Symptoms

There are couple of frequent questions when it comes to K2 worklist functionality an flags displayed in worklist:

1) Does K2 take into account working hours and holidays configured in K2 when doing calculations for flag color?

2) Is it possible to sortfilter tasks using flag's filter?
 

Diagnoses

(1) Does K2 take into account working hours and holidays configured in K2 when doing calculations for flag color?

The flag colors (in the Status column on K2 Workspace's worklist) are calculated as follows:
Expected_Completion_Date = Activity.StartDate Activity.ExpectedDuration
If Current_Date_Time <= Expected_Completion_Date Then Flag_Color = Green
If Expected_Completion_Date < Current_Date_Time <= Expected_Completion_Date 24hrs Then Flag_Color = Yellow
If Current_Date_Time > Expected_Completion_Date 24hrs Then Flag_Color = Red

We are not taking into account holidays/working hours at the moment. There is an existing feature request for this functionality (internal TFS item ID 640134)

2) Is it possible to sortfilter tasks using flag's filter?

No it is not possible at the moment, and there is an existing feature request for this functionality (internal TFS item ID 640136)
 

Resolution

Currently we do not take into account working hours for worklist flag colors calculation and it is not possible to filer by flag color. There are existing feature requests for this and clients interested in this functionality encouraged to log K2 support tickets to link them with existing feature request/check feature request status.
