Functional Requirements Documentation
Translate supplied business and technical information into organized descriptions of required system or product functions.
Lamtas Technical Writing
Functional Specifications
Clear functional specifications describing what a system, product, application, process, or technical solution must do.
Lamtas transforms business needs, user expectations, technical requirements, and supplied source information into structured functional documentation.
Functional Specifications
Professional Functional Specification Writing & Documentation
A functional specification describes the functions, behaviours, interactions, workflows, inputs, outputs, rules, and capabilities that a system, product, application, service, or process is expected to provide.
Lamtas can develop functional specifications from business requirements, technical notes, user needs, process information, existing documentation, product information, or other appropriate source materials.
The document can provide a shared reference for business stakeholders, analysts, designers, developers, engineers, testers, project managers, suppliers, and other parties involved in delivering or evaluating a solution.
Existing functional documentation can also be reviewed and improved where requirements have changed, the original document has become difficult to use, or stakeholders need clearer and more consistent functional descriptions.
The level of detail depends on the nature of the project, available information, intended audience, required deliverable, and agreed scope of work.
What We Can Provide
Functional Specification Services
Lamtas can support the creation and improvement of functional documentation across software, technology, business processes, products, systems, and other technical applications.
Software Functional Specifications
Document application functions, user interactions, workflows, validation rules, system responses, integrations, and expected behaviour.
System Function Documentation
Describe the functions and interactions of complex systems, subsystems, components, users, external services, and operational processes.
Business Process Specifications
Document process activities, decision points, roles, inputs, outputs, business rules, dependencies, and expected results.
Functional Specification Review
Assess existing functional documentation for clarity, consistency, completeness, logical organization, terminology, and requirement coverage.
Functional Documentation Updates
Update functional specifications when features, workflows, interfaces, processes, business rules, or system behaviour change.
Our Process
How Lamtas Develops Functional Specifications
1. Understand the Intended Function
Establish what the product, system, application, service, or process is intended to accomplish and identify the principal users and stakeholders.
2. Examine Available Information
Review requirements, business processes, existing specifications, user information, technical documents, diagrams, notes, and other relevant source material.
3. Organize Functional Requirements
Group functions, workflows, rules, interactions, inputs, outputs, exceptions, and dependencies into a logical documentation structure.
4. Prepare the Specification
Draft new functional content or rewrite supplied material into clear, consistent, and appropriately detailed documentation.
5. Check Consistency
Review terminology, requirement relationships, workflows, references, numbering, completeness, and internal consistency.
6. Finalize the Document
Incorporate agreed revisions and prepare the functional specification in the required format for its intended use.

Functional Specification FAQs
What is a functional specification?
A functional specification describes what a system, product, application, service, or process is expected to do, including relevant functions, behaviours, workflows, inputs, outputs, rules, interactions, and expected results.
What is the difference between functional requirements and technical requirements?
Functional requirements generally describe required functions or behaviours, while technical requirements may describe technical characteristics, constraints, architecture, interfaces, performance, infrastructure, or implementation considerations.
Can Lamtas write a functional specification for software?
Yes. Depending on the project, software functional documentation can cover features, workflows, user interactions, system responses, validation, business rules, integrations, exceptions, and acceptance requirements.
Can an existing functional specification be rewritten?
Yes. Existing documentation can be reviewed, reorganized, edited, rewritten, updated, or formatted based on the agreed scope and available source information.
Who uses functional specifications?
Functional specifications can be useful to business stakeholders, product teams, analysts, designers, developers, engineers, testers, project managers, contractors, suppliers, and other project participants.
How is functional specification pricing determined?
Pricing depends on the document's complexity, scope, length, source materials, research requirements, review depth, formatting, turnaround time, and number of documents required. Contact Lamtas for a customized quotation.
