Resistance to Change (2)

Friday, October 2nd, 2009

Legitimate Concerns
Either some adjustments are needed to make the proposed changes function properly, or there are hurdles or barriers that have not been considered. Perhaps the product / change / project / system does not meet the objecter’s expectations of quality (or other, such as technical level), or there are known issues that the salesperson would not reveal.

Feedback from other parties (different location or facility within the corporation, friends, colleagues, or other) may point out severe problems.

Very often, some person voicing a legitimate concern may not be capable of fully expressing the reasons behind their reticence (oddly enough). The objecting party “feels” the proposed solution to be wrong for their environment.

If consensus must be achieved, develop a checklist and discuss the proposed goals with the vendor / service provider, and never forget to get the agreement in writing, detailing the issues, what the solution will address, and how it will achieve this.

Resistance to Change (1)

Thursday, September 10th, 2009

The infamous “resistance” to any proposed change takes many forms.

There are legitimate concerns, there’s contrariness, there’s fear of change, there’s protectionism, there’s a confrontation with a history of failed or abandoned initiatives, and finally, refusal to execute the work involved in the implementation of change, which unfortunately amounts to plain laziness.

Arriving at a consensus within a group of people may well face every previously stated type of objection, making compliance and adoption of almost any novelty / improvement / project difficult or even impossible at the best of times, no matter the value of the proposed initiative or change.

Over the course of the next few days (we hope), the author will endeavor to write out a few thoughts on each of the above.

Contrariness
The contrarian takes two forms: he can be a naysayer to anything he does not himself initiate, and thus, becomes a negative influence and rarely a helping hand in any of the activities of the group, corporate or otherwise, or he can be a conscientious critic of unlikely, unpalatable, unreasonable, inefficient or ineffective practices, methods or proposed “advances”, seeking to ensure quality and thoughtful of achieving specific goals. Of course, whether or not the contrarian can deliver his message in palatable form remains a challenge, and the (often different or opposed) views tendered by said contrarian can clash with the majority or the view adopted by leadership. Both require considerable maturity to accept the opposing current and trigger intelligent discussions based on analyzing what that impopular person is saying to obtain the value or pointed correctives that his views may contain.

In the above, “unlikely, unpalatable, unreasonable, inefficient or ineffective practices, methods or proposed “advances”…” could merely signify that there may be room for better adjustments or they may be downright necessary: the person deemed a contrarian may merely seek a slightly better approach, or more bang for the (same) buck…

As examples… 
One anecdote I often use (and may even be found in another posting on this site) is the advent of the first Windows-based or Windows-compatible (the Microsoft registered brand used without permission, not the household-type) vibration condition-monitoring software. Given the current preponderance of that operational system or platform, the reader will understand a few years have gone by since the anecdotal incident.

That software’s main qualities were:
1) it was going to be first to market under the increasingly dominant Windows (see previous disclaimer),
2) it actually worked without crashing,
3) it simplified report printing and layouts, but only for what was now extremely basic (or entry-level) reporting.

The same software principal defects were:
1) It offered little except basic functions, made readily accessible not through any ingenious design, but merely through the Graphic-User Interface’s benefits,
2) the software did away with many of the useful application functions that were readily available under DOS (but of course, that was going to be rectified in the future, meaning probably never),
3) it cost a frightening amount of money

My attempts at making suggestions to achieve expansion from the foundation we previously had, as opposed to devolution in terms of application, were met with allusions to “resistance to change”, when in fact, the nature of my objections was “Nice eye-candy, where’s the meat?” or where was the substance to assist analysts in better doing their jobs.

Another valid example, when faced with various problems during a reliability audit done under another company’s auditing process (or lack thereof), was to ask whether the process had been the subject of an FMEA (Failure Modes & Effects Analysis). After all, if you sell the science, the execution and the mindset, you should be interested in applying all of the previous to your own product, whether physical or service oriented.

In the previous statement, my “or lack thereof” was unfair, and of the naysayer contrariness type: in all fairness, they did have a process, but the process should have been accompanied by clear directives and guidelines as to “do’s and dont’s”. The process should have benefitted from strong warnings against allowing corporate tag-alongs during execution. My suggestion that an FMEA would clearly have established problems with such a practice came from obvious hurdles such as the reluctance of audit interview participants to formulate their answers in the presence of a corporate representative.

Opposing views leads to (minor) confrontation, and people are increasingly uncomfortable with disagreement or argumentation. Yet, out of the clashes of ideas are born the better or even best solutions. HBR (Harvard Business Review) and other management article sources state that the increasing disappearance of differing opinion hurts business.

For the well-meaning contrarian, perhaps the road to Hell is paved with good intentions.

Bemoaning Analytical Costs

Thursday, March 22nd, 2007

We sat in with a (then) prospective customer having problems with a very special machine: one of a kind, a prototype really, made in Europe, highly-complex variable speed multistage planetary gearbox, with inverted simultaneous movements: a fun challenge for an analyst, but one that could rapidly turn to nightmare if sound methods were not followed in orderly or procedural fashion.

While we took a look at drawings, and commented, the meeting went on with the people in charge. “We’re losing $100,000 a day on reduced production!” Indeed, the vibration would get so bad as to limit speed, \commensurately reducing output.

Now for vibration analysis purposes, we need to do a speed-sweep recording of multiple channels of information to then compare reactions, and perhaps even build an animation. The problem obviously needs to be quantified before we can affirm anything, and the measurements taken by the customer proved fairly basic: lending a nebulous idea, but no great help in establishing the scope or nature of the problem.

We conferred, and stated a package price of $20,000 all-inclusive: measurements, analysis, report in both brief and full versions, presentation of report, engineered solution.

That’s when the roof caved in on us with the plant manager almost calling us names (along the lines of price gouger, and a few other terms punctuated with choice epithets). Pause… Shall we say it was clear the price was not to their liking? Yet, in the meantime, over a 90 minute meeting, they had allegedly lost $6,000.

Was the proposed price justified? Absolutely! We had a 12 hours 16-channel collection speed-sweep and variable-load sequence, data review (Simultaneous data from sixteen channels under controlled variation of recorded factors conditions requires ample time) and analysis, a possible (and rather likely) machine design review, a whole day of presentation possibly involving two persons. As a matter of fact, we were trying to deliver a fully-packaged, functional and feasible solution to an unknown problem at a reasonable price.

To the uninitiated, multi-channel work may seem a mere matter of unconnected information, but correlations need to be established: imagine recording 16 TV channels and then finding out if commercials are synchronized (or not), if there is an underlying contents programming emulation where all networks decide to show similar programs at the same time. Then, imagine that your need to cut up one channel’s contents in tiny pieces, or process it differently to isolate “dialogue”, or modify the contents of one channel in relation to another’s.

Within the context of this contract, synchronous time-averaging and order-tracking had to be completed in post-processing, high-resolution FFT cascades had to be extracted, and in this case, high-resolution means much more than 3200 or 12800 lines. Jitter and jerk even were assessed. A little structural work was done to complete the picture. Our Finite Element specialist associate also handled the case.

All this takes time. And the relationships and workings are not automated. A guiding intelligence must determine how best to extract what seems relevant to the mission.

Once the initial storm blew over, and the solutions implemented, all parties were content, but THAT is another story!

Additionally, one may read herein the key point of the nuance between detection and analysis: “detection” was here summarily conducted by intolerable vibration levels making the machine dysfunctional at its design speed, a status that was readily assessed using portable instruments, whereas analysis called for much more depth.
