Witness for the knowledge


As a successor of Hiro, Kei has appointed a person in charge of financial system.
After coming to the office, she has to revise the Tax class due to the revision of the tax law, and she found a method to calculate a value that is not used at all in the class.
She tried to ask Hiro about the method, but he was assigned overseas and she cannot contact with him quickly.
Kei tried to investigate the reason of the method by herself. She looked up the documents of Tax class program comments, design documents, specifications etc, which seemed to be relevant, but there was no reference about the reason for the existence of that method.

How should we respond appropriately to problems that are not left in the document?

Hiro's colleague Joe and his boss Yoshiaki are members of the internal system department from the beginning of the financial system development, and they know to some extent the circumstances at the time.
Especially Yoshiaki knew about the rough structure of the settlement system as PM of the settlement system to a considerable extent.
Both Yoshiaki and Joe are cooperative with Kei, which makes it easy to ask questions.

Ask a third party who seems to know the circumstances.

Kei asked Yoshiaki about the necessity of the method.
Because Yoshiaki remembered that the method was made by mistake and neede to be deleted, he answered the question from Kei.
Kei was able to delete unnecessary methods according to the timing of repair.

This pattern requires Spread of knowledge. If you can ask your predecessor by Securing an emergency contact, you do not need to execute this pattern.
To make it easier for successors to implement this pattern, it is also important for third parties to create an environment in which successors can easily question. Supporting developing successor by a third party is a very effective pattern to create such an environment.Through Reunion for oldmembers, many third parties become Witnesses for the knowledge and the range of knowledge gained by this pattern will widen. Also, since it is not enough with sighting information alone, it is important to conduct Neighboring excavation together and obtain confirmation.
