Cleanroom Leadership Personalities: Are you Driving Success? Part 2

Check out whether your cleanroom management style will help or hinder the success of your employees and your business.

Knowing your own management strengths and weaknesses is important for any leader. You can’t truly evolve until you understand who you are, how you thrive, and what sets you back. We began explaining Randy H. Nelson’s four personality types for leaders in our last article. Here we will explain what the remaining two are and how people with these personalities can best succeed.

Reflexively Pessimistic: This person is always ready for a crisis. This person is a survivor; however, the constant focus on what can go wrong interferes with this leader’s ability to grow. He or she has no strong foundation of how to manage when times are good. Staying the course on a good day is just as important as righting the ship in a storm. A beneficial exercise to help this leader would be one similar to the one explained for the ever-optimistic leader. He or she should list the strengths and weaknesses of the major facets of business he or she leads. Following, this person should present this to colleagues with a focus on positive comments and forward-thinking plans.

Steady-Proactive: What Nelson says about this group is: “These leaders are clear in what they know and don’t know. This person has moved beyond a revenue-only focus and now devotes time and effort to understanding what boosts stock value, using this knowledge to push the valuation ever higher.” On the flip side, this kind of style doesn’t allow employees to relax and enjoy the moment. An exercise that would help this type of leader would be to have him or her come up with ways to stop and celebrate successes at least once a quarter.

Cleanroom Leadership Personalities: Are you Driving Success? Part 1

Does your personality help or hinder your employees’ and company’s success? Cleanroom managers: check it out.

Just as with all jobs, CEO and management positions tend to attract certain types of people. Some personalities work well in roles like these, and they are able to help the company thrive. Others struggle to succeed. Often times, managers don’t actually know themselves well enough to know the difference.

According to reputable business leader Randy H. Nelson, there are four major personality types for leaders. Here are the first two descriptions of personalities and what would help them succeed.

Urgent/Reactive: This person is not proactive, but rather waits until the last minute to take action. As Nelson says, “This business personality creates and thrives on an almost crazed atmosphere, where he or she can ride to the rescue, put out the fire, be everybody’s savior, then move on to the next problem. In other words, fix it and forget it. It’s characterized by action without introspective vision and premeditated guidance.”

According to Margery Weinstein, who writes for, these kinds of leaders lack introspection. For them, taking a personality test to gain personal introspection, and preparing a presentation of their vision for the company to gain professional introspection, would really strengthen this personality as a leader.

Ever-Optimistic: This person has a can-do attitude that is great for encouraging confidence and morale. He or she is enjoyable to be around and can propel motivation. However, when the going gets tough or the luck runs out, this person often doesn’t know how to react. Additionally, this person finds it difficult to deal with employees who are skating by.

Weinstein suggests that managers with these personalities list both the strengths and weaknesses of the major facets of business they lead and present it to a work group to collaborate on a plan to improve.

Testing Compressed Air Lines – Medical Device Manufacturing

If you’re a medical device manufacturer, you need to clean the air systems that clean your components. Here is some advice.

Compressed air is used in many applications for medical device manufacturers. While they are generally used to eliminate contaminates, the compressed air system itself can harbor microorganisms. This can adversely affect the product, so it’s important to routinely test your air lines.

Things to consider when scheduling your periodic testing include:

  • Increases or decreases in production schedules
  • Changes in the seasons
  • Changes and modifications made to equipment
  • Any hardware or dryers/filters replaced
  • System inactivity

The actual test should use air impaction onto growth media by reducing the compressed air pressure using a built-in or external regulator. Then attach a flow meter, adjust the flow to a suitable rate, and attach the prepared Petri plate with the air impaction sampler.

Your test equipment will likely include a Slit Sampler, or slit-to-agar sampler. This puts the Petri plate on a rotating stage to impinge the organisms onto the agar. The plate is then incubated so the microorganisms can grow.

There are a few things to consider when developing a sampling plan:

  • A longer sampling time is appropriate when the air system is static
  • A shorter sample time is appropriate when the air system is in use
  • Broad spectrum, non-selective media will enable the growth of too many organisms and overwhelm the process
  • Selective media, on the other hand, can potentially limit overall growth, giving quantitative counts.

A broad-spectrum agar like Tryptic Soy Agar (AGA) is a recommended medium for the growth of non-fastidious organisms. If you’re trying to isolate a certain type of microorganism, you can use something like Subouraud Dextrose Agar, which cultivates fungi.
