Lifecycle Model

Abstract
The data warehouse has played a very important role in the transformation of the
state owned telecommunications company in South Africa. This transformation
process concentrated firstly on targets set by government during the exclusivity
period and secondly, on the preparation for competition. A new Double Wave
Data Warehouse lifecycle model was developed and followed to fulfil the
immediate need for information through the building of a DW and BI solution in
the company. It consisted of two iterations for the development of a DW and BI
solution. Wave one concentrated on the rapid implementation of a Business
Critical Information Solution. In this regard management information on bad
debts and debtors days were considered as Business Critical Information
Solution needs. Wave 2 concentrated on modelling the ongoing requirement into
a permanent dimensional model.
Keywords: lifecycle model, data warehousing, telecommunications BI, business
strategy, business intelligence strategy, developing countries.
1 Introduction
South Africa as a developing country has, since 1994, gone through a process of
privatisation of some of the state departments. The Department of Post and
Telecommunications was one of those departments. In order to obtain exclusive
rights, for a limited period, as the sole landline provider, government has set
several targets for the new telecommunications company.
The exclusivity period was to last for five years, until May 2002, but could be
extended to six years, if the telecommunication operator met network rollout and
service targets. The rollout targets included doubling its subscriber access lines
