Who solves the problems?
Problems continue to arise so quickly that we find solutions and shortcuts to temporarily alleviate voltage points - so that we can move on to the next problem. In this process, we fail to eliminate the root cause of every problem that arises and we are trapped in an endless cycle that makes it difficult to find real solutions. Does it sound familiar?We all have problems that we face in our daily activity and life, it seems that there is never enough time to solve each one without facing...

Who is responsible for PFMEA?
Responsibilities within the organizationWhen an organization decides to use the PFMEA methodology one of the first questions that arise is about responsibility for the process… and usually after this time the organization gets stuck in a long series of negotiations in the management team, usually between the engineering and quality departments.The ambiguity arises from a poor understanding of what this responsibility means or because of the behavior of that organization in terms of (non)...Read this article...
IATF - remote audits during COVID-19
The spread of the COVID-19 pandemic affected all branches of industry, with automotive production being one of the hardest hit.In addition to the existing problems in 2019 with the availability of labor and the decrease of orders, there was also a less known and discussed issue, the conduct of audits in pandemic conditions.Due to the pandemic, many organizations were forced to discontinue their activities for a shorter or longer period, which in many cases led to the expiry of the IATF...Read this article...
Setting the objectives; SMART
Companies that want to achieve performance need to develop an organizational culture based on goals. And of course these related to performance evaluation for both top and middle management and for individual employees.Starting from the CEO's vision and strategy, the long-term objectives of the company are defined and they are later broken down at the level of the organization's structures and finally at the individual level.The power of goals lies in how they create both an action plan for the...Read this article...
Prioritization; Make the most of opportunities
During the improvement process, after defining the problem, collecting the data and analyzing them, decisions must be made regarding the choice of optimal solutions to be implemented.After finding the root causes, the project team can generate several improvement ideas, only a few of which need to be selected based on an objective assessment.Prioritization is a decision-making, rational process that is achieved through criteria. Most of the times, when the team members find the best criteria,...Read this article...
How much do we plan and how much do we leave (planned) "at random" ?
n our "Production Planning" courses, when we get to the capacity calculation of production capacity and especially how much we choose to fill capacity, many participants have the same frustration: WE KNOW (it is 100% sure) that we will have variations in customer orders , that there are problems with machines and equipment (it does not work at 100% capacity), that we do not have enough operators sufficiently prepared, but we insist on planning at theoretical capacity (maximum). "We know" and...Read this article...
Sampling
Data must be collected to perform analyzes, studies, graphs, or to demonstrate improvements after a project.
Collecting (measuring) a lot of data can sometimes be very expensive, it would require a lot of time and resources. For this reason, we are working with sampling.The sample is a significantly smaller extract of the population used to make a deduction and relate back to the population. Usually the most common deductions are average and standard...

These...Read this article...
Choosing Six Sigma Projects: A Challenge
Six Sigma projects generally addresses to more complex problems, for which no solutions are known.Initially, when creating the methodology, the vast majority of projects started from VOC (Voice of Customer) and lately, especially in times of crisis, such as the one in 2009, the VOB (Voice of Business) approach was also observed - in fact a reduction in costs.Many projects are chosen from KPI (Key Process Indicators) to be improved.These could be: defect rate, preparation time, equipment...Read this article...
The purpose and advantages of an ANDON system
In Lean production, an ANDON refers to a tool that is used to inform and alert workers about problems in their production process.The term Andon comes from a Japanese word for the traditional paper lantern. An Andon is one of the most common forms of visual management that is used in Lean. It is an extremely effective tool, as it allows the operation to work without problems, without blockages. An ANDON is a system that helps the flow of information on the status of the production...

MUDA (Waste - identification and categories)
The activities are divided into two categories: activities with value (VA) and activities without value (NVA).Dumb / waste is defined as any activity that consumes resources without creating value for the customer.
Besides MUDA, there are also MURA and MURI, but both lead to MUDA.
The first means unevenness / imbalance between operations, in processes. MURI, refers to the overloading of equipment or operators.
Non-value added (NVA) activities can be divided into eight...

Hypothesis Testing: Continuous Output vs. Attributive Input
Sometimes, in practice, we want to make sure we make the best decisions. For example, we want to choose for deliveries in the city, the fastest option between scooter and van.We will use hypothesis testing, a method of proving beyond any logical doubt that a statement is true or not.A number of statistical tools are used for data analysis, the application of which depends on the type of input and output data.We issue the null hypothesis (H0): The delivery time is the same for both means of...Read this article...
The link between FMEA & Control Plan
Common mistakes that impede performanceAre we conscientious users of the FMEA and the Control Plan and still have problems? Then we should be careful that:1. The FMEA should be aligned with the Control Plan process steps.The process steps must correspond to those defined in the Flowchart. Each line in the FMEA must have a corresponding line in the Control Plan, more precisely for each risk identified in the FMEA we must have a control for prevention or at least detection in the Control Plan.2....Read this article...
Graphical Analysis: Pareto and time chart
Graphic analysis is "the method of analysis that performs the graph by taking data from data tables." We learn from interpreting data about the nature of the process and where the sources of variation come from.The Pareto Chart, also called the 80/20 rule, which specifies an unequal relationship between effort and effect, helps us to prioritize actions. It was named after the Italian economist Vilfredo Pareto, who observed that 80% of Venice's wealth was owned by only 20% of the population....

Why do we need a Quality Department?
One point of view: Why do we need a Quality Department?(or Why Production Can't Without Quality)
In society, fire prevention is generally considered to be everyone's responsibility - and yet it cannot be done without professional firefighters.
Similarly in an organization, no matter how Lean it is and everyone's dedication to maintaining quality, we will have problems reported by customers. Some of the immediate questions are:
To whom does the client address the complaint?
Who reacts...

Speed, Quality, Cost - Meaning and use
The Speed-Quality-Cost Triangle is also known as the “Management Triangle” of the project (also called the triple constraint) which is a model of constraints in project management.What is essential is to balance all three, so that performance is targeted for each. There is no point in improving speed by increasing costs or reducing quality.
It is also known as the "Application Triangle" or "Quality Triangle" and shows the inherent trade-offs of any project.
In the normal...

Point of view: Collaboration of the Production department with the support services (logistic perspective)
I suggest you do an imagination exercise: try to imagine a client, the most difficult client you have. Add to this customer the image of "very important" even if it is not, the image of "I need and I do not care how you do" even if it generates costs higher than the value it produces, a customer who has some indicators measurable defined for his activity and to achieve those indicators does not care about others around him. Any attempt to communicate to improve relations and, consequently, of...Read this article...

Hypothesis testing: Basic principles
During the problem-solving process, especially in Six Sigma projects, we are put in a position to statistically prove relationships between various process outputs and parameters that are suspected to influence them. The causal relationship is based in statistics on what is called hypothesis testing.For example: we want to improve the hardness of a metal part and the potential factor is the cooling rate.
Hypothesis testing is a formal procedure for investigating and proving the causal...

8D Problem Solving? Procedure ?
It often happens that in the production process we have problems of quality, flow, cycle time, organization, supply, etc. In the literature have been developed several tools that define methodologies for solving more or less complex problems depending on their difficulty. Obviously, the ‘price paid’ for the application of these methodologies varies depending on the instrument chosen.Analyzing these problem-solving methodologies, we drew attention to the 8D method that helps solve...

Do we really need the MSA procedure?
Today's production companies collect a large amount of data, through measurements and inspections, on the basis of which decisions will be made with an impact on processes and business in general.Inspections performed either automatically (more and more often) or by specialized personnel, can also generate erroneous decisions, with effects in artificially increasing defects or sending non-compliant products to customers. In both situations we lose money and even customers.
To prevent these...

What should an SPC procedure contain?
Knowing that all production processes have some variation, about 100 years ago Walter Shewart discovered a way to distinguish between common causes and special causes of variation in a process. Shewart also understood the danger of "firefighting" actions to react and act depending on where individual values are located in relation to the tolerances of a process.This discovery of Walter Shewart, together with the methods developed later, is today called statistical analysis of a process...

Efficiency of Warehouse Activities
Do we have enough resources? Correct answer: I don't know!Efficiency means the extent to which the effort or resources consumed generate value for a process.
How efficient are the activities defined in your warehouses? For the efficient measure in the logistic activities we must first of all have defined the processes and the activities in the warehouses - do we have them?
Are the responsible persons qualified for those activities? Are times defined for each activity (norms) and can...

Optimizing Warehouse Space Use - How to Get More Resources?
Both in Production and outside the production area one of the most expensive resources is space. When we enter the Logistics area and we talk about warehouses and warehouse service spaces (access roads, loading / unloading ramps, parking and waiting areas) the space seems more and more important and more expensive.

Production Planning - The Supreme Purpose !
In any production organization as well as those in the sphere of services, there are products that are made easier or harder or some with high loss rates (scrap and remedies). In general, it is considered that if we leave Production Planning (PP) to Production, we will only plan products that are easy to make with a small scrap, with a generally high productivity, but to the detriment of those for whom we have demand. On the other hand, PP switched to Logistics can decrease productivity but...Read this article...
