How to measure the effectiveness of product usability

I have worked for many products using in healthcare, Power automation, building automation, Aerospace where user interaction is very critical, every steps impact in certain way. A small mistake can cause human life.
Mission critical Software product has to develop considering user effective usages, how efficiently user can use it and what is the user confidence level, comfort level. It is not the UI or look and feel , but it is the usability which will tell the product management team about the effectiveness of the product under specific environment, specific circumstance how easily , efficiently user can use the product.

According to ISO 9241, Part 11, usability is “the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use.”2 This definition ties a system’s usability to specific conditions, needs, and users—it requires establishing certain levels of usability based on the five basic attributes.

It is
“A process through which usability characteristics are specified, quantitatively and early in the development process, and measured throughout the process.”
Usability techniques, therefore, can help any software system reach its goal by helping the users perform their tasks. Furthermore, good usability is gaining importance in a world in which users are less computer literate and can’t afford to spend a long time learning how a system works.
Organization will not able to capture the market effectively if they ignore this factor. Likeability factor for product has to go up. We cannot command our customer to buy our product. The product which will get great customer satisfaction will sell like hot cake. The good amount of engineering marvels will not help in long learn if it is too complex to use.
How do we measure that product is in excellent shape to use:
The system should always keep users informed about what is going on through appropriate feedback through reasonable time.Systm should have good way of communication with the user through well define understandable format.
According to definition below parameter are good to tell about the product usability:

a) Learnability: how easy it is to use the software for an average user without much background.

b) Efficiency: how fast user can operate the system

c) Mistake: how many mistake users do while executing certain operation?

d) Easy usage: how easy to use the system or remembers the steps after long gap.

e) Satisfaction: will operator appreciate about the product after usages

How can we increase user efficiency and satisfaction and, consequently, productivity?
Techniques, therefore, can help any software system research its goal by helping the
Users perform their tasks.

How do we have done our feedback collection?

a) Inquiry
b) Inspection
c) Testing

We have created user profile with right users. All kind of users we have done various tests to get the feedback from all the team members. We have consolidated the inputs and brainstorm to complete the gap analysis with the current system.

A conscious mind nurtured by spiritual thoughts, however can solve a stress related problems.
It is very important for all of us to consciously guide our mind to pure thoughts.
The new art of science and medicine, a current medical journal, the readers digest quoted a remarkably similar comment: "The only way of tackling human disease is by purifying the soul and changing its vitiates life stream"

Mans belief that materialism, consumerism and ambition are desirable goals of life is the result of wrong tendencies rooted in immature minds.
These are unspiritual goals that cause stress and illness. james allen calls them "Unlawful" To give life meaning we must constantly nurture our mid with good thoughts and good ideas, The mind affects our mental and physical state if health or disease.
One's mental affliction or weakness afflicts others.
We don not cultivate our mental strength.
We waste our mental energy in many ways.
Our haphazard reading habits have no definite purpose.
Our garrulous arguments are selfish and satisfy only our ego.
We always interested in affairs of others with our best curiositty.
we brood, we find fault, we feel superiors.
A weak mind is an unhealthy mind. It will never find peace.
A strong mind is identical to a peaceful mind.
Healthy imagination plays key roles in curing disase.
we have to visualize excellence in our physical well being, Body and mind work together. The healing system is the way the body mobilizes all its resources to combat diasease; the belief system is often the activator of the healing system.
How one responds intellectually, emotionally - to ones problem has a great deal to do wit the way the human body funxctions, One’s confidence or lack of it in the prospects of recovery from serious illness affects the chemistry if the body.
The belief system converts hope, robust expectation and they will to live into plus factors in any context of forces involving disease, the belief system is no substitute for competent medical attention in serious illness or vice versa, both are essential, The belief system is not just a state of mind. It is a prime physochological reality.
The greatest force in the human body is the natural drive of the body to heal itself=== but the force is not independent of the belief system, which can translate expectation into psychological change.
Everything begins therefore with belief. Today’s world the greatest of diseases, rot cause of all disease is stress.
Mental stress is root cause of all disease.
we cannot avoid stress in today’s world, but we need to learn how to handle stress.
Stress is killing people as most of us ignore it and internally it is causing lot of damage, Emotional insecurity leads to the major symptoms off worry, self pity anger, and depression. All physical ailments are provokes by emotional disturbance. Emotions are not generated spontaneously.our emotions flow from the thinking pattern of the mind. We need to train our mind to control emotions. Simple breathing exercise can control our mind in greatest way. It THE BEST technique to control the mind.

Physical disease may be balanced by a positive mental attitude and social support so that overall stare in one of well-being, other hand emotional problem cause person feel sick in spite of physical fitness. If we continue to cultivate the lower self by identifying with the body and mind, the unhealthy thoughts and feeling we harbor will cause u to have a mismanaged fate on our death bad. We can not live our entire lives nurturing our lower impulses and expect to get rid of them when the last, moment arrives
