This paper examines how a manufacturing organization applies product design decision-making across the full product life cycle. It describes the company's internally defined life cycle framework — Conception, Design, Realize & Build, and Service — and explains how each phase shapes product outcomes and profitability. The paper also addresses how cross-departmental collaboration helps resolve product development challenges. Drawing on Cao and Folan (2012) and Sy and Mascle (2011), the discussion highlights the importance of front-end strategic planning, customer involvement, and quality control in bringing competitive products to market efficiently.
Design decision-making in a product-oriented organization involves generating a series of product alternatives using clearly defined criteria. The goal is to evaluate which solutions maximize value and function while minimizing costs. This approach is driven by the need to shorten product development cycles in order to get new products to market faster. Markets can be intensely competitive, and organizations are always eager to gain a competitive advantage by reaching consumers with the best possible product before rivals in the industry.
This means that front-end strategic planning is essential when design decisions are being made. Poor decisions during product development can lead to products that no one wants to buy, or that are so expensive they cannot be manufactured in sufficient quantity (Cao & Folan, 2012). Consequently, design decisions made early in the product life cycle have a direct bottom-line impact on the profitability of a product over its entire lifespan.
The primary stages a new product goes through in the marketplace are Introduction, Growth, Maturity, and Decline (Sy & Mascle, 2011). In practice, many organizations further define the product life cycle internally by categorizing it into four major processes: Conception, Design, Realize & Build, and Service. Each of these phases carries distinct responsibilities and objectives that collectively determine whether a product succeeds in the marketplace.
The first process is Conception. This phase is strongly customer-oriented and involves planning the product's major technical parameters, including concept design, customer concerns and feedback, specifications, and initial planning. The customer's voice is central at this stage, as understanding unmet needs directly shapes the direction of the product.
The Design process covers everything from the initial idea through prototype testing, pilot release, and full market launch of the new product (Cao & Folan, 2012). During this part of the life cycle, validation and simulation testing are conducted, and product designs may be re-engineered if warranted. Various versions of a product may be created following discussions with focus groups and quality control experts, whose opinions contribute heavily to final design decisions.
The Realize & Build process represents the organization's approach to manufacturing — bringing all product components together for process simulation operations, which may include casting, molding, or machining. Manufacturing must be planned, mapped out, and evaluated, and quality checks must be performed before full-scale production can begin. If all preceding product cycle processes have been successful, the product is well-positioned to perform in the market. Weaker competitors will lose ground, and company profits will increase (Sy & Mascle, 2011).
The final process in the life cycle is the Service phase, which occurs after manufacturing and full-scale market launch. It involves the management of service information that guides customers and service engineers who may repair or maintain the product. The Service phase is important because it ensures the longevity of the product and provides helpful guidance for the end of the product's life, including proper waste management and recycling information.
