Arrayformula for the Data Validation and if function - arrays

Question

Action item tab:
Column A - Score - is based on calculations from the columns F-N
I want to assess the score according to the following range and assign the task in column B from a drop down menu.
Minor update 89-50
Localize 49-20
Major update 49-20
Merge 49-20
No action item 90-100
Redirect 0-19
It is important to keep the dropdown menu since the data is going to be checked manually and the status might be changed.
So generally speaking, I want to implement 2 steps:
Automatically to range the data and assign the status
To have the possibility to change the status manually.
I tried to implement it through Data Validation and simply failed.

Answer 1

First of all, three of your ranges are conflicting, it will still work but will always get the first one which is "Localize". You should update the ranges for Localize, Major update and Merge so they don't have conflicting ranges.
Conflict:
Formula (A4):
=ifs(and(A4 < 90, A4 >= 50), "Minor update",
and(A4 < 50, A4 >= 20), "Localize",
and(A4 < 50, A4 >= 20), "Major update",
and(A4 < 50, A4 >= 20), "Merge",
and(A4 <= 100, A4 >= 90), "No action item",
and(A4 < 20, A4 >= 0), "Redirect")
Just drag the formula onto the cells below (e.g A5-A9). I am not using Arrayformula as it will fail if you modify a cell within its range.
Output:
Modifying F5 and G5 (Extracted data) to 0:
Note:
You can have formula on top of your Data Validations
I modified your Data Validations for column B into from =Legend!$A$2:$B$7 to =Legend!$A$2:$A$7 since we only need the action items, not the range.
You can still manually change your column B values BUT it won't automatically update ever again after manually changing it unless you copy the formula again to that cell and it will overwrite your manual input and go back to automatically updating based on the column F-N values.
These changes were already applied to your sheet, kindly check if it meets your expected output.
