Hi There,

Whether you wish to pursue a Management course after Graduating is completely your choice and as far as it being a good option is again completely in your hands. It is how you use the degree to your advantage.

These days it is a trend that every Graduate must pursue an MBA program. Not only a trend, but even companies insists on hiring an MBA graduate.
But please note that Management is for those Graduates, who do not have much of a standing with their degree. I mean their degree by itself will not be able to help them get a better prospect.
I do not see this issue with you as such. Your degree in Engineering, will help you get better prospects

Also I believe that Managers need to know their job profile well, before they get into managing a team. Thus MBA after few years of work experience is a better option. With few years of experience, one knows their potentials and knows their job well to be able to guide a team.
In your case, please note that, once you pursue an MBA, you move from a technical background to a non technical background. But I would advise, that before you move into the non technical aspect, why not get a hang of the technical market first.

Lastly, a degree is just a means for one to get into the job market. The knowledge one gains out of the degree, when used practically defines the scope and use of that degree per-say.

Cutting the long story short, I would firmly advise, get into a technical job, experience the market and their demands and then to get a better prospect if you think MBA is an option, go ahead and study an MBA program.

Hope this helps.

wISH YOU GOOD LUCK...
