When i did passed out I did perceive that engineer should have knowledge of his particular faculties all the fundamentals so he/she/other can solve the problems and make it new level of upgradation. but still to make it simple and abstract three fields has been classified as Software,Device/Hardware and Networking.

and all this happen because skills and career option could be simplified as software need more logic and calculation and understanding regarding skill. in hardware/device he/she/other needs to be more accurate with circuits, assembling of ICs and soldering otherwise there will be huge cost in repairing or de-assembling or might be dis-soldering will happen. and in network all needs to know about operations and operations regarding protocols and protocols regarding configuration and configuration regarding tools.

On this level everything looks fine because all of this three fields required of relevant but still not highly dependent knowledge on each other. as software is mostly about programming, hardware/device is mostly about circuits making and networking is all about troubleshooting and configurations.

but what hacks me that how classifications in each of that fields happen that sounds completely ridiculous are most of computer engineers are become marketer of specific company or organization or become lazy professionals that does not have any more passion to learn or spin off to new or other relevant technologies. or Narrow minded people that just want to stick with known things and mindset. as In software field now there are no more software engineers or software developers there are .net develops or Java developer or PHP developers.

If you have worked on java and you go for .net than in most of firms you will be told that we don't work on Java and we want expert on .net. call you if there any requirement for java.

I know nower days most of firms in India are just a code shop. not driven by true solution oriented or product/service oriented company service ,problem and product lies outside of India and only code is written on their firm more you write code more you get paid. and if any specific code is already stacked by leaving of developer than new developer is needed to continue write that code. and ASAP start to continue. so money flow not get stopped. and that is why more than 86% code is getting written in India but still stay a lot behind in actual engineering.

I think in software industries there is need to understand actual engineering aspect instead of just selling code. and if there will be an approach to give solution to particular audience to provide service/product than there will be the need of specific alter techniques and need of understanding to be explored as Medium to small level software did not need to get distributed on multi-layer architecture so that can be easily deployed on Apache using PHP or ruby and development+learning both will be faster than creation and deployment on JAVA/C#.

And there are lots of API are there to define easier way to complete the project smooth and rapidly. and for content management there is no need to build any project from the scratch. just need to configure the CMS as per requirement.

And this same thing is happening in networking side as well windows server administrator and Redheat server administrator.

And nower days things are getting more worse spring developer and Asp.net devXpress developer or ASP.net mvc developer.

hope that computer engineering still be  art of solving through mathematical,logical,Automation,Communication,connectivity and storage and management problems. instead of just making configuration or writing code for some money.

Thanks for Read till the end. share your comments.

The key thing i understand about authority is that. Authority is only exist becouse in organization each and every person have responsibility of one or multiple task and the one who has most experience and who is highly paid for that has more responsibility. and to fullfill his responsibility he need total cooperation of people. and to achive that he has been assigned some level of authorities.

As far as I understand any Tech/Engineering based organization following department mostly exist in almost all of the organization and each have their responsibility.

1. Adminstrative/Management/Executive:-

this is exist because each and every organization have their own goal/aim/vision as well as purpose. and people who are members of this department are responsible for defining what must to do and where should now organization flow must go on with spirit.

2. Sales/Marketing with Account:- 

this exist because every organization need to define their market/social value to achive their goal/aim/vision and so first what should be product/services`s cost that must be defined and one which class of socity/market this product is going to make impact and how much big ipact this product could do at what level of depth. once this research has been done Sales/Marketing stratagy along with bussiness model should be defined.

3. Tech and Support / Operations.:- 

this exist because none of the vision/goal/aim or purpose could be achieved without particular technologies (If tech/engineering based organization) and this is highly special skilled job. so to define new solution strong team of technical people is most necessary thing. so this department is necessary for How or which way goal/purpose/aim or vision is going to get achieved.

so in moderan corporate organization i belief that responsibility has been distributed properly but what making me harsh is how authority has been distributed. all the authorities except recruiting staff based on specialization has been centralized and have in hand of Head of Management/Administrative/Executive department. each and every organization `s any decision that is good for organization`s progress must be passed through management. all the rules and regulation that is good for only one department and bad for other still followed by all department.

and still if any department work is not get done properly than responsible person is Head of that Particular department. I know there will be time of conflict where two department head will be against each other point. but for that management/executive/administrative department just need to be mediator to solve their conflict by defining priority and effectiveness. there is no need to keep all the authority to centralize.

and of course i am not stating here that Head of Administrative/Executive/Management should not have authority to fire or analyze all the department. he/she must have rights for firing any head person of that particular department. but why all the authorities have been centralized for MD/CEO/Executive director or Chairman.

isn't this bureaucrat-ism is hazardous for organization in sense of achieving its goal/vision/aim or purpose.
