*Latest webinar: 11/1/18 QI Macros Webinar

Over 50 people signed up for this webinar, with Jay Arthur demonstrating how to use some of the useful features of QI Macros, as well as some of the brand new features introduced just last month in the October 2018 version of the software.

Some attendees were familiar with the software and already use it, some had only begun to use it; all were interested in learning new ways that QI Macros can help them with their Agile Lean Six Sigma and Quality Improvement efforts. (You can hear him answering questions and comments typed in by webinar attendees.)



If you saw a feature demonstrated in the webinar that might have been added to QI Macros after the version you’re using (for instance, the “Find Tool” search feature or the automated Value Stream Map), you may need to purchase an upgrade to bring your QI Macros to the current version.

Big Data Bust

A recent TED video showed that Big Data is a $122 Billion Dollar business, but 73% of projects failed to return a profit. That’s a one-sigma performance. You don’t need big data. You can get big profits from small data.

Signal versus Noise

“Our evolutionary instincts sometimes lead us to see patterns when there are none there. People have been doing this all the time – finding patterns in random noise.” – Tomaso Poggio

People just need a way to separate the Signal from the Noise.

Here are some insights from the book by Nate Silver.

It’s Hard to Do Data Analysis on Ugly Data… Part 2

People often get stuck before the “Analyze” phase of DMAIC because of ugly data.
You can’t analyze data until it is in the right format for analysis.

In this data about medications that might affect patient falls, we have to:

  1. Transpose the data
  2. Use Excel’s Text-to-column feature to split the meds into separate cells
  3. Use QI Macros UnStack Columns tool to get all of the meds into a single column
  4. Use QI Macros Data Mining Wizard to create a PivotTable and Pareto chart of medications involved in patient falls

It’s Hard to Do Data Analysis on Ugly Data

I have found that people often get stuck before the Analyze phase of DMAIC because of ugly data.  You can’t analyze data until it is in the right format for analysis.

In this example of patient falls data, we have to:

  1. Transpose the data
  2. Use PivotTables to summarize the data
  3. Use a c Chart to plot the data.

Will Automation Steal Your Job? Skills to Beat AI

The March-April 2017 issue of HBR has a survey of 1770 managers in 14 countries. When asked to identify the top 3 skills needed, the managers identified two that are important to quality:

  • 31% of managers said  Data Analysis and Interpretation
  • 20% said Quality Management and Standards

QI Macros New Data Mining Wizard can dramatically accelerate anyone’s ability to analyze and interpret data.
Quality management is process management and statistical process control (SPC). QI Macros can do that too.

People skills were another key focus: social networking, people development, coaching and collaboration.

Nobody Wants to Read Your Spreadsheet!

Nobody wants to read your spreadsheet! No matter how hard you try to make it pretty, create great labels or whatever, the only person who can read your spreadsheet is a CFO or Excel spreadsheet geek. And the Excel geek is going to tell you 10 ways to make it prettier.
