Inside/Outside

You look at a thing and you want to describe and understand it. There are many ways, but we can broadly define two principal ways.

Outside View Point (OVP):
Everything has external view to its environment. When a thing is described with less focus on its internals, that is OVP.

Inside View Point (IVP):
Everything is internally composed of other things. When a thing is described with more focus on its internals and less focus on its externals, that is IVP.

Also, internals of a thing are things too. So, internal things have their own IVP and OVP.
Here are some examples. Note that decision, if a statement is IVP or OVP, is subjective.
Following are my views on few statements as a layman car user, based on my intellect and knowledge.

A car has a red color: OVP
A car has an MPFI engine and is 4WD vehicle: IVP
A car has engine made with special aluminum alloy: IVP
A car is saleable thing: OVP
A car needs maintenance every 10000 kms: OVP
A car turns left when you turn steering wheel counter clockwise: OVP
A car needs proper suspension: IVP
A car must not jump too much during ride on normal road: OVP
A car has factory-installed locking differentials use a computer-controlled multi-plate clutch or viscous coupling unit to join the shafts: IVP

It is very important that IVP and OVP are understood enough to clearly describe a thing. How much details are enough for IVP or OVP is usually context sensitive. These two views are important because you can always use them fruitfully in some way. They are more important because our brains are programmed to use them.

Usually, we tend to use either IVP or OVP. Once we are biased about one, we become blind toward the other. Each thing is a unity in itself even if externally only few characteristics are manifested and internally it is made of multiple things. Being blind towards either IVP or OVP renders description of a thing incomplete.

Most of the times, thing to be described, is not trivial. So it is very normal to further partition within both IVP and OVP. It is normal to create team, with each person focusing on subset of such partitions. For big thing, there may be need for team of team of teams. Note that each partition has its own IVP and OVP.

IVP focuses more onto these: analysis, structure, architecture, design, utility, technicality, how & why
IVP usually have more amounts of details. To grasp IVP, you need good left brain.
OVP focuses more onto these: intuition, judgment, aesthetics, surface view, what & where
OVP usually have comparatively less amount of details. To grasp OVP, you need good right brain.

In nutshell, you need to know enough of IVP and OVP of a thing to ‘know’ it. That will be more complete knowledge!
