Walk By – 7 wastesSELV July 2 – July 5, 2012Walk-by / Lean Manufacturing / SPSA principle concept of Lean Manufacturing (and SPS) is that most problems are visible and the best improvement ideas will come from people going to the factory floor and observing the problems. A “Walk-by” is a special way to test our own assumptions about what is going on in the process by “seeing” the actual process running. In the SPS, this is the first part of the concept “I SEE, I DO”. More often than not, when we actually “see”, we see that something else is going on than what we expected. The regular Walk-by is, finally, to check whether progress is happening at the desired pace. Walk-by is an essential responsibility of all MBC and DVC employees.Schneider Electric - GST \ SPS – G. PARRINI – 2010 2Walk-by is an essential part of the SPS assessmentWalk-by, during an SPS assessment, is a good opportunity to have the vision of the factory floor from the eyes of a person unfamiliar to the plant. Assessors are not safety experts but each time they “walk-by” they look for safety issues. Most of the issues seen are not expert related issues but simple observations of behavior that could be seen at one moment and may not be observed later. The Schneider plant of Pisek gives the name “Ghost” to those issues highlighted during a Walk-bySchneider Electric - GST \ SPS – G. PARRINI – 20103Walk by is also an extremely effective tool for the identification of waste●During the walk-by…● We see ● We ask why? ●And most of the time the reply is: “That’s an exceptional situation, you will not see it again tomorrow” This is not an acceptable response to a “why” question!Schneider Electric - GST \ SPS – G.

7SEA管理目录什么是7SEA7SEA管理的要素什么是7SEA7SEA是由素养（Sentiment）、整理（Sort）、整顿（Straighten）、清扫（Sweep）、清洁（Sanitary）、安全（Safety）、节约（Save）、环保（Environmental protection）和活动（Activity）的英文开头字母构成的，其也是7SEA管理法的要素。
7SEA现场管理法是"5S管理"的基础上进一步完善发展起来的。
7SEA管理的要素(一) 管理要素7SEA现场管理法中的字母分别是"素养(Sentiment)"、"整理(Sort)"、"整顿(Straighten)"、"清扫(Sweep)"、"清洁(Sanitary)"、"安全(Safety)"、"节约(Save)"、"环保(Environmental protection)"和"活动(Activity)"、的英文开头字母，也是构成7SEA管理法的要素。
现场是由各生产要素构成的，现场管理是对人、机、料、法、环、信息、制度等生产要素的综合管理，而人不仅是诸多生产和管理要素的核心，更是实施各项管理的主体。
因此，只有把员工作为系统最重要的要素，去主动推动和保证系统的运行，才能在系统中的其他要素发生变化时，由人这个第一要素及时准确地进行相应的变化，推动系统的处理和反馈，使生产现场的各要素重新达到和谐统一。
没有了人，再完善的系统也将失去生命力。
而和人员的数量相比，高素质的员工是系统的决定性的要素。
因此，应把高素质的员工作为现场管理的根本，首先对"5S"的顺序进行调整，把"素养"作为7SEA的第一条，纲举目张，总领其它要素，并且对各要素的内容进行了充实和新的诠释，进一步发展和完善了"5S"管理。
