Situation: Gas company, 400k customers, B2B and B2C. Going for application to replace current billing system which is 20 years old.
Analysis phase just started, Key sponsor wants to complete the project within a year and Supplier is ready to propose implementation time 1 year.
My personal experience - only B2B probably yes within year, but full scale project to include also B2C will take at least 2 years. In scope also development of customer.
Your experience regarding timescale for billing system replacement projects?
Any suggestion how to deal with Key Sponsor?
One of option I'm thinking of is to refuse continue manage the project? Saving Changes...
