Paper presents a proposal for improvement of implementation concerning one of Lean Manufacturing (LM) tools, in particular 5S method. For that purpose there was applied Failure Mode and Effects Analysis (FMEA) in simplified form. A test analysis concerning implementation of the 5S method in one of Subcarpathian companies was performed by a team consisting of workers involved in that implementation of and external experts. Results of that analysis showed that the biggest difficulties playing role in implementation of the FMEA are the ones associated with laziness of workers and shortage of understanding advisability of 5S implementation. Obtained results are aimed at improving implementation of the 5S method in the company. They might be, however, also helpful in implementation of that method in other enterprises.

The paper contains proposals of improvement concerning implementation of the 5S method. For that purpose there were used some selected techniques of manufacturing management: team work as well as the cause and effect Ishikawa diagram. The analysis of a pilot implementation was done in one of companies located in south–east Poland by a team which consisted of workers involved in that implementation and external experts. The results of analysis were used for the improvement of approach to implementation of the 5S method in the company. Presented methodology as well as obtained results can assist in implementation of the method in other companies.

One of the requirements of the process approach is to identify the methods and evaluation criteria for process measurement. Efficiency described as the ability to achieve planned results with respect to consumed resources may be a measure used for evaluation of processes. The article presents a few concepts of efficiency indicators that can be used in assessing the activities carried out within the framework of the implementation of new projects, according to standards of automotive industry. These standards are: APQP (Advanced Product Quality Planning) and its integral part, used in the final stage of validation of the product and process, known as PPAP (Production Part Approval Process). The paper proposes three concepts of indicators assessing the efficiency of the above-described process and one concept of calculating the efficiency indicator based on the Taguchis loss function.

It is a common knowledge, that quality of a manufactured product highly depends on quality of its components. This especially might be a problem, if a component comes from external supplier, whose processes are normally beyond our control. The paper addresses a procedure called PPAP (Production Part Approval Process abbreviation known from Ford, Chrysler, General Motors manuals, issued by AIAG) which has been widely used in automotive industry to assure good quality deliveries from suppliers, beginning from early stage of cooperation, before start of production. PPAP requirements are shown as a way customer and supplier agrees upon not only product quality, but also upon manufacturing process, which must meet specified standards, set by customer (e.g. documentation, records, capability, stability, confidence in measurements etc.). The paper includes authors' assessment of resources necessary for a supplier to provide in order to meet customer's PPAP requirements. Also, reasons and perspectives of PPAP development are discussed, basing on documents proving PPAP - like practices noticeable in industries having little or nothing in common with automotive industry. In conclusion, PPAP is presented as a procedure imposed on suppliers by customers, who, being well aware of weaknesses of certified Quality Management Systems with respect to management of preventive actions in supplier's manufacturing processes, needs a strong proof that a supplier effectively introduced relevant preventive actions to a manufacturing process before it starts production of goods for a customer.

One of the requirements of the process approach is to identify the methods and evaluation criteria for process measurement. The effectiveness described as the ability to execute scheduled tasks and the objectives may be the measure used to evaluate processes. The article presents a few concepts of efficiency indicators that can be used in assessing the activities carried out within the framework of the implementation of new projects, according to APQP&PPAP guidelines. This paper proposes four concepts of indicators to assess the effectiveness of the above-described process, including index based on the Taguchi loss function.

The paper presents a concept of index for measuring the quality of improvement managed by FMEA (Failure Mode and Effects Analysis). Quality assessed only by RPNs (Risk Priority Numbers) does not properly describe achieved improvement in terms of risk reduction, which can be obtained by preventive and / or detective controls. With increasing criticism of RPN based FMEA philosophy, a need for more relevant measures of quality improvement arises. The paper introduces a set of indices which can help FMEA teams / leaders, project managers, quality managers, SQA (Supplier Quality Assurance) engineers, etc. to identify at each stage of product/process development what improvement strategy has been applied - focusing on detection of problems or rather preventing their causes.

W pracy przedstawiono nową koncepcję wskaźników opisujących skuteczność doskonalenia jakości uzyskiwanej przez zastosowanie metody FMEA (Failure Mode and Effects Analysis - Analiza Rodzajów i Skutków Wad). Podstawą przyjętej koncepcji jest postulat kwestionujący jednoznaczność oceny efektów doskonalących uzyskiwanych przy użyciu wskaźnika RPN (Risk Priority Number) podstawowego dla metody FMEA. Nie uwzględnia bowiem strategii uzyskiwania zmniejszenia ryzyka, która może być nastawiona na działania prewencyjne lub kontrolne (w konstrukcji wyrobu lub projekcie procesu). Nasilająca się krytyka wskaźnika RPN jako miary ryzyka stwarza konieczność stosowania innej miary doskonalenia jakości. Przedstawiono zestaw wskaźników istotnie wspomagających analizę ryzyka wyrobu / procesu (liderzy zespołów, kierownicy projektów, kierownicy jakości, osoby odpowiedzialne za jakość dostawców) w ocenie realizowanej strategii zmniejszenia ryzyka. Zaproponowane wskaźniki pozwalają na ilościową ocenę udziału i skuteczności działań kontrolnych - wykrywających wady lub przyczyny oraz działań zapobiegawczych, eliminujących przyczyny powstawania wad, z uwzględnieniem ich następstw dla wyrobu, procesu i klienta.
