Active Threat Response System For A Security Company

ABOUT THE CLIENT

After extensive years of experience in the law enforcement field, our clients came up with a vision to change how threats are perceived which can determine how they can be handled. After witnessing various high risk situations, the founders of the company are on a mission to save lives through an active threat response system which can create proactive response plans by harnessing the latest technologies. The founder and CEO of the company who had witnessed various high-risk situations throughout his career which gave him the expertise and the experience necessary to change how public safety is perceived.

The Problem

The idea was to create an app to respond to crisis situations and once the requirements were set in place and the team finally introduced to the client, it was time to get cracking. Primarily, the technologies for the project were finalised along with the designs for both the mobile and web versions of the app.

The client wanted to use Flutter for the mobile version because of its cross-platform functionalities and its out of the box compatibility. Even though Flutter was the desired tech stack of choice, our developers suggested that we go forward with React for its higher efficiency in handling dependencies and the excellent cross-platform support that it offers. The client has also thought of using the Aqueduct Framework built using DART as the backend but due to few setbacks, like implementing the map function and its overall compatibility, we decided to go with Python instead. Python and Django frameworks also provide good support for geo-JSON data formats along with sockets and admin dashboard making it the apt choice.

We initially started the development work for the mobile version of the application that has in total three workflows to give the app a truly holistic and well-rounded experience to take on all aspects of risk management. The workflow for the mobile app was to integrate the following phases:

Student Flow: In the student flow, the user can create an incident and provide the details in reports which would contain information about the suspects and potential injuries. The intended user base was to consist of students, teachers and staff wherein the victims can mobile which followed a two-step process to create the event: the suspect report where the user can sketch the suspect using the app and the injury report which basically tells the injured person location.

Police flow: Generally, this is bifurcated based on the locations of any event that is triggered. Using this functionality and the suspect description given by the student an automated call is sent to the frontline. This information will be created in the form of an event and legal enforcement can easily access the location using this data.

Medical Flow: The medical flow is divided based on the locations; if any event is triggered based on the report given by the user, this information will reach the EMS team in an automated fashion and they can choose to join any event without any approval and save the victim.

Once the work on the mobile application was done, the next step was to create a web app for admin usage. The web app was designed to be used by admins to gather organisational information like name, users, description, geo-fence, perimeter points, command post, user information and along with an added functionality to manage the CRUD operations of data. The team needed to refactor in a major part of the code which was handled via the help of Redis and Pub/Sub was integrated to handle real time updates along with an option for multiple event workflows. An opps centre was also implemented and we are currently working on a feature to implement live-location tracking to streamline the process of connecting victims to frontline workers.

TEAM ON CALL

After discussing with the client, we put together a team of five who would take the project forward. The team consisted of two Frontend developers who would each handle the mobile and web versions and a Backend developer spearheaded by a Team Lead to oversee the progress on the project. An account manager was additionally roped to handle all interactions with the client and ensure that the development was flowing smoothly.

The client wanted us to develop a real-time active threat management system.

The app was to connect law enforcement and medical responders with citizens instantaneously during a crisis.

The goal was to develop mobile and iPad apps for end-users along with a web version for admin use.

The crisis management tool was designed to automate key tasks by providing first responders with a live overview of the entire event.

OUR APPROACH

Strategy Analysis Planning UI/UX Development Testing Delivery

Strategy

In an effort to leverage high-end technology to improve the processes of a security service company, we partnered with the company on an engagement based on the T&M model. The collaboration which started seven months ago is still ongoing.

Analysis Planning

We decided to go with React for the Frontend which we implemented with Python working in tandem with Django for the Backend for its enhanced support for geo-JSON formats, which was the necessity in this scenario.

UI/UX

As the application was built from scratch, the design team curated individual screens with apt themes while target audience in mind.

Development

The development phase of the active threat management system resulted in the creation of an app that can connect frontline workers with victims during a crisis which required the implementation of elements like a suspect sketching feature, location sharing, ability to file reports, etc.

Testing

The team followed a TDD approach system for testing wherein they wrote separate use cases and tested them individually. The technologies for this process was Firebase for the mobile app while the team thought it would be apt to implement an Azure pipeline using Cypress for web.

Delivery

The application is all set to be launched later this year and the progress on the project is still ongoing with the team working collaboratively with the partner to ensure that the product reaches perfection.

OVERCOMING CHALLENGES

Overcoming hurdles is an important part of effective project management and our team rose to the occasion by navigating through any speed bumps that came their way. A major challenge that was faced was in setting up AppCenter for producing builds and other DevOps operations. The team had decided to use Azure but since they were new to the framework, they had to conduct extensive research to get the app up and running. Since we were using Azure services for development(i.e Pub/Sub), it made more sense for the client to use the Microsoft ecosystem for end-to-end production development and deployment. One of the major challenges faced during the deployment of AppCenter is because it has a short live authentication token which breaks the connectivity with Apple App store frequently. There was trouble setting up Pub/Sub services as there is limited documentation and it is also very unstable. The team who did not receive the required help from Microsoft, resorted to moving the state from Azure Gov to Azure global while also implementing Redis which they had to build from scratch.

In bird's eye view

The TDD approach was adopted for testing.
The app was integrated with a Pub/Sub setup to handle real-time updates.
Automation testing was conducted for the web version using Cypress.

DEVELOPMENT

FINAL IMPRESSION

It was our previously successful engagement with the client that brought them to our doors again, and the team were determined to give it their best shot to create a perfect product. The client is quite happy with how the progress on the project is coming along and has commended the team on their ability to meet deadlines on time and how they had handled any challenges that came their way during the development process. We are excited for the launch of the product which is set to be later this year.
