DMAIC is a structured problem- solving metodiky used in process improvit projects. It stands for Define, Measure, Analyze, Improste, and Controll. This guide provides a step overview with real-emple examples and calculations to help understand each phase.

Definovat phase

Te first step implives clearly identififying the problem and setting project goals. It includes defining sucomer requirements and project scope. For exampla, a producturing company signees high defect rates in a product line and aims to reduce bey 20%.

Měřicí fáza

In this phhase, data collection is essential. Key metrics are identified, and curret process performance is measured. For instance, measuring defect rates over a month might reveal an average defect rate of 5%. Calculations can include defect per milion opportunities (DPMO) to quantify process capability.

Analyze Phase

Data analysis identifies root causes of thee problem. Techniques such as Paretro analysis or fishbone diagrams are used. For example, analysis might show that 70% of defects are caused by a specific machine malfunction. Calculations like correlation coevents can quantify conclusivons between variables.

Improvizujte phase

Solutions are developed and tested to adresás root causes. Implementing a new accessance platidule might reduce machine downtime. Thee effectiveness can be measured by comparating defect rates before and after improvizets, calculating accessage reductions.

Control Phase

Kontroly are controled to sustain improviments. This includes monitoring processes and implementing control charts. For examplee, a control chart can track defect rates over time, ensuring they stay with in acceptable limits. Calculations endipainte setting upper and lower control limits based on process data.
