چکیده

امروزه تغییرپذیری فرآیندها مهم ترین علت افزایش هزینه و کاهش کارایی و کیفیت محصول است و شرکت ها همواره در جهت رفع آن تلاش می کنند. هدف این تحقیق، شناسایی عوامل اصلی موفقیت کاهش تغییرپذیری فرآیندها با رویکرد شش سیگما در صنعت لبنیات است. جامعه آماری این پژوهش شرکت های لبنیاتی است که مدیران و کارشناسان واحد تولید و کنترل کیفیت این شرکت ها به عنوان واحد تحلیل آماری انتخاب شدند. در ابتدا، مؤلفه های مؤثر بر کاهش تغییرپذیری فرآیندها از طریق بررسی عمیق تحقیقات گذشته تعیین شدند و سپس با استفاده از تکنیک تحلیل عاملی اکتشافی عوامل اصلی موفقیت کاهش تغییرپذیری فرایندها با رویکرد شش سیگما شناسایی شدند. در نهایت، با استفاده از آزمون بارتلت برابری واریانس عوامل اصلی موفقیت شناسایی شده مورد آزمون قرار گرفت. نتایج حاصله نشان داد که هشت عامل اصلی موفقیت کاهش تغییرپذیری فرآیندها با رویکرد شش سیگما در صنعت لبنیاتی شناسایی شدند که عبارتند از: «مدیریت تغییرپذیری فرآیندها»، «ماهیت تیم پروژه»، «ماهیت پروژه»، «مشارکت و تعهد مدیریت ارشد»، «ارتباط با مشتریان و تأمین کنندگان»، «تغییر فرهنگی»، «یادگیری کارکنان»، «مدیریت داده ها و اطلاعات». هم چنین نتایج تحقیق نشان داد که تأثیر هریک از عوامل اصلی موفقیت بر کاهش تغییرپذیری فرآیندها متفاوت است. نتیجه این تحقیق می تواند توسط تصمیم گیرندگان و مدیران شرکت های تولیدی به منظور بهبود فرآیندها و ارتقای بهره وری مورد استفاده قرار گیرد.

چکیده [English]

Nowadays, the variability of processes is the most important reason for increasing costs and reducing efficiency and product quality, and companies are always trying to remove it. The purpose of this research is to identify Critical Success Factors (CSFs) of reducing the variability of processes with Six Sigma approach in the dairy industry. The statistical population of this research is dairy companies that managers and experts of production and quality control units of these companies as the statistical analysis unit were selected. Initially, through an in-depth review of past studies, the effective components on reducing the variability of processes were determined and then using exploratory factor analysis technique, the CSFs of reducing the variability of processes with Six Sigma approach were identified. Finally, using Bartlett's test, equality of variance was tested for the identified CSFs. The obtained results showed that eight CSFs of reducing variability of processes with Six Sigma approach were identified in dairy industry, which include: "Managing variability of processes", "nature of project team", "nature of project", "engagement and commitment of senior management" "communication with Customers and Suppliers," "Cultural Change," "Employee Learning," "Data and Information Management." Also, the research results showed that the effect of each of the CSFs on the reduction of processes variability is different. The result of this research can be used by decision-makers and managers of manufacturing companies to improve processes and productivity.
