REQUIREMENTS ENGINEERING

Not all software solutions are created equal. Give yours the advantage of thoroughly handled requirements right from the outset.

REQUIREMENTS ENGINEERING PROCESS AT IFLEXION

Business analysts at Iflexion collaborate closely with customer representatives, eliciting and validating requirements through interviews, user interface design walkthroughs, or prototype evaluations. The requirements development process within our company embraces the following stages:

Scope Definition

  • Understanding the business vision, goals and objectives of the new or replaced solution;
  • Defining the context for the project undertaking.

Analysis

  • Analyzing the elicited solution ideas, business, user, functionality and data requirements
  • Analyzing constraints, business rules, and solution quality attributes
  • Prototyping interfaces to provide visual models of the proposed solutions.

Validation

  • Prototyping requirements;
  • Testing requirements;
  • Negotiating, validating and verifying requirements with all stakeholders

Elicitation

  • Identifying requirements stakeholders
  • Eliciting requirements through interviews, workshops, focus groups, observations, document analysis, etc.

Documentation

  • Structuring and categorizing the requirements;
  • Ensuring every individual business, user, functional, and nonfunctional requirement is complete, correct, feasible, concise, prioritized, unambiguous and verifiable.

Management

  • Managing requirements version control, change control, requirements status tracking and tracing;
  • Enabling requirements reuse and risk management.

DELIVERABLES

Requirements Specifications

  • Business analyst
  • Project manager
  • QA engineer

The complete, concise, consistent and modifiable documentation (vision and scope document, SRS, use cases, etc.) delivered by Iflexion provide our Customers with a reliable basis for subsequent project planning, design, and coding.

The delivered specifications describe as completely as necessary the system’s required functionality and behaviors under various conditions, desired system qualities such as performance, usability, and security, as well as design and implementation constraints.

Technical Design

  • Business analyst
  • Project manager
  • Software architect
  • QA engineer

We propose a well-considered, feasible and sound architectural approach to the system’s technical requirements while assuring the required system availability, efficiency, performance, scalability and reliability. We carefully analyze all functional requirements to spot those that are technically infeasible or overly expensive to implement, propose the most suited underlying technology stack and come up with well-considered system architecture.

UI/UX Mockups

  • Business analyst
  • Project manager
  • UI/UX expert
  • QA engineer

Demonstration of requirements feasibility through working user interface designs allows for exploring different user interaction techniques and optimizing system usability.

The UI mockups and interactive wireframes delivered by Iflexion describe screen layouts (colors, layout, graphics, controls) and the navigation structure, including a detailed description of screen elements, their properties and behaviors under different conditions.

Working Prototype/ Proof-of-concept

  • Business analyst
  • Project manager
  • Software architect
  • UI/UX expert
  • Software engineer
  • QA engineer

We create functional prototypes and proof-of-concepts to сlarify, complete, validate, and assess the accuracy and quality of the elicited requirements.

Evolutionary prototypes are constructed by using production tools in a production-like operating environment to be subsequently elaborated into fully-functional products through a series of iterations, while securing timely course adjustments early in the project.

Flexible Engagement

We approach however fragmentary business requirements and develop them into complete, well-structured, documented deliverables.

Accurate Implementation

We tackle detailed requirements specifications presented by the Customer, efficiently translating software requirements into high-quality working solutions.

Agile Approach

We handle requirements in an inherently agile manner, supporting incremental delivery of potentially shippable portions of functionality.

Scope Creep Management

Acknowledging that, with software requirements, change happens, we ensure proactive management of ongoing volatility of scope as the project advances.
