[Shah Alam Kabir Pramanik]

Diagonal Combination:
It means integration of a main activity or process with ancillary activities and services.
For instance, a newspaper company may integrate with Transport Company to ensure quick delivery of the newspaper to different parts of the country.
Or an automobile plant may combine with a power generating unit. Thus, diversification of activities is diagonal. The purpose of diagonal integration is to ensure smooth and timely availability of ancillary services which are essential for the continuous working of the main units.
