Concept development is the part of the product development process where you will generate, evaluate, and refine your abstract ideas, turning them into a well-defined, practical, and actionable product design ready for prototype development. As a product development company, we know extra steps taken during this phase will save time and money later on Moving forward without a well-devloped concept can be difficult and costly. In this article, we will discuss how you can develop concepts using the concept development process.
Concept development means defining and refining a specific idea or set of ideas to bring clarity, coherence, and structure. During concept development, you will take an abstract idea and turn that thought into a well-formed design using critical thinking skills, research, and analysis. By defining and clarifying your ideas, as well as exploring their pros and cons, you can come up with a feasible product concept that meets your users’ needs.
What is a product concept?
A product concept is an initial idea for a new product you want to develop, often used to secure funding for further product design services. When creating your product concept, start by defining its key features, benefits, and target market. Keep in mind that your product concept should be detailed enough to convey your idea but not so detailed that you will have trouble changing it later in development. You also want to clearly and concisely describe the product and its intended purpose, as it will be the foundation for your product development specification later.
What is the difference between a concept and an idea?
An idea is a general thought that does not have a clear definition or structure. It is a preliminary stage in the thought process that requires refinement to become a concept. On the other hand, a concept is more concrete and specific. They are well-defined and include a clear definition of what the idea is and what it entails. In short, an idea is a general thought, while a concept is developed and actionable. To convert your idea into a concept, you will need to follow the concept development process, which we outline later in this article.
Tips for developing concepts
Since we have developed hundreds of product concepts over the years, we have picked up a few tips and tricks along the way. Here are our most helpful tips for developing concepts:
- Clearly understand the problem before you begin, as it will help you focus your thoughts and help keep your ideas relevant and aligned with your goals.
- Encourage creative thinking and employ various brainstorming techniques to generate diverse ideas and concepts.
- Consider different perspectives, including everyone who will use or handle the product. Accounting for various groups’ needs and interests helps you generate well-rounded ideas.
- Gather information on consumers, market trends, and competitors, and use this information when brainstorming concepts.
- Always keep the customer in mind when conceptualizing by considering their needs, preferences, and requests.
- Collaborate with others and seek feedback on your concepts from your target demographic.
- Refine and test your ideas and make necessary changes and adjustments based on the results.
These tips for developing concepts can help you generate innovative ideas and turn those ideas into practical and successful products. But, of course, the specific techniques and approaches you use will depend on the context and the goals of your concept development effort.
Voice of the customer (VOC) research in concept development
Before generating concepts, it is important to understand what customers actually need. Voice of the Customer (VOC) research is the process of gathering feedback directly from users to identify their challenges, preferences, and expectations. Without VOC research, teams risk developing products that solve the wrong problem or include features customers do not value.
VOC research can take many forms, including interviews, surveys, focus groups, field observations, and reviews of competitor products. The goal is to uncover both stated needs and unmet needs that customers may not explicitly communicate. These insights help shape the Product Development Specification (PDS) and provide a clear direction for concept generation.
VOC research should be completed early in the development process and revisited throughout concept refinement. By grounding concepts in real customer feedback, teams can reduce risk, improve usability, and increase the likelihood of market success.
How many product concepts should you generate?
The number of concepts generated depends on the project’s complexity, timeline, and level of innovation. In many development programs, teams progressively narrow a large pool of ideas into a small number of thoroughly evaluated concepts.
| Concept Development Stage | Typical Output | Purpose |
|---|---|---|
| Initial Ideation | 20–30 initial ideas | Generate a broad range of possible solutions before narrowing the direction. |
| Concept Refinement | 3–5 promising concepts | Develop the strongest ideas in greater detail for evaluation. |
| Final Evaluation | 2–3 finalists | Compare the most viable concepts using agreed-upon selection criteria. |
| Concept Selection | 1 selected concept | Choose the strongest concept to move into detailed design and prototype development. |
When is a concept ready for prototype development?
Knowing when to move from concept development into prototype development is an important decision. Advancing too early can result in costly redesigns, while waiting too long can delay progress and increase development costs.
In general, a concept is ready for prototype development when it meets the following criteria:
- The problem and product requirements, have been clearly defined in the PDS
- Multiple concepts, have been generated and evaluated
- Major technical risks, have been identified and addressed
- Preliminary proof-of-concept testing, has been completed
- A concept, has been selected using an objective evaluation process
- Basic CAD models or detailed sketches, have been created
- Key stakeholders agree, on the direction of the design
Once these requirements have been met, the concept is typically mature enough to move into prototype development, where the design can be physically tested, validated, and refined before production.
Concept development deliverables
The outcome of concept development is more than just an idea. By the end of the process, teams should have the documentation and supporting assets needed to move confidently into prototype development.
Common concept development deliverables include:
- Product Design Specification (PDS)
- Concept sketches, CAD models, and visualizations
- Proof-of-concept prototypes
- Concept evaluation matrices and risk assessments
- Final concept recommendations
Together, these deliverables provide the foundation for prototype development, testing, manufacturing planning, and eventual commercialization while improving communication and reducing development risk.
Weighted decision matrix
After generating and refining multiple concepts, the next step is selecting the best path forward. While teams often have initial favorites, relying solely on intuition can introduce bias into the decision-making process. A weighted decision matrix provides a structured way to evaluate concepts against the factors that matter most to the project.
Step 1: define evaluation criteria
The first step is identifying the evaluation criteria that will be used to compare concepts. These criteria should align with the Product Design Specification (PDS) and reflect the project’s priorities. Common considerations include manufacturing cost, user needs, regulatory risk, development timeline, technical feasibility, product performance, and market potential.
Step 2: assign weights
Not every requirement carries the same level of importance. Each criterion is assigned a weight based on its priority to the project.
For example:
- Critical requirements receive higher weights
- Nice-to-have features receive lower weights
- Total weighting should equal 100%
This ensures that the most important project objectives have the greatest influence on the final decision.
Step 3: score each concept
Once the evaluation criteria and weighting have been established, each concept is scored using a consistent numerical scale. While scoring systems may vary between organizations, a typical concept evaluation scale is shown below.
| Score | Rating | Interpretation |
|---|---|---|
| 1 | Poor | Does not satisfy the evaluation criterion. |
| 2 | Fair | Partially meets the requirement but has notable limitations. |
| 3 | Acceptable | Meets the minimum project requirements. |
| 4 | Good | Meets requirements with several strengths. |
| 5 | Excellent | Fully satisfies the criterion and represents the preferred solution. |
Each score is multiplied by the corresponding criterion weight to produce a weighted score, allowing concepts to be compared objectively based on the priorities established for the project.
Why it works
A weighted decision matrix provides a structured and objective approach to concept selection by evaluating each option against predefined criteria. This method helps reduce subjective decision-making, ensures concepts are compared consistently, and keeps evaluations aligned with the project’s priorities. It also documents the rationale behind each decision, making the selection process more transparent while increasing stakeholder confidence in the final concept.
| Criterion | Weight | Concept A Score | Concept B Score | Concept C Score |
|---|---|---|---|---|
| Manufacturing Cost | 25% | 4 | 3 | 5 |
| User Fit | 30% | 5 | 4 | 3 |
| Regulatory Risk | 15% | 4 | 5 | 3 |
| Development Time | 10% | 3 | 4 | 5 |
| Technical Feasibility | 20% | 5 | 4 | 3 |
| Total Weighted Score | 100% | 4.40 | 3.90 | 3.70 |
The final weighted totals indicate that Concept A is the strongest overall option, with a score of 4.40. Although Concept C performs best in manufacturing cost and development time, it scores lower in user fit and technical feasibility, which are heavily weighted criteria. Concept B demonstrates balanced performance across all categories but does not achieve the highest score in any of the most important areas. By combining criterion importance with concept performance, the weighted decision matrix provides a clear and defensible rationale for selecting Concept A as the preferred design solution. This approach improves transparency in the decision-making process and ensures that the chosen concept aligns with the project’s strategic priorities and technical requirements.
What is the concept development process?
1. Define the problem
The first step in the concept development process is to define the problem your product will solve. The answer to that question will be your design’s governing theme and start your product development specification (PDS). The PDS is a written document that provides a framework for brainstorming viable concepts as it lists what you would like it to do and how you would like the user to interface with it. Additionally, the PDS will be referred to extensively throughout the product development process as you check whether your product meets the outlined requirements and solves the defined problem.
2. Generate concepts
Concept generation is the stage of product development where teams explore a wide range of potential solutions before narrowing them into the most promising concepts. Rather than searching for the perfect idea immediately, the goal is to encourage creativity, challenge assumptions, and generate multiple approaches that can later be refined and evaluated. Successful concept generation typically begins with a clearly defined objective while allowing enough flexibility for new ideas to emerge.
Teams may use a variety of concept generation techniques depending on the project, including:
- Brainstorming: Encourages open idea sharing and builds upon the contributions of others.
- Mind Mapping: Visually organizes ideas to uncover relationships and new opportunities.
- Reverse Brainstorming: Identifies potential problems first to inspire practical solutions.
- Research and Benchmarking: Draws inspiration from patents, competitive products, academic research, and adjacent industries while identifying opportunities for improvement.
Once a range of concepts has been developed, the team reviews each option to determine whether it addresses the original design challenge, meets user needs, and warrants further development. This evaluation lays the foundation for objective concept selection and the next stage of product development.
3. Depict the concepts
The easiest way to draw out your concepts is through rough sketching, also referred to as a napkin sketch. These sketches can happen during your concept generation meeting. The next step takes those rough sketches and turns them into refined drawings using several industrial design techniques. Refined drawings are 2D sketches depicting how the product, or parts of the product, could look. It also points out major functional features such as the order of operations. Often these 2D sketches are used to communicate with stakeholders and raise funds.
Once you have your 2D sketches, you need to convert these to digital models. Using computer-aided design (CAD) software such as SolidWorks, Pro/Engineer, or AutoCAD, you can digitally draw your concept and create 3D models. However, CAD software requires considerable training and experience to master. Having an experienced CAD engineer work on designing your 3D models is invaluable, as tiny tweaks to the design features can save you significant time and money in later development phases. You also cannot skip CAD design and move straight into prototype development. CAD renderings and the information held within them are required by manufacturers to prototype and manufacture your product.
4. Refine the concepts
After generating a broad range of ideas, the next step is refining those concepts to identify the most promising solutions. Rather than investing time and resources into developing every idea, teams evaluate feasibility through proof of concept (POC), which demonstrates whether a concept can function as intended before full-scale development. This is often accomplished using simple breadboard prototypes that test a single function or design feature, allowing engineers to validate key assumptions, reduce development risk, and focus resources on concepts with the greatest potential.
5. Assess the concepts
By this stage, several viable concepts should have been developed and refined. The next step is to evaluate each concept against criteria that align with the Product Design Specification (PDS), assigning greater weight to the factors that are most critical to the project’s success. Common evaluation criteria include user requirements, manufacturability, cost, material availability, safety, regulatory considerations, durability, and overall design complexity. Using consistent, weighted evaluation criteria helps teams objectively compare concepts, document the rationale behind each decision, and confidently select the strongest solution for further development.
6. Select the winning concepts
Selecting the best concept requires a structured and objective evaluation of each idea against the requirements defined in the Product Design Specification (PDS). Engineers consider information gathered throughout the concept development process, including sketches, proof-of-concept prototypes, preliminary testing, and technical analysis, before comparing each concept using a weighted decision matrix. At Synectic, concepts are scored against agreed-upon evaluation criteria using a numerical rating system, allowing the team to objectively compare alternatives, document the rationale behind each decision, and identify the concept with the greatest potential for technical, commercial, and manufacturing success.
Common concept development mistakes
Even experienced teams can make mistakes during concept development. These mistakes often reduce innovation, increase development costs, and create problems that are difficult to correct later. Here are some of the most common pitfalls to avoid:
- Converging on one idea too early – Becoming attached to a single concept too soon can limit creativity and prevent better solutions from emerging. Explore multiple concepts before narrowing your options.
- Skipping Voice of the Customer (VOC) research – Without customer feedback, teams risk solving the wrong problem or overlooking important user needs. VOC research should guide concept generation and evaluation.
- Designing features instead of solving problems – Successful products address real user challenges. Focus on the problem first, then determine which features best support the solution.
- Leaving manufacturing out of concept reviews – A concept that looks great on paper may be difficult or expensive to manufacture. Involving manufacturing engineers early helps identify production challenges before development progresses.
- Treating concept generation as a one-time activity – Concept development should be an iterative process. As new information is gathered through research, testing, and feedback, concepts should be refined and improved.
Avoiding these common mistakes can help teams generate stronger concepts, reduce development risk, and increase the likelihood of creating a successful product.
Selecting the best path forward
The specific steps of concept development can vary depending on the context and the goals of your development effort for instance if you are looking for a rapid product development process, but the steps we have laid out above are a good starting place. Remember to approach the concept development process systematically, thinking critically, and relying on research and analysis. If done correctly, you will have two to three generated, vetted, and down-selected concepts ready for prototype development.
