As per 2025 data, there are already close to 19 billion devices in the world. Furthermore, the number of devices is growing steadily at 13% and the number will likely go beyond 40 billion by 2030. IoT has without a doubt transformed our current world, transforming distinct industries around the globe. It impacts our routine processes in ways we cannot even imagine. Starting from aiding us in determining how to travel, how we purchase products, to high stake business decisions, the application of IoT is everywhere. IoT is a mixture of numerous devices that can be anything from simple wearables and industrial machinery to costly medical appliances. It involves diverse technologies like IoT actuators, sensors, cloud computing, high-speed transfer of data, RF communication, etc. In order to implement IoT technology, it is necessary to have an in-depth conceptual understanding of IoT design methodology.
Understanding IoT Design Methodology- Overview
Developing IoT platforms is a fully technical and complex task involving tricky challenges. It is essential to establish seamless connections between various systems to ensure smooth data exchange. However, for every component and facet, IoT developers can choose between various options. To make the right choice, IoT engineers must keep the design aligned with their products and objectives. In this blog, we will mainly concentrate on general design methodology. It will be true regardless of your product, service, or language. The overall design of your IoT ecosystem can then further impact your design time, testing time, maintenance time, complexity, and interoperability. Thus, it is imperative to have an IoT design methodology absolutely perfect. Explore this blog to learn more.
Methodology Steps
The basic design methodology for an IoT ecosystem is explained in-depth in the following points-
Purpose And Requirement
Determining the overall purpose and requirements of the system is the very first step. This step involves defining the behavior, requirements, and the needs of the platform. The requirements are listed as follows:
- User interface requirements
- Data collection requirements
- Data analysis requirements
- Security standards
- System management prerequisites.
Procedure Detail
This step converts the determined requirements and goals into precise application areas of the IoT platform. It describes how distinct components interact, what processes will be performed, and the precise conditions under which they will be performed. Every procedure showcases a proper functional flow, enabling developers to comprehend system behavior before proceeding to the modeling phase.
Domain Model Specification
The third step in the IoT design methodology is the domain model specification. The domain model showcases the main entities, concepts, and objects in the IoT system domain which will be generated. The domain model defines the object properties and their connections. It is not dependent on any technology or platform.
The system designers can understand the IoT domain for which the platform is designed through domain models.
Information Model Specification
In this step, the overall information model is determined. Essentially, the information model defines the complete information architecture of IoT platforms, including virtual entity properties, relationships, and other structures. These models don’t go into great detail about the storage and display of data.
Service Specification
The services in the IoT ecosystem including input/outputs, service types, schedules, endpoints, effects, preconditions, etc., are defined in this step by service specifications.
Such services either retrieve the present value, change the state, or allocate values. The mode service is a kind of RESTful web service that might be utilized for GET Request or PUT Request. The mode is either retrieved from the database or updated to the database. The state service is a kind of RESTful web service that enables users to receive the present light state (GET Request) or set the status of light appliance as off or on (PUT Request).
This status is either retrieved or updated in the status database. On the device, the controller service works as a native service.

IoT Specification
In this state of IoT design methodology, IoT developers must work toward defining the IoT levels of the system. Five distinct deployment levels are utilized depending on diverse circumstances:
- IoT Level 1
- IoT Level 2
- IoT Level 3
- IoT Level 4
- IoT Level 5
Functional View Specification
The functions of IoT systems are classified into distinct functional groups as per the functional groups. Each functional group offers details related to the functionalities and ideas for interaction in the domain model.
A functional view includes the below-mentioned functional groups:
- Management
- Application
- Security
- Communication
- Device
- Services
Operational View Specification
In the IoT design methodology, this step is related to determining the operational view specifications. The operation and deployment of IoT platforms are defined. This involves options for service storage, hosting, application hosting, device hosting, storage, etc.
Component and Device Integration-
This step includes incorporating component designs and devices. It includes an LDR sensor, IoT actuators, and a microcomputer.
Application Building-
This is the final phase in the IoT design methodology. Its purpose is to build an IoT application. The application has the controls for light (on or off) or mode (auto-on or auto-off).
Importance Of IoT Design
