Does your company have a legacy application which requires to be re-engineered?

The legacy application needs to be remodeled keeping in mind the pain-points like loading time of an application, battery consumption, size of the application and security pitfalls. While revamping an application, one needs to keep in mind as to which subset functionalities need to be added by understanding the existing application. The latest updates and strategies need to be adopted which suffice the requirements with a minimal impact on the ongoing activities.

Are you interested in knowing how Cygnet Infotech works during the re-engineering of a mobile application?

Let’s zero down to understand how we work, during the initial stage of product re-engineering.

Requirement Elicitation is like a Compiler

Complier is a program that coverts all the instructions in one go into computer understandable format. In the Requirement Elicitation, the requirements are gathered from the necessary resources which help us look at the bigger picture of the mobile application.

To know what all is required for your mobile application is very important. The business analyst should keep in mind the target audience and then gather the requirements by

Studying the Current Application

The most crucial step one is - Studying and analyzing the current application. In-depth analysis leads to identifying the actual need of new feature, which functionalities should be removed and which functionalities should be altered or extended.

Identifying the Stakeholders and Actors

While gathering the requirements, it is very necessary to identify the stakeholders and actors. Participatory planning requires the involvement of the concerned actors and stakeholders. While identifying, one gets to know as to how the stakeholders are affected by the outcome, negatively or positively.

Identifying the key Functionalities

It becomes significant to identify the key functionalities which needs to be affixed helping you to look at the application from all the horizons.

Eliciting the Requirements through various techniques

Observation:

In this stage, the requirements are gathered through observing the process of the current system. Here the Business Analyst participates in the actual work process to understand and capture requirements for your custom mobile app development.

Questionnaire and Interviews:

Questionnaire is a list of relevant questions which can be electronic or paper based and can be used in interviews to gather information from clients, stakeholders or the targeted audience.

Reference Sites:

In this step, the requirements are accumulated by referring the existing sites which might be similar or approximately close to the new idea that has to be implemented in the new application. This will help in knowing the functionalities as well as its parameters.

Technical Analysis is like an Interpreter

Interpreter is a program that converts line by line instructions into computer understandable format. The requirements that are gathered in the requirement elicitation phase are analyzed line by line in the technical analysis.

The information in the technical analysis phase can be analyzed as following :

Nonfunctional HTML Prototyping

Prototyping is to create a model of the system after understanding of the requirements. Prototyping is a part of analysis phase which depicts how the application will look, by giving the client the actual feel of the application.

Performing Gap Analysis of the Mobile Application

Gap Analysis is a method of assessing the steps which should be taken while moving from old application to the new application. While re-engineering of the mobile application we consider:

Adding new functionalities not present in the old application

Removing old functionalities not needed in the current application

Necessary functionalities present in the old application but required to be altered or extended in the new application i.e. re-engineering.

Document Analysis

Effective Documentation is the core which comprises of comprehensive and highly analyzed information. From this analysis, the correctness and the completeness of the requirements can be validated.

It becomes very necessary for the developer to understand the full spectrum of what the client is expecting from the re-engineering of the mobile application
