Non-functional requirements can impact system architecture. Requirements need to be precise, complete, and consistent to avoid ambiguity and conflicts during development. The operational domain of a system also imposes domain requirements that must be satisfied.
A novel defect detection method for software requirements inspections IJECEIAES
The requirements form the basis for all software products. Apparently, the requirements are imprecisely stated when scattered between development teams. Therefore, software applications released with some bugs, missing functionalities, or loosely implemented requirements. In literature, a limited number of related works have been developed as a tool for software requirements inspections. This paper presents a methodology to verify that the system design fulfilled all functional requirements. The proposed approach contains three phases: requirements collection, facts collection, and matching algorithm. The feedback results provided enable analysist and developer to make a decision about the initial application release while taking on consideration missing requirements or over-designed requirements.
Functional specifications are formal documents that describe a product's intended capabilities, appearance, and user interactions in detail for software developers. They enable expectations to be managed and streamline the development process by providing complete requirements for developers to build from without ambiguity. The functional specification analyzes user requirements, desired look and feel, customization options, and how new users will interact with the website and its business processes. Creating effective functional specifications involves fixing system boundaries, identifying stakeholders, eliciting requirements from them, analyzing gathered requirements, and managing requirements throughout the project.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Reading Summary - Software Requirements + Characteristics of Well Written Requirements
1. ************ [WIEGERS-2003], Chapter 1 **************************************************************
Many software problems arise from shortcomings in the ways that people gather, document, agree on, and modify the
product's requirements. The problem areas might include informal information gathering, implied functionality,
erroneous or uncommunicated assumptions, inadequately defined requirements, and a casual change process.
Requirements are a specification of what should be implemented. They are descriptions of how the system should
behave, or of a system property or attribute. They may be a constraint on the development process of the system
(Sommerville 1997). Requirements must be documented, they are the foundation for both the software development
and the project management activities, all stakeholders must be committed to following an effective requirements
process.
Software requirements include three distinct
levels—business requirements, user
requirements, and functional requirements.
In addition, every system has an assortment
of nonfunctional requirements.
Business requirements describe why the
organization is implementing the system—
the objectives the organization hopes to
achieve.
User requirements describe user goals or
tasks that the users must be able to perform
with the product.
Functional requirements specify the
software functionality that the developers
must build into the product to enable users
to accomplish their tasks, thereby satisfying
the business requirements. Functional
requirements are documented in a software requirements specification (SRS). System requirements describes the top-
level requirements for a product that contains multiple subsystems—that is, a system.
A feature is a set of logically related functional requirements that provides a capability to the user and enables the
satisfaction of a business objective.
Requirements specifications do NOT include design or implementation details (other than known constraints), project
planning information, or testing information. These are project requirements but not product requirements;
These sub disciplines encompass all the
activities involved with gathering, evaluating,
and documenting the requirements for a
software or software-containing product.
2. Requirements management entails
"establishing and maintaining an
agreement with the customer on the
requirements for the software
project".
It costs far more to correct a defect
that's found late in the project than
to fix it shortly after its creation.
Preventing requirements errors and
catching them early therefore has a
huge leveraging effect on reducing
rework.
When Bad Requirements Happen to Nice People
Insufficient user involvement leads to late-breaking requirements that delay project completion.

3. ************ [WIEGERS-2003], Chapter 2 **************************************************************
Customer is an individual or organization who derives either direct or indirect benefit from a product.
Signing off on the requirements document is the mark of customer approval of the requirements. Don't use sign-off as a
weapon. Use it as a project milestone, with a clear, shared understanding of the activities that lead to sign-off and its
implications for future changes
6. A Requirements Development Process
************ [WIEGERS-2003], Chapter 5 **************************************************************
Establishing the Product Vision and Project Scope
The business requirements represent the top level of abstraction in the requirements chain: they define the vision and
scope for the software system. The user requirements and software functional requirements must align with the context
and objectives that the business requirements establish. Requirements that don't help the project achieve its business
objectives shouldn't be included.
Defining the Vision through Business Requirements
7. Business Requirements and Use Cases
The business requirements determine both the set of business tasks (use cases) that the application enables (the
application breadth) and the depth or level to which each use case is implemented. If the business requirements help
you determine that a particular use case is outside the project's scope, you're making a breadth decision. The depth of
support can range from a trivial implementation to full automation with many usability aids. The business requirements
will imply which use cases demand robust, comprehensive functional implementation and which require merely
superficial implementation, at least initially.
Vision and scope document collects the business requirements
into a single document that sets the stage for the subsequent
development work.
Business Opportunity: Exploit the poor security record of a
competing product.
Business Objective: Capture a market share of 80 percent by
being recognized as the most secure product in the market
through trade journal reviews and consumer surveys.
Customer Need: A more secure product.
Feature: A new, robust security engine.
The scope description establishes the boundary and
connections between the system we are developing
and everything else in the universe. The context
diagram graphically illustrates this boundary. It
identifies terminators outside the system that
interface to it in some way, as well as data, control,
and material flows between the terminators and the
system.
The purpose of tools such as the context diagram is to
foster clear and accurate communication among the
project stakeholders.
