Whether you design into your product the characteristics the marketplace needs and wants. Whether every instance of your product precisely conforms to your product design. Whether you provide customer support throughout the life cycle of your product. All work is a process. Every process is a transformation.
Every process has inputs and outputs.
Every process transforms inputs into outputs. An organization is a network of processes. Organizations must identify, organize, and manage this network of processes. The link or interface between each process must be clearly defined and well managed. Product quality depends on how well this network of processes works.
