AGENDA

• Problem Statement & Requirements

• Technology

• Use Cases

• Architecture & Design

INTRODUCTION

• Pivotal role of sales representative• Traditional IT systems for sales• Today’s customers’ expectations • Transition from IT-centric to end user-

driven operation• Computing capability to mobile sales force• Possible technologies : Mobile phone,

Laptop, PDA

COMPARING POSSIBLE SOLUTIONS

• WAP mobile phone : low cost, limited visibility and less storage

• Laptop-based software : high cost, cumbersome on-the-move, huge storage

• PDA-based software: moderate cost, extreme ease of operation, good storage

PROBLEM FORMULATION

• To capture information on the move • To seamlessly integrate captured data with

the Sales and Distribution system

• To satisfy the mobile computing needs of the sales personnel

• To design a compact, space efficient package

FUNCTIONAL REQUIREMENTS

• Customer/prospect information• Product information• Price list• Yesterday’s stock position• Order status• Customer outstanding payment• New scheme information• Order entry• Synchronization routines

NON FUNCTIONAL REQUIREMENTS

• Display should be clear and legible

• Response time should be low

• Minimal keyboard entry, providing menus for

selection

CHOICE OF TECHNOLOGY

• 2 prominent groups of PDAs : – working on Microsoft Windows CE OS – working on Palm OS

• We have selected the IPAQ for deployment and the .Net framework for development

• .Net supports PC as well as devices for deployment environment

• Scores over other environments by making available the Compact version of its .Net framework

WHAT IS .NET

• .Net is an integrated suite comprising the .Net framework, .Net products and .Net services

• .Net framework’s 3-tier platform • Base tier (Common Language Runtime):

enables interoperability & language integration

• Executable instructions compiled into EXEs and DLLs in the form of hardware-independent MSIL.

• Metadata and IL enables code to be self-describing

• JIT compilation enables code execution on any desired platform or device

COMPACT .NET FRAMEWORK

• Device emulators

• New emulator for Windows CE Pocket PC runs a true implementation of the real OS

• Enables easy development and testing of applications meant for the device

• 3 kinds of code in creating .Netcf systems:

– application code (MSIL)

– device extensions

– device profiles

• Easy implementation and invocation of Web services

USE CASES

• Accept order from customer

• Update PDA with new information

• Update orders from PDA into system

• Display and retrieval for existing customer

• Display product catalogue

• Customer contacts salesman for an order

• Validate customer’s ID and credit limit

id,SKU, quantity)

• If product valid and stock available, system

shows rate and value

• Value should not exceed credit limit

• Save order

ACCEPT ORDER FROM CUSTOMER

UPDATE PDA WITH NEW INFORMATION

• Salesman contacts operator for synchronization

• Validate salesman

• If valid, synch routine invokes corresponding Web service

• Updated rates, stocks, schemes, etc. are displayed for existing and new products

• Log off application Web server

UPDATE ORDERS FROM PDA INTO SYSTEM

• Salesman contacts operator

• Synch routine invokes corresponding Web service

• Validate customer

• Trail for all orders transferred

• No update if credit limit exceeded

• IPAQ updated for customer’s new credit limit and orders’ status

• Exit

DISPLAY AND RETRIEVAL FOR EXISTING CUSTOMERS

• Customer contacts salesman for display/retrieval

• Validate customer

• Software retrieves order and payment details for that customer

• Exit

DISPLAY PRODUCT CATALOGUE

• Salesman contacts prospective customer

• Customer specifies product of interest

• Salesman enters product id, name or SKU

• Periodic hookup with PC for upload/download

• PDA uses ActiveSync to connect to the sync

component on PC

• Sync component invokes Web Service

• Web Service synchronizes with the S & D System
