Intelligent Automation

QVscribe harnesses Natural Language Processing to proactively check for compliance of the best requirements analysis tactics identified by associations such as INCOSE and leading industry experts. Automated requirements analysis throughout the authoring process empowers engineering teams to build faster by identifying errors where they are matter most and cost the least to fix - in the requirements.

QVscribe is a pragmatic solution that can drive requirements quality improvement.

Authoring & Structural Conformance

Jumpstart the authoring of your requirements with fill-in-the-blank templates that are pre-configured to follow the Easy Approach to Requirements Syntax (EARS).

Whether your requirement is ubiquitous, state-driven, event-driven, an optional feature, or an unwanted behaviour – you can choose amongst a subset of patterns that structure your requirement to be simple, clear, and a dream to work with.

Quality Analysis

Your assistant for rapidly authoring requirements that are compliant with best practices and industry standards. Authoring requirements with QVscribe empowers teams with a foundation for positive & on-time project development.

Imperatives are the critical words that command that something must be done – they are essential for a requirement to be valid. QVscribe checks each requirement for missing or improper use of imperatives, helping ensure every requirement has a single correct and actionable imperative.

Optional Escape Clauses

Catch optional language that indicates a constraint "can" or "should" be implemented. Removing unintended optional language tightens implementation scope – reducing risk & increasing control.

Weak, Vague, and Subjective Words

Detect ambiguous language that introduces uncertainty and leaves room for multiple interpretations without constraints. Are there specific words you believe should never make it into a requirements document? Easily enforce clarity for you and your team by configuring the library to include problematic wording for detection.

Superfluous Infinitives

Many folks "are capable of" kicking a football 33 yards at least some of the time, but that doesn't mean they fit the requirements to do so repeatedly and reliably. QVscribe identifies the superfluous infinitives that are unnecessary verb-phrases – avoiding verification & validation issues.

Immeasurable Quantification

We all strive to author "effective" requirements that are "efficiently" written for "robust" and "powerful" products. However, a proper requirement must avoid the use of those immeasurable quantifiers to specify precisely the constraints for development & verification purposes.

Data-driven Quality Indicators

Beyond the indicators mentioned above, QVscribe's default quality analysis checks for eight quality indicators: imperatives, negative imperatives, vague wording, optional escape clauses, superfluous infinitives, cross-referencing pronouns, immeasurable quantification, and non-specific temporal words.

Quality Warnings

Some rules are made to be broken – but it's essential you know when they are. QVscribe warns you of common quality issues that may be intentional without impacting the requirement's score – giving you the flexibility to determine which requirements genuinely need attention.

Universal Quantifiers

Words or phrases that generalize a quantity or quality should be used carefully to improve the verifiability of a requirement. QVscribe flags universal quantifiers without impacting the quality score as a warning that the requirement may be unverifiable or untestable unless restated.

Passive Voice

The use of passive voice often introduces two sources of errors. First, passive verbs such as "enhanced" and "strengthened" are notoriously ambiguous. Second, passive voice often describes a constraint on implementation rather than a proper requirement. QVscribe flags passive voice to help ensure you're not describing what must be done to the system, but rather what needs to be done by the system.

Incomplete Sentences

Incomplete sentences can cause serious trouble in requirements when critical details of who must do something or what must be done is missing. QVscribe shows a warning when it detects incomplete sentences – bringing attention to the requirements that need more information.

Unit & Term Consistency

Highlighting Potentially Inconsistent Units & Terminology

Using both imperial and metric systems of units within one document has resulted in some of the most catastrophic project failures ever seen. QVscribe rapidly detects and displays units and terminology to help you verify consistency throughout all requirements. Ensuring that no terminology or units conflicts lead to delays or rework.


Did you know?

According to NASA, the cost to fix errors rises exponentially with each successive phase of the project life-cycle, resulting in up to a 1,000 cost premium for addressing requirement errors at the operations stage. JM Stecklein, Error Cost Escalation Through the Project Life Cycle, NASA, 2004

Fast, Efficient

Requirements Similarity Analysis

Eliminate Redundant and Contradictory Requirements.

Ensuring that no two requirements are redundant or contradictory used to entail significant manual effort and cross-checking. Now, QVscribe automatically analyzes each requirement against all others to assess similarity — helping you spot requirements that either need to be updated or deleted.

Enterprise & Team Configurations

Enterprise teams require the very best tools available, and with every new release, QVscribe delivers new capabilities that enhance collaboration and management throughout the requirements engineering process.

The Project Management Institute’s 2014 Pulse of the Profession found that only 47% of organizations have a formal process to validate requirements, and that 51% of At a Glance Requirement Analysis project dollars are wasted due to poor requirements.
