5+ Whys

intro image

The 5 Whys tool is a commonly used method for Root Cause Analysis. It is often seen as a simple process of asking the question ‘Why?’ five times to uncover the underlying reason behind a problem. However, this perception is not entirely accurate. The 5 Whys is actually a powerful creative thinking tool designed for thorough problem analysis and resolution.

Here, we present a modified version of the 5 Whys tool, incorporating concepts developed by PRIZ Guru Inc. This modified version offers the following key features:

  • Comprehensive Problem Analysis: To facilitate a more detailed analysis, we introduce the 5+ Whys tool, which encourages an extended sequence of ‘Whys’ to dig deeper into the issue.
  • Root Cause as a Source of Solutions: While identifying the Fundamental Reason of the Problem (FRP) is important, it may not always lead to problem resolution. We emphasize that a Root Cause can also be a source of solutions, with each step potentially contributing to a solution.
  • Machine Assistance: Incorporating machine assistance can be valuable during the search for root causes and the creation of solutions, streamlining the process.
  • Effective Ideas and Solutions Management: The 5+Whys method places a strong emphasis on ranking ideas and solutions, as well as making informed decisions, ensuring a comprehensive approach to problem-solving.

What can you gain from using 5+Whys?

The 5+Whys technique is a valuable tool for creative thinking that helps break free from psychological inertia. It redirects our focus towards a logical analysis of sequential causes and effects. By utilizing this tool, we can achieve a deeper understanding of systems and generate effective solutions. Here are some notable benefits associated with using the 5+Whys technique:

  • Improve your understanding of the system by identifying its most problematic aspects.
  • Shift from guesswork to generating reasoned solutions and ideas.
  • Establish pathways for future system development.
  • Cultivate effective problem-solving within your team.

When should you use the 5+Whys tool?

The 5+Whys tool is highly effective in providing quick responses and is invaluable in various scenarios. It is especially useful for addressing unexpected parameter deviations (excursions) and analyzing and resolving chronic problems. Some notable applications include:

  • Dealing with unforeseen deviation.
  • Improving Key Performance Indicator (KPI) metrics for chronic issues.
  • Promoting innovation and process optimization.
  • Supporting continuous process and product improvement.

Furthermore, the 5+Whys thinking tool is versatile and can be applied in numerous other contexts to harness its creative problem-solving potential.

Recycling waste of solar panels.students: Alaa & saed

Excited to share our latest project at Ben-Gurion University of the Negev! 🚀 We tackled the pressing issue of solar panel waste and explored innovative recycling solutions to make solar energy truly sustainable.Key insights:Solar panel waste could hit 78 million metric tons by 2050. Only 10% of panels are currently recycled in the EU. Our project highlights the need for efficient recycling technologies, better regulations, and economic incentives to drive sustainable practices.Let’s work together for a greener future! 🌱

SiO2 thin film creation in Diffusion furnace - Process Functional Modeling

The process is related to microelectronics - microchip manufacturing.The purpose of the process is to create a SiO2 layer on the surface of a Si wafer. Equipment: Vertical furnace to heat the wafers in the Q2 atmosphere and perform oxidation on the wafer surface. Process: The oxidation occurs on the front side and on the back side of the wafer Requirements: Create a SiO2 thin layer with a certain thickness and low sigma - low standard deviation of the thickness between the wafers and within the waferFailure: Wafers from the lower zone have higher thickness and significantly higher within wafer sigma (standard deviation of the thickness within the wafer)

Wafer cleaning issues at the wet process

Wet cleaning is widely used in microchip manufacturing. Single wafer equipment is working as follows. A wafer rotates, and chemistry is poured from a movable nozzle. Water rinsing is performed at the end of the process. Loading of a new batch of the chemistry resulted in excursion - a strongly increased amount of defects was observed on the wafer after the processing. The project is dedicated to the failure analysis and creation of innovative solutions.

Magnetic PDMS micro-pillars

In past decades, polymeric micropillar devices have gained a great deal of attention in micro and nano technology research as the result of their potential and practical usage in many applications. This project is going to deal with the process of how to fabricate the magnetic micropillars, from the beginning – the planning and design, improving the existing process, lithography to create the base silicon mold and then creating the PDMS pillars that contains nano magnetic particles of Fe_3 O_4, the process today is not efficient enough in terms of cost and time and we are wishing to improve it, in the end we will have a device with micro-pillars that can move correspondingly to external magnetic field which will help us to do many advanced experiments in the biology field like using the device for cell stimulation.
