By integrating DFSS training with SOA, the aim for optimal design of systems can be achieved.

SOA is a systematic approach to IT systems that involves the planning, conceptualization, designing and implementation of modular business services.

The combination of DFSS and SOA is a methodology that delivers a model to enforce standards and technical requirements.

Designing Services Optimally – DIDVO

Designing for Six Sigma is primarily for the purpose of the entire redesigning of products and services from scratch.

The aim of DFSS training is to design optimally the first time. The DIDVO methodology can be an excellent tool that can be used to improve existing SOA or create a new one. The stages of DIDVO involve systematically building up a service structure to achieve maximum benefits.

Define: The first stage, define, involves defining the project scope using tools like SIPOC and the identification of process owners and stakeholders.

The identification of project objectives is a very important part of this phase as well as definition of goal to initiate the project plan. A project charter should be developed that describes project details systematically and proves as a major guideline when undertaking further steps.

The risk matrix can be used to identify the project risks. This step also involves interviewing internal and external customers to understand their requirements properly.

Innovate: Considering the service function required to deliver measurable CTQs defined in the previous stage, a conceptual design of that service is developed in this stage.

The QFD matrix can be used in this stage to prioritize the service functions. Innovative solutions can be reached by undertaking brainstorming sessions.

The Pugh matrix may also be useful to help select the design that will be best suited to provide required services efficiently.

Design: This stage involves developing a design using tools like SIPOC and tools that can help create a high level design.

It is also desirable to use the DFMEA tool to address the design risks during designing stages. Mistake-proofing the design can also be is done in this preliminary design phase, and that helps reduce the probability of errors.

A detailed design with due consideration to the infrastructural and technical requirement can then be developed. It is necessary to carry out an evaluation of the capability and robustness of the design. Other governance, like the design scorecard and control tools, can also be put into place. Test units should be built into project plan to ensure capability of system.

A cost benefit analysis can be used to confirm feasibility of the system.

Validate: Validating the system developed is important before implementation. This phase involves using prototype programs and undertaking pilot runs that use tests simulated on basis of the requirements.

The design must confirm to requirements and then a plan must be developed for full implementation. Before implementation, any changes that may be required can be made.

Operate: The last stage is operating or launching and managing the service. It involves the implementation of the new service into the organization.

It is important to hand over to process owner and to put control mechanisms in place. A monitoring system should be established so that the process performing according to set standards. A periodic assessment is necessary to ensure continuous improvement.

DFSS is the best way to build up service oriented architecture in the earliest stages of the project.
