Introduction

Our company was invited by McKinsey & Company Group to share our experiences with their client, OiPAGGO.

On May 8th, 2008; we visited Oi and shared our vision on developments in the m-Payments industry.

By request of Mr. Joao Silveira, COO of Oi, we are writing this document with an external vision of the OiPAGGO situation and business model.

We focused on two main areas: Business Model and Technology.

Current Business Model:The credit system that was put together

by OiPAGGO is unique and extremely innovative. We have not seen any other m-Payments operation with a “credit line”

The system currently takes advantage only of the traditional credit users.

OiPAGGO should try to reach to a significant share of the pre-paid market.

What we think is missing….M-Bill payments Paying utilities and recurrent bills on

the go (electrical, water, phone). Bill triggers a m-Payment application

Assessment and SuggestionsAssessment of current technology

The communications channel primary used between the mobile application and the servers is  SMS which is not the best option, there have been random delays (18% transactions > 50 sec) and low throughput, it should be replaced with data channels where available.

1

Software Platform must be re-designed.Too many requests to servers for approvals (now up to 6 sms vs. 2 data request/approval)Time and completion rates are far below any reasonable standard. (55sec vs. 15sec).

2

Hardware implementation is not stable, prone to failures and not fault tolerant. It suggests weak integration

3

GPRS, EDGE, UTMS Use SMS only as fallback in case of

absence of data connection. Do not use SMS as primary option. Only

backup.

Suggestions

Use standard high end tools to develop applications (Open Architecture).

Don’t use custom made databases or programs. Use commercial tools, available in the market, easy to adapt, to change, support and to maintain.

Reengineer the hardware systems. Reengineer the software system and integration among them.

Turn key systems may speed up the process and cause less impact.

Tech Support and monitoring has too many entities responsible of the operation. (M4U-Paggo-Oi). Don’t do manual propagation of failures.

4 Concentrate all processes under one tech team. Do not use “shared responsibilities”

Unify tech operations management and trouble ticket handling process under a central authority. Automate process.

5 Adopt security standards that are being used in other markets. Ex. Encryption, tokens, etc.

Security in transactions must be enhanced.
