Understanding Value, Usability, Feasibility, and Viability in Product DevelopmentWhen developing a new product or service, success depends on more than just a good idea. Four essential pillars guide effective decision-making and long-term sustainability value, usability, feasibility, and viability. These factors ensure that a product not only meets user needs but can also be built, supported, and sustained in the real world. This topic explores each concept in depth and explains how they interact in the process of innovation.
What Is Value in Product Development?
Value refers to the benefit a product brings to its users or stakeholders. If a product does not solve a real problem or improve the user’s life in some way, it lacks value and will struggle in the market.
Key Questions to Determine Value
-
Does the product solve a meaningful problem?
-
Will users find the solution worthwhile?
-
Is the experience better than existing alternatives?
Value is often considered the foundation. Without it, usability, feasibility, and viability have little purpose.
Understanding Usability
Usability is about how easy and intuitive a product is to use. A valuable product may fail if users struggle to interact with it. Good usability ensures users can access the product’s features effectively and without frustration.
Key Aspects of Usability
-
User interface design
-
Simplicity and clarity
-
Accessibility for different user groups
-
Error prevention and recovery
A product with high usability reduces the learning curve, builds trust, and encourages continued use.
Exploring Feasibility
Feasibility examines whether the product can actually be built using existing technology, skills, and resources. Even if a concept has value and excellent usability, it won’t succeed if it cannot be developed efficiently.
Questions Around Feasibility
-
Do we have the technical capability to build it?
-
Is the project timeline realistic?
-
Are the right tools, platforms, and people available?
-
Can we maintain the product after launch?
Feasibility balances ambition with reality. It ensures that ideas are not just theoretically sound but practically achievable.
Defining Viability
Viability refers to the product’s long-term sustainability, especially from a business perspective. A product must not only be desirable and buildable it must also support or enhance the organization’s goals and generate sufficient returns.
Important Viability Factors
-
Revenue models and pricing
-
Market size and growth potential
-
Operational and maintenance costs
-
Legal and regulatory considerations
A viable product aligns with the company’s strategy and can survive in the competitive landscape. Without viability, even a technically brilliant and user-friendly product can become a financial burden.
How the Four Elements Work Together
The real strength of this model lies in how value, usability, feasibility, and viability work in harmony. All four are necessary for a product to succeed in the long run.
-
High value, poor usability Users may abandon the product out of frustration.
-
Great usability, no value A polished product that no one needs.
-
Valuable and usable, but not feasible A great idea that can’t be built.
-
Everything else but no viability A successful launch followed by financial failure.
Each pillar supports and informs the others. Product teams should consider all four from the earliest stages of ideation through to launch and beyond.
Applying the Framework in Real Projects
When starting a new project, teams often focus on what they can build rather than what they should build. This is where this framework becomes valuable.
Example 1 A Health App
-
Value Helps users manage chronic conditions more effectively.
-
Usability Simple interface with reminders, logs, and reports.
-
Feasibility Built using existing mobile app platforms.
-
Viability Subscription-based model with a growing user base.
Example 2 A Smart Home Device
-
Value Automates energy-saving routines.
-
Usability Voice controls and mobile app integration.
-
Feasibility Requires advanced hardware and AI software.
-
Viability Faces stiff competition and high production costs.
This type of analysis helps determine if an idea should move forward or be re-evaluated.
Incorporating Feedback
Feedback loops are crucial to refine each of the four components. Stakeholders, users, engineers, and business leaders offer unique perspectives. Iteration based on continuous learning ensures that
-
Value remains aligned with real user needs.
-
Usability evolves with user behavior and feedback.
-
Feasibility adapts to changing technical capabilities.
-
Viability stays connected to market dynamics.
The Role of Cross-Functional Teams
Achieving balance among the four elements requires collaboration. Teams that include designers, developers, marketers, and business strategists are better equipped to address all aspects of product success.
-
Designers focus on usability and value.
-
Developers assess and ensure feasibility.
-
Business experts monitor and refine viability.
-
User researchers validate value and usability through testing.
When these roles work together, product outcomes improve significantly.
Measuring and Evaluating Success
Key performance indicators (KPIs) help track how well a product aligns with each pillar
-
Value User satisfaction scores, retention, testimonials
-
Usability Task completion rates, error rates, time on task
-
Feasibility Delivery timelines, technical debt, system uptime
-
Viability Revenue growth, customer acquisition cost, ROI
Tracking these metrics allows for informed decision-making and course correction when needed.
Building successful products requires more than just innovation. By grounding every decision in value, usability, feasibility, and viability, teams can reduce risk and improve outcomes. These four pillars form a reliable framework for sustainable product development that benefits both users and businesses. Thoughtfully applied, they provide the structure and clarity needed to turn ideas into lasting success.
