Challenges of e-mail

http://danieltenner.com/posts/0012-google-wave.html

• A Wave is shared• A Wave is both conversation and

document• A Wave is live• A Wave can be extended to provide

business context

Wave is a hosted conversation

By design solves most of e-mail’s problems


Wave in organisationsNo emails back and forth.

ClarityA lot of processes in organisations can

leverage from the use of Wave. A lot of unstructured processes cannot be

fitted into a box. 80/20 ruleOne place to have communicationPlatform for developing applications

Operational Transformation

• Any changes to the shared object is described as an operationo e.g. insert character "a" at position x

• As long as there is a function transform() with the following behaviour, it is always possible to have all the clients come to an convergent state.o S = Server Operation

C = Client OperationS' = Transformed Server OperationC' = Transformed Client Operation

(S', C') = transform(S, C)where

C'⋅S = S'⋅C• Client and server must have the same transform() function
