You have to climb up the Systems Staircase.

I get many queries from both fresh and experienced software engineers & other graduates who immediately want to jump into the ERP area. Just like
many graduates who want to join MBA B-schools straight from their
graduate college without having atleast a few years of real world
experience.

My advice to them is to have a look at the Systems Staircase.

ERP Systems are at much higher levels as compared to the other
systems at the lower levels in terms of business scope and technical complexity.

You cannot jump intermediate steps.

You have to climb the Systems Staircase, step by step; slowly but surely.

At every level.

Learning the lessons assimilated at lower levels and then only move upwards.

There are no shortcuts.

Also, many young engineers express dismay at having to work with
manual non-automated systems.

Remember, this is WALMART's secret.

Making all their software engineers work on existing WALMART systems
(automated or manual) as end-users before getting them to start
designing new systems.

To get a valuable end-user perspective of the operations.
