The PDSA or Plan-Do-Study-Act continuous improvment spiral is a team oriented problem solving technique. The team focus objective is to improve the input and the output of any stage. As the PDCA, the PDSA - by Edwards Deming - are very useful techniques in product/process improvement projects.
Classical approach with the main team problem solving steps IDENTIFY business or customer problem and select one using one of more of these tools: brainstorming, check sheets, PDCA, customer feedback, pareto charts, process flow. DEFINE the problem and reduce it to smaller units so as to solve them one by one using these tools: fishbone diagrams, chech sheets, VSM, systematic troubleshooting, Pareto and process flow diagrams. INVESTIGAGE the problem collecting all sort of data and facts.
The IDEA problem solving loop is similar in nature to the PDCA and DMAIC process cycles.
The process of IDEA consists of basic step-by-step questions to guide the problem solving team toward new and innovative solutions. The IDEA report is formatted so that the four steps are concisely and clearly displayed on one page.
The Six Sigma methodology has two components: the strategy and the tactic. The strategic component is the Business Process Management (BPM) and one of the tactic components is DMAIC: Define, Measure, Analyse, Improve, Control.
According to a definition given by Joseph Moses Juran on 1999, a business process is the locigal organization of people, materials, energy, equipment and information into work activities designed to produce a required end result (product or service). Efforts to improve local process components are replaced by systematic methods to understand, control and improve overall business result. These methods have evolved to address specific business objectives.
The successful development of a project largely depends on Risk analysis which helps to adopt a systematic approach in managing risks and uncertainty associated to the project. If you know the problem chances are that you’ll make sure to avoid it: this is why performing a Risk analysis is so crucial. Every project contains a certain level or magnitude of risks, therefore it is vital to keep all project stakeholders well informed about them and about what will be done in order to mitigate these risks at an acceptable level.
