Answer to question 1 depends highly on the business strategy and objectives defined by the management team. Typically in terms of reporting, you see following reporting / analysis:
you would see sales reporting and monitoring on a Circle / Ward number. Typically the sales would be split by product type and plan type. You would then measure this performance against business targets, previous months and same month previous year to see how things have changed and whether it is in line with your expectations or not. If the Organization is evolved in analytics, they might assign a customer lifetime value to each customer or even have a segmentation in place. If this is the case, the telecom player would also measure the acquisition against customer life time value.
The analytics at this stage would mostly be concerned with finding the right customers, the right distributors and making sure every one works on the right margins. There can be a lot of analysis around target setting and incentives as well.
At this stage, you would mainly be concerned with usage of your products. So, you would look at things like monthly spend, add on packs used, type of plan a customer is on and what are some additional plans, he might be interested in (Cross-sell). You can also look at up-selling the existing products to your customers.
This would matter only on post-paid connections. The reporting would be interested in roll rates, flow rates and default rates. Making sure that the calling intensity to various types of customers is in line with the strategy.
From analytics perspective, you would primarily be interested in predicting risk of customers and best way to increase collections from these customers over time.
There are a few other problems, which might be of interest. For example, customer churn is one of the biggest challenge for most of the telecom service providers in India. Some providers also monitor fraud closely.
Hope this helps
