The Gantt Chart Dilemma

 
To Gantt Chart or Not to Gantt Chart                                                                                   
That is the question
Whether tis nobler in the mind to suffer
The risks and hassles of possible failure
Or to take steps against a sea of potential troubles,
And by detailing every step end them? To not fail: but to sleep;
No more; the troubled sleep of anxious mind.
The heart-ache and the thousand natural shocks of a disturbed nights sleep
The doubts which creep into the minds subconscious
For is it worth the time and effort taken
To detail a small project.  Verses the satisfaction:
Of knowing a thorough job will minimise the chance of failure
Devoutly to be wish'd. To not fail, but to sleep;
To sleep: perchance to dream: ay, there's the rub;
For in that sleep of success what dreams may come
When we have shuffled off this mortal companies payroll,
Must give us pause: there's the respect of a job well done
But a calamity will stick and have a long life;
For what Engineer would bear the whips and scorns of time

Air Over Hydraulics

 
How do you achieve the power, precision, flexibility and reliability of a hydraulic system from  a  standard  compressed air supply ?

Many times in Engineering design, there is a need to deliver the characteristics of a hydraulic system without the costs of a full hydraulic system.  Generally compressed air is readily available in most applications.  Even if its not, the cost of supplying compressed air is usually much less than an equivalent hydraulic system.  There are ways to boost the performance and characteristics of pneumatics but the cost and complexity (read reliability) increases exponentially and it is never the same outcome as a good hydraulic system.
Before settling for a pneumatic design which may not supply the ideal performance or characteristics, consider the advantages of an “Air Over Hydraulic” system, such as the units supplied by Enerpac.  
I have successfully used these units in a number of applications requiring precise control, at a very reasonable cost.  
Obviously they are not going to suit every application but I would certainly recommend that they be considered as a viable alternative.

A Round Tuit

 

There have been references to Round Tuits since Adam was a boy and I'm sure that most people must have searched for them at some stage in their lives. However, for the few who haven't had a need, this is a mythical Round Tuit


                                                                       
As you can see they would be extremely useful and could potentially be used by many people who would complete many more tasks, if they could only get a Round Tuit

Why The 5 Whys

 
Most Engineers are logical, its in the genes.  
It therefore follows that there should be a formalized logical approach to the intangible process of analyzing and solving problems.  
A very simple and easy to use system is “The 5 Whys”.

CMMS Garbage In- Garbage Out

 
Whether its a Super Computer or a simple CMMS the same principle applies.  Garbage In – Garbage Out.  It's common sense, but as the old saying goes – “its surprising how Uncommon Common Sense can be”.  If its not working for you, it will work against you. All data being put in to the CMMS needs to be of the highest quality.

Computer Maintenance Management System: Capture the Data – Close the Loop

 
A well thought through, well designed, well installed and well managed CMMS is a valuable asset to any company but it doesn't happen by accident.  There needs to be an unwavering commitment in order  to get the maximum return from what can be a significant investment.  Unfortunately many companies start on the journey, but never quite get to the destination.
Most Computer Maintenance Management Systems (CMMS's) have the ability to “Close the Loop” with jobs and this is a feature which is often not fully utilized.  Closing the loop means capturing data from the work sheet and using it to improve the process

The Computer Maintenance Management System (CMMS- is it working for you ?

 
If I've heard it once, I've heard it 100 times (and more)
“Well yeah, we run a CMMS but we don't use it the best”.  
It always amazes me that Engineers will freely come out with this statement and yet do nothing about it.
Invariably the company has made a significant investment in purchase, installation and at some stage training, but don't seem able to go the extra yard in order to get the full value from the system.

Bring Back The Slide Rule

 
 Old fashioned, dead, gone , quaint antiquity, confined to the museum of old technologies.
Well maybe, but maybe not.
I believe that use of the slide rule should be resurrected. Not only should it be a compulsory Engineering subject but Slide Rules should be an essential “tool of trade” for Engineers in the work environment.
Why would anyone want to use a slide rule with its approximation and need to think through the units and location of the decimal point when a simple calculator will give the answer to an accuracy to six or eight or 10 decimal points?

For that very reason - “A NEED TO THINK”
