I think that many people use the word of "horizontal expansion" easily.
"Horizontal expansion" is to expand the existing technologies or know-hows to another objects.
The motivation of "horizontal expansion" is, honestly speaking,
a hope to "take it easy", "bargain for it", and "finish it quickly"
and to realize them.

"Horizontal expansion" is also attractive for executive officers.
Above all, it is a magic word that just one investment can make a lot of acceptances of order after that.
However, "horizontal expansion" will not work well in many cases.
For not only heterogeneous business(goods and services), but also homogeneous, it is not easy.
As far as "horizontal expansion", to start making scratch might be cheaper.
