- 3 Mu
stands for the three points ‘Muda’ (Waste, see ‘7 types of waste’), ‘Muri’ (overload of employees and machines) and ‘Mura’ (irregularity of the processes) and refers to the employees, technology, method and time. They are considered negative and should be avoided.
- 7 types of Waste
- Overproduction (making more than currently needed)
- High stocks (final, semi-finished products, vendor parts and materials stored as stocks do not add value)
- Rework/errors (faulty products disrupt the production flow and require expensive repair)
- Area (too much occupied area is a Waste of infrastructure)
- Search/transit times (all search and transit times are wasteful)
- Waiting times (‘idle hands’ of an employee, process cycle not optimised)
- Transport times and routes (movement of materials or products does not add value)
- 7 M
These are the 7 most important factors that must be taken into account in a cause analysis such as Ishikawa diagram:
The original 5 M method was extended by two important factors:
- Management and
- 7 W
see 7 types of Waste
- 7-W questionnaire
- What – needs doing?
- Who – does it?
- Why – does he do it?
- What – method is used?
- When – will it be done?
- Where – is it being done?
- Why – won’t it be done differently?
Related to the 7-W questionnaire is the principle of ‘Go to the source’ (Genkin-butso). This says, in the case of undesirable results or errors, to ask 5 times for the ‘why?’ to achieve a solution. It also says, however, that managers should get an clear picture of the on-site situation, for example a manufacturing process, and not just decide remotely.
- Authentification as a Service
describes a service that includes managing secure and protected access to cloud-based data and applications. More and more businesses are exploiting the benefits of managing their data and applications in a cloud. The authentication of individuals, however, is a security risk when accessing from various sites and devices; this can be minimised with the help of such a service.
- Additive Manufacturing
Generally known as 3D printing, but basically refers to a method which uses physical or chemical processes to transform materials such as powders or liquids into 3D models, prototypes or even end products. This method – also called rapid prototyping – does not require any tools or casting moulds, unlike standard manufacturing shaping processes. Its use is particularly worthwhile for components with geometries with a high degree of complexity.
- Advanced Analytics
Describes a wide range of analyses that are used to change and improve business processes. Unlike traditional analytics tools, Advanced Analytics tools do not focus on historical data, but on predicting future events. They enable ‘what if’ analyses and thus reveal the impact of potential strategic changes from companies. Examples of Advanced Analytics are procedures such as data mining or Big data analytics (see ‘Big data’).
- Advanced Robotics
Refers to the networking of industrial robots beyond the production line. The topic deals with the multidisciplinary aspects of robotics, for example with regard to the areas of mechanical engineering, computer science, control and electrical engineering, mechatronics or life sciences.

It can differentiate between function-oriented, file-oriented, object-oriented and Protocol-oriented APIs.
APQP is a structured methodology with standardised tools (FMEA, QFD, QM plan, etc.) which focuses on the idea of preventive error avoidance and continuous improvement in contrast to reactive troubleshooting. The time sequence, the application of the tools and the execution of the individual steps vary per product and complexity.
The APQP reference book was created by the Chrysler, Ford, General Motors Supplier Quality Requirements Task Force. It provides a guide for the early planning phase, development phase up to process analysis and thus provides a policy for creating plans and checklists to ensure that product quality planning is carried out by the supplier.
- Augmented Reality
Describes a computer-supported view of a real state that is enhanced by virtual aspects such as characters, graphics, GPS data, sound or text. Various functions such as the output of information about the current environment, work instructions or navigation are possible. A typical example is the well-known Google Glasses.
- Authentification as a Service
See ‘Jidoka’; refers to the independent work of a machine. In this case, the installation is equipped with sensors which detect deviations from normal operation independently and can be regulated in given areas. In the event of deviations outside the control possibilities, the machine can stop processing and issue corresponding warnings to the employee. The aim of the Autonomation is to increase quality.
- Autonomous transport control
Intelligent transporters navigate independently within the manufacturing network without central control.
- Container Kanban
The production/delivery order is created upon arrival of an empty container to manufacturing cell or Supermarket.
- Big data
Describes very large data sets that change frequently and contain very varying, complex information.

- Enterprise resource planning
Every part every interval, is used as part of the harmonisation of manufacturing. The goal is to manufacture each product in a defined time interval by using the smallest possible batch sizes. In this case, no less than the calculated, smallest possible batch size can be manufactured, since otherwise a Set-up collapse occurs.
- Event-driven information delivery
Information is always generated and distributed when there is a relevant event (e.g. attainment of a certain manufacturing goal).
Enterprise resource planning, refers to the needs-based time planning and control of internal company resources, such as personnel, material, capital, resources, information technology, etc. The target is an efficient Value creation process and optimal control of all operational processes. So-called ERP systems are used which effectively coordinate the various resources and business areas. The functional areas of such software include, for example, production
- Extended Signal Kanban
A variant of the Signal Kanban. Unlike the normal Signal Kanban, in the extended Signal Kanban the containers are provided with cards. If a part is removed, the Kanban card is hung on a Kanban board. Once the target batch size is reached (signal), the Kanban cards representing goods to be manufactured are ‘processed’.
- Ex-post quality control
Describes a quality control method carried out at a later point in time. This can generate data and information which would not yet be known at an earlier time. This ‘check in retrospect’ is often carried out in the form of audits.
- Failure Mode and Effects Analysis
The first in, first out principle ensures that the products run through the entire process according to their control order. It is in contrast to the humorous ‘FiNo’ (first in, never out) phenomenon, in which the parts within the process are swirled in the sequence and some only crop up again when a part hunter explicitly searches for the order.
- Fishbone diagram
- Fixed position stop
An instrument for quality assurance and is used in conjunction with an Andon board. Two ‘rip cords’ are attached to the production line. One of these is used to stop the line in emergency situations, the other to call a quality manager. If the Q rip cord is pulled, a signal with the station number is visible on the Andon board and the Q manager is called to the station to provide support. He or she now has time to solve the Q problem and delete the Q signal before the line gets to a previously defined point. If the Q manager is able to eliminate the problem before reaching the point and cancel the signal, the line continues. If not, the line will remain at this point until the problem is solved and the signal has been deactivated. A message is often sent to production management if the line remains stationary for longer than a previously defined time because of the Q message. Management is then requested to take a decision on resuming production or extending the manufacturing downtime until the problem is permanently resolved.

- Preventive maintenance: A regular maintenance plan for the machines/plants is developed with the employees.
- Scheduled maintenance programme: For the strategic orientation, a decision is made according to which programme the machines are to be maintained or repaired in the future. A distinction is made, for example, between time- and condition-based maintenance, break-down maintenance, etc.
- Training: The machine operators are qualified in maintenance tasks and preventive maintenance so that they can perform the maintenance in accordance with the requirements, and can also actively input their experiences and ideas during the next stage of maintenance prevention
- Maintenance prevention: This stage is about optimising and reducing the non-value-added maintenance activities without long-term losses in machine availability.
- Toyota Production system
Toyota production system, is an integrated socio-technical system, developed by Toyota, that comprises its management philosophy and practices.
Total quality control is a continuous quality control (assurance) of all products and processes that the company manufactures or executes.
Total quality management, holistic quality management
End-to-end Traceability and allocation of all relevant data and process parameters of products, components, batches and serial numbers.
- U cell
U-shaped production assembly cells, also called a Chaku chaku line, in order to keep wastage (e.g. long transit distances) as low as possible (see 7 types of Waste). This type of production is often found in mechanical manufacturing and also in assembly lines.
Waste type according to the 7 types of Waste. Overproduction refers to the manufacture of goods that exceed demand. It comes about due to an imbalance between the actual needs and the coverage. Overproduction is considered a major Waste form, which also provokes many other kinds of Waste.
- Cause and effect diagram
see fishbone and Ishikawa diagram. Graphical representation of causes that lead to or significantly influence a result.
- Use case
(Application case) describes the functionality of a system in event steps by defining interfaces and interactions between the Actuator and the system (Actuator environment) when tracking a selected goal. In this case, an Actuator can be any object that is directly connected to the system (human, machine, time).
Production levels are controlled in accordance with the actual consumption of the finished product, i.e. the quantity produced exactly matches the amount consumed in a defined period of time.
- Networked sensors
Integrated sensors, which (usually) have an autonomous power supply and (at least partially) process data directly on site and communicate wirelessly with one another.
All activities that consume resources but generate no added value. See 7 types of Waste or 7W
- Vertical integration
Means the procedure followed by a manufacturing company to integrate upstream or downstream manufacturing steps into its own manufacturing process. The less the company sources externally, the higher the degree of Vertical integration. The procedure is used to optimise the value chain and is therefore closely linked to the question ‘make or buy?’.
- Virtual factory planning
Digitization of all relevant resources and products; combination of movement/processing simulation and dynamic flow simulation.
- Visual management
- Information exchange: Employees share information that is directly or indirectly related to their work, thus promoting ‘independent thinking’ and initiative among employees. The information can also be used to control individual processes. For example, for a follow-up control in the sense of Kanban. If a storage area is empty, a new container must be produced, etc.
- Communication of working Standards and procedures: Explicit knowledge documentation of information relevant for work.
- Visual design of workspaces and processes: Creation of an overview that allows any form of deviation from the target state to be recognised. This naturally presupposes that target states have been defined.
Vendor managed inventory, describes a logistics concept in which the supplier has access to the customer’s inventory and demand data. The customer’s inventory is completely managed by the supplier and restocked as required. Three forms are defined: continuous replenishment, classic VMI and consignment inventory.
- Adaptable production facilities
Manufacturing plants are able to flexibly produce different workpieces or products without set-up or adaptation costs.
- Workshop fabrication
Manufacturing organisation form in which machines of the same function are arranged in groups.
- Value analysis
Analysis technique in which a work plan using a function analysis leads to significant optimisation of products and processes.
- Value creation
All activities that increase the value of a product or service; i.e. everything that the customer is willing to pay for.
- Value stream
All the working steps that are necessary, within system limits that must be defined, for manufacturing a product.
- Value stream mapping
- Value stream design
Refers to a method for holistic process optimisation. Here, material and information flows and temporal linking of the production steps from the supplier to the customer are considered holistically. Partial segments from this process can also be considered/analysed.
Describes wireless technology used to connect to a wireless local area network (WLAN). Actually, the expression WiFi refers to devices certified by the WiFi Alliance according to their specific Standards. Today, however, the term is generally applied to all WLAN-enabled devices.
- Cell production
see island production. Cell production is characterised by:
- Manufacturing in Takt time
- Working in One-piece flow
- The cells are planned with simple and easily set-up equipment
- The stations process the product autonomously
- The linkage of the stations is mostly done manually
- The lines are constructed in such a way that they can be operated by a single person
Benefits: increased flexibility, improved transparency, shortened throughput times.
Is a specification based on IEEE 802.15.4 for wireless networks that transmit simple data in limited, personal areas. It is usually cheaper and simpler than other personal area networks such as Bluetooth or WLAN. Typical applications are household appliances, lighting technology or sensor networks.
