behaviors of leaders and thinking processes in dealing with
- The importance of seeing things / situations with your own
eyes, as it allows all sorts of things that you can question and
- Practice simulations of actual events before they happen.
Have a reaction plan. Let it be modifiable.
- Have a command center
organize and formulate communications, coordination
prepare back up plan and unintended consequences
anticipate what might happen next
- Prepare relentlessly and eliminate making assumptions
All leaders are influenced by those who they admire. Reading
about them and studying what and how they learned will inspire
how you will grow critical traits. Much of the material will be the
raw material of your own life.
- insist on starting off with a morning meeting as your cornerstone

- sweat the details and small stuff, as they reveal underlying
- create arguments for different coalitions to influence decisions
- instill preparedness
- put your health as a first and main concern
- take as much time as available to make decisions, but the
process of making the decision should begin immediately.
- seek different perspectives and points of view, yet avoid
predetermination or favorites. [Sometimes it is beneficial to

word choice makes a difference
- stand up to bullies. Do it early.
- do not exceed the ‘pig factor’ [spending more than needed,

The book by Adam Alter is interesting reading from a |
number of perspectives. Irresistible– The Rise of Addictive
Technology and the Business of Keeping us Hooked
Alter asserts that addiction is not genetic in certain people
but every person is vulnerable to situations and attachments
to them. The Internet and various programmable devices
with continuous positive feedback,
- persistent “goals” culture,
- games and media that incur ‘down the line’ charges [get
you into it so you must and want to stay involved. But
to do that you have to pay.]
- escalation [where you get challenged and learn, yet the
computer enhanced tool increases or varies from its
otherwise predictable trend]
are examples Alter provides.
These addictive technologies develop habits where
you have little control. Nearly everyone of us has
our own and various situations make us instinctively
crave for that infernal habit.
Alter does readers favors by pointing them out,
showing what is going on and suggesting things we
can do to forestall, limit or move on to something else.

SCIENCE AND THE LIMITS OF DETECTION
SOURCE: S. N. Deming, Amer. Laboratory June/July 2017
Deming teaches in this article L(D) the limit of detection, which
he points out is different than the smallest amount of
analyte that can be detected or the limit of quantitation (appearing
in future articles.).
He points out:
- false positive risk needs to be appropriate for the application.
[drug testing example]
- in a plot of a calibration curve with a non-zero intercept, L(D)
the limit of detection is the amount of analyte that yields a
signal outside the error of the false negative.
These comments are often not brought out in many classes.

After our formal technical training, which may be experiential,
[non-academic] but most often involves the academic realm–
BS, MS, PhD and post-doc, many in government, industry and
entrepreneurial career paths find business certification a very
positive growth dimension.
This can happen when we choose to continue formal academic
work with an MBA or 13-week MBA certification. When we
explore this option we find 2-year and 3-year MBAs where the
longer term allows developing specialization skills. The 13-week
in-residence programs had prerequisites of solid business experience
and tighter admission and stronger longer term career commitment
from a sponsoring organization.
One clear strength of the MBA programs is the networking, both
formal, through the university, and informal, through connections
and associations (alumna, alumni).
In the 1980s formal business certification programs were developed
in parallel to MBA programs. These should be of interest to many
people since they may be more specific to certain aspects and
more broadly respected as providing necessary background and
organization useful in certain fields. These are the PMP Project
Management Professional and Six Sigma “Belt” programs.
I am surprised that ACS has not incorporated both of these in
career continuous education plans.
Six Sigma asks about understanding customer requirements and
mapping a process to identify and measure defects, losses and waste
using statistical methods, measurement systems and data analysis.
The training in each seem to differ and it is worth noting PMP

This year they contacted me. So as you have so many times emphasized,
networking is key to getting one’s resume noticed.
Career is a Process:
A senior level manager:
- Asked about my industry experience and was probing about my interests,
strengths and ability to work in a team. We really clicked in the interview.
It was a pleasant conversation about various aspects of manufacturing, QA,
QC , work ethics, and honesty. he was very pleased that I was familiar with
Quality Management System. I felt we were already colleagues in the interview.
Among questions asked:
- what I do not like, and what I like.
- given a situation what do I prefer: perfect and late, good and on time, or quick
and early…something like that. I elaborated on each as it all depends according
to me. For example, I recall saying it depends on how critical it is. In a situation
where you are looking at an API, it is critical to be within the acceptance
criteria/specifications, better be late but safe. But for a report, as long as all
the important information are there, I won’t delay it for perfection. I recall also
talking about how in a team, different people have their own preferences - in
terms of how to present a table. I personally don’t like to delay output for these
things (as long as it is not wrong).
Another Interviewer/non-technical manager:
- were able to relate a little as I had previous experience in the finance
department when i was in accounting.
- ended up in a conversation about the market, competitive advantage, pains
of month/year/quarter ends.
- Talked about SAP and Oracle.
- He actually appreciated that I knew about science and financial side of the
After Action Review:
- if I run into a situation like that again, I should transition my mindset into a
“sales pitch”- meaning, I should do the best I can to use facts from my
experience to support each criteria they are looking for.
- asked to visit the lab and areas of interests. I found it odd they did not propose.
So often articles and blog entries talk about hiring trends
for recent graduates. When I peruse them, it seems most

certain concepts) or statistical summaries that are often time

3. fall behind in your learning curve of new skills and experiences

a wide variety of disciplines from project management and
accounting, to analytical services, to quality control.
FL contacted me from outside the US about negotiating
a higher salary at a 10 year old company where a network
member currently works. FL was offered a position for six
months, after which there would be a review to determine fitness

I did approximate using estimated analogies.

FL sought a $10K improvement. So we reviewed areas of
possible approaches– spousal health insurance, no relocation
expense, day care needs, hours of work, self improvement plan,
other deferrable benefits. Since FL’s spouse has family health
care coverage and there are no relocation needs, these could be
offered as “give ups” to measurably increase salary. FL is flexible
for hours of work and has no immediate day care needs.
