NICHE is not a Marketing jargon

Niche marketing is positioning your products in your consumer's mind. It is finding that spot or niche which makes your product uniquely different from your competitor's.  Any good book on marketing will provide you details of niche marketing

When Beatles broke onto the music seen in the 60s, it was era of solo singers; Cliff Richards, Harry Belafonte & others. But the Beatles captured the minds, hearts and ultimately the purse of the public by offering something different & unique- four of them singing together. Down the years they were followed by others like Rolling Stones, ABBA, Bee Gees etc, but it was the Beatles who unknowingly created the niche in the public's mind!!

Now let us take it a step and extend niche marketing to your career.

In your present position, have you found that niche which makes you indispensable to your organisation if not irreplaceable? However, don't make yourself so indispensable, that you can’t progress in your career 'coz apart from you nobody can do your job! Think in terms of grooming someone, who can take over from you when you move UP, not sideways. Make sure to keep things under control, so that you are not outsmarted by the person u r grooming!!
