Quality Function Deployment (QFD) Vs. Requirements Analysis

Introduction

Organisations use development methods when developing a product or a service, to help them deliver the product/service efficiently and also to help them keep cost of production to a minimum. There are quite a few development methods depending on what the project is, these methods are available for companies to use to increase their productivity. The development methods I will be examining in this essay are Quality Function Deployment (QFD) and Requirements Analysis.

Quality Function Deployment is a method used in production which is aimed at meeting the needs of the customer whilst maintaining quality throughout the production phase.Requirements Analysis is a method which is used in software development to understand what the customer’s needs and expectations are from a proposed computer system.

Requirements Analysis

Requirements analysis, also called requirements engineering, is the process of determining user expectations for a new or modified product. These features, called requirements, must be quantifiable, relevant and detailed. Requirements analysis is an important aspect of project management. After user requirements are captured in the form of interviews, research, questionnaire and surveys, the requirements are analysed, modelled and are documented usually by a Requirements Analyst before the stage of designing the proposed computer system begins.

House of Quality

The House of Quality is the most popular form of QFD and is used by a multidisciplinary team to interpret the customer requirements into a product that matches stated requirements at the same time as bearing in mind the engineering objectives and competition in the market for a similar product.

The House of Quality consists of six major components

Customer Requirements is well organised lists of requirement information gathered from customer or the end user this statement is also known as “Voice of Customer” (V.O.C).  The company develops a focal point on what the customer wants rather than what they want to develop.

Technical Requirements is an organised set of relevant and measurable design characteristics of the product that is being developed to respond to customer requirements. Characteristics would be presented in an order.

Interrelationship Matrix the interrelationship matrix is used to calculate the relationship between the customer requirements and the engineering characteristics of the product. The correlation is measure by either symbols or numbers that show not only the relationship but also how strong the correlation is.

Planning Matrix the planning matrix allows a development team to compare their product against a  competitor’s product and see how well it does. They will also develop a technical evaluation of prior generation products and competitive products.

Conclusion

QFD uses the “House of Quality” model to exemplify data and ideas collected from the users/customer Requirements Analysis uses models such as Use Cases to do the same thing. Both methods, first stage is to search for the understanding of what the customer requirements are first  instead of designing the product/service first.

Conclusion

In my opinion both Quality Function Deployment and Requirements Analysis are good methods used in  project management. Despite the fact that they’re used in different company environments, both Quality Function Deployment and Requirements Analysis have similar characteristic that are used frequently in both methods, some similar characteristics they both have even sometimes perform the same functions such as establishing what the use requirements are. Both methods ensure that the final product / service meet the requirements of its intended user / customer. They are both designed to reduce labour hours to construct a product/service, costs and to guarantee a good quality outcome product to the user requirements specified .
