documentation helps to grow your development standards It helps to cover risks on east development stage So there are five steps to create SRS a good SRS The number one is start with outline then clarify project overview then understand users and project risks detail the project requirements and get the SRS approval and final stage so let’s discuss about the SRS outlines As always it is important to make your document structured and focused This will help your outsourcing development team avoid unnecessary effort in reading projects requirements back and forth As a result it will reduce the risk of missing information across teams You should also ensure the three main parts of the SRS including introduction overall description and detail is the requirements to create a good outsourcing software document Now let’s take a look at an outline example the first thing is introduction Within introduction you can write project purpose project scope closely and reference The second is overall description where we can write user needs assumptions and dependencies And the third is detailed feature and requirements where we can write actually the functional requirements non functional requirements external interface requirements we’ll go into detail of all these one by one So let’s start with introduction In introduction we clarify the project overview Starting the SRS with a clear introduction to describe the project purpose and give readers an overview of the project Big picture the introduction should cover the following content number one is project purpose What is the project built for Answer this question to help the leaders understand the aims and objectives of the project the second is project scope What is the business goal What values does the project deliver Find the answer to these questions to make clear the project sophistication Velocity and reference Explain the terms used in the document show your references to readers to consolidate the transmitted information so the next is our description here we understand users and project risks All developing effort is to ensure that the budget is completed and meet the user expectation To achieve this success you need to pay enough attention to analyze user user needs define show software’s end user and how they use it correctly understanding the user’s needs will keep you will keep you a clear direction on how your software should be built assumptions and dependencies Think of assumptions and dependencies that might impact fulfilling the requirements outlined in your SRS and take note of external factors for example software components reused from another project This is to prepare for any upcoming challenges in the project implementation and reduce the risk of project failure so now about features and requirements where we can actually write the project requirements in detail clearly requirements can be considered as keys to the project deliverables in general and the project success in particular The more specific requirements the easier it will be for the developers to plan and implement the project requirements are various but mainly divided into functional requirements non functional requirements and external interface requirements Each type of requirement needs to be specified and differently so let’s talk about functional requirements functional requirements describe what the software will do and define how it will function to meet user expectations You should also mention the acceptance criteria for these functional requirements to determine if a function is completed and performs as expected non functional requirements Non functional requirements include usability performance software quality security and so on they can be seen as extensions that help describe how the software will perform external interface requirements external interface requirements are types of functional requirements And these interfaces include user software hardware system communication interfaces et cetera.
