2. Scope of Work

Being in the hospitality industry, the client is well aware of the changing trends of tourists and travelers for leisure and business. Changing lifestyles of travelers often leave them with very little time for exploring options for shopping or picking the best places to stay within a budget. The client wanted to offer people coming to Zimbabwe and citizens traveling across the country an assortment of services at the tip of their fingers.

The aim was to provide users an array of services through a single app helping eliminate the need for downloading individual apps. The intent was to upgrade the existing app with a load of features that will have users hooked on to the app for all purposes, in all situations. There was the need to upgrade the app in a way that users can avail all types of services easily and in a hassle-free way even as the stressful times of the global pandemic continues.

3. Solution Overview

The existing app RTG Gateway (that we had built earlier) was rebranded as Gateway Stream with the addition of some of the most sought-after in-app features. We included 3 crucial features, that is, online shopping, music and insurance for the maximum benefit of users. We have modified the present app such that users can find the best hotels and homestay, holiday packages, make ride bookings, choosing the best dishes at some of the most well-know restaurants, order them online, and shop for items and groceries online.

There are also options to help users find on-going events and venues to host them, buy insurance and even bid for the hotel package deals for the best buy. While the insurance feature and the music are among the later additions that we made, we added the e-commerce portal to facilitate online buying of items and groceries in the pandemic-induced situation.

The project involved complex backend work which was made easy using the Agile-Hybrid model of execution. Under the Agile-Scrum Methodology, work was broken down into smaller segments and neatly assigned to members with clear parameters. Each developer/designer knew her/his responsibilities and was in constant touch with other team members through common communication channels. This facilitated seamless progress with complete visibility of work item giving the project manager bird’s-eye-view all through the project cycle. Any backlog or issues were promptly dealt with by members working comfortably from their individual spaces as part of the Hybrid Team.
