The model used in this study is a model of QFD (Quality Function Deployment) for the design and calculation of cost of material (material costing), where the calculation of material cost is a major focus is to get the total cost of the components of designing products that do.
Quality Function Deployment is a structured methodology that is used in the planning process and product development, which can facilitate a working team in defining the specification needs and desires of consumers, as well as systematically evaluate the capabilities of the product or service to meet the needs and desires of consumers. The main focus of QFD is to involve consumers in the product development process as early as possible. The underlying philosophy is that consumers will not be satisfied with a product even though a product that has been produced with perfect when they did not want or need. Application of QFD methodology in the product design process begins with
the establishment of product planning matrix, or often referred to as the House of Quality (HOQ).
A to F that indicate the order of filling the parts of the product planning matrix.
FIGURE 1. The House of Quality (HOQ)
Part A: Customer Needs and Benefits.
The first part of the HOQ is Customer Needs and Benefits, or often referred to as the voice of consumers (Voice of Customer). This section contains the needs and desires of consumers.
Part B: Planning Matrix
The second part of the HOQ is planning matrix. This section is where targeting / product of interest, based on the interpretation of the research data marketing team. Target setting is a combination of the company's business priorities with the priorities of consumer needs. This is an important step in the product planning.
Section C: Technical Response.
The third part of the HOQ is a technical response, often also called Substitute Quality Characteristic (SQCs). In this section there is a process of translation of customer needs (voice of customer) into the language of the developer (voice of developer). This process will seek answers to the question how (how) the consumer needs can be met. The translation is done through a brainstorming process, namely by finding ways that need to be done by the company to meet the needs of consumers. The tools used in this process include affinity diagram, fish bone diagram, and tree diagrams.
Section D: Relationship Matrix.
The fourth part of the HOQ is filling part of the matrix of relationships (relationships
matrix). By placing the desires of consumers on the left and the characteristic body
technical at the top of the HOQ, it can be systematically evaluated their relationship. His first step is to find a causal link (impact) arising o! Er respective technical characteristics to the needs of consumers.
Section E: Technical Correlations.
The fifth part of HOQ is technical correlations matrix, which is located on top and resembles a roof. This matrix is used to assist in determining the design team who experienced a bottleneck, and define the key communication among designers. In addition, this matrix also describes the relationships and dependencies among the technical characteristics of the one with the other technical characteristics. Among elements characteristic of such techniques, may influence each other, both positive (mutual support) or negative (conflicting). By looking at the direction of improvement and technical characteristics of each, then discussed and defined together with a team of developers level of relations of any technical characteristics.
Section F: Technical Matrix.
The sixth of the HOQ is technical matrix. This section contains three types of data:
1. Technical Response Priorities.
2. Technical Competitive Benchmarks.
3. Target Technical
