A.6.3.RT.OE:8 - Common Anti-Patterns and How to Avoid Them

Failure in these situations	Consequence	Repair
Preserve all labels but hide a shared part	The user cannot combine the relevant relations.	Keep the common part recognizable across the needed groupings.
Remove grouping to make the expression shorter	A different operation or continuation becomes permitted.	Restore the scheme’s scope or grouping rule.
Align signs without a common reference	The arrangement suggests a comparison or timing relation that does not hold.	Supply the relevant origin, scale, units or temporal reference.
Treat a conclusion suggested by a drawing as source-given	The claim loses the argument needed for its use.	Perform the subject inference and retain its premises.
Change notation when the subject operation is missing	A new form leaves the same construction unavailable.	Obtain the missing Method contribution and then prepare its expression.
Infer fluent performance from a calculated arrangement	A prepared sequence is mistaken for acquired capability.	Assess execution or learning when that result is required.
