The question for my assignment is - What are the key management information requirements?

I have answered the following:

Management accounting information is used to support the decision-making requirements of users within the organisation and may include both qualitative and quantitative information. Management accounting information should comply with a various number of things including accuracy, completeness, verifiability, objectivity, timeliness, comparability, reliability, understandability and relevance if it is to be useful in planning, control and decision-making. The information system used to gather the required data has to set up correctly so that any information produced and then used for decision-making purposes is always complete.

Management may consider the following in regards to any key information received: - Information used in reports and written or verbal advice has to be complete and free of any omissions - Reports should detail information favorable to the views & position taken - but also include opposing arguments. - Information must be verifiable - they must be able to demonstrate that information is true and accurate. - Information must be relevant - a good idea to sort useful, relevant information from irrelevant information. - Information has to be appropriate for the purpose - decide if the information is of real use to help meet goals.

However my tutor has said "Please consider reasons and caused for variance also"

Can someone please assist me with what I need to cover as per the tutors comments?

Thanks
