Why to use custom software instead of third-party software mix

Ability to use data throught applications

Problems with data and processes you can run into when using separate systems for partial activities instead of one global custom system.

A custom software keeps all data and processes under one roof instead of a mix of third-party software.

Duplicated data (overlapping data, different formats).
Data and processes cannot be linked together.
Transaction costs: imports and exports, data inconsistencies, different formats, it is not under control and existing solutions cannot be bent to fit.
Licence fees and duplicated costs (for parts present in more software), you pay even for features you do not need.

The theme is cooking an oxtail soup (without an oxtail).

Introduction
- the boss in a chef’s hat
- he imagines what to cook: an oxtail broth in a big pot over a small fire
- he looks into the cupboard, but there are only small saucepans
Duplicated data, different formats
- he opens a cookbook with imperial units and spoons/cups/…, but the scale shows kg
- several baskets and crates of vegetables, things jump out of them, some are duplicated (carrots, potatoes), they pile up
Duplicated costs, licences for parts which are not needed
- the pile is full of leftovers that will not be used (the vegetables go bad, a chick hatches from an egg)
- the boss wants an oxtail for the soup, he grabs a cow by the tail with a cleaver, the cow looks at him: “Seriously?”
Data and processes cannot be linked
- a big stove with many small saucepans
- everything needs to be salted
- everything needs to be stirred (but one by one)
- before he stirs the last one, the first one boils over or starts smoking
Transaction costs, the software cannot be bent to fit
- many pots, things are poured all the time from one to another, from the third one back to the first
- he has to serve a little bit from every pot onto the plate
