The history of an organization must be true and accurate. If you are to work in an organization which has a positive culture and shared vision it is essential to know where you have come from, the past influences the future. While perspectives exist and everyone will view events with their own bias and memory – an objective truth exists.
To capture this truth, deal in fact. Avoid being too specific when people are concerned. For example, an issue that is potentially contentious would be an assignment of a project manager for a desirable contract. Descriptions of this event should record simply decision was made, by whoever was involved, considering the factors that were used. It should avoid recording contentious things that the detailed comparisons between people. It may be important at the time but in time all that will matter will be the decision not all of the reasons.
When service, technical or business issues are concerned be more specific but never deal in feelings and opinion, these areas are often supported by facts so capture the ones that mattered at the time.
In the ideal world, we must strive to achieve this e result of this attention to important detail will be a clear and simple history. Opinions and feelings will be remembered but the truth of the shared history will be captured such that it does not need to be revisited and it can help inform your approach to the often muddy and complicated present.
Remember this truth – the past is no indicator of the future – but it can feel that way.
And never rewrite history – someone will notice and it doesn’t make you look good after all it is lying.
