What are type $1$ decisions?

A$.$ A type $1$ decision is consequential and irreversible or nearly irreversible $-$ one$-$way doors $-$ and these decisions must be made methodically, carefully, slowly, with great deliberation and consultation. If you walk through and don't like what you see on the other side, you can't get back to where you were before.

B$.$ A type $1$ decision is changeable or reversible, they're two$-$way doors. If you've made a sub$-$optimal decision, you don't have to live with the consequences for that long; you can reopen the door and go back through.

C$.$ A type $1$ decision is basic or strategic in its decision, it relates to policy matters and usually involves large investments or expenditure of funds.

D$.$ A type $1$ decision is one that is neither urgent nor important.
