Part 1. Important Things to Consider Before You Start Making a Sequence Diagram

A list of a few things you must keep in mind when creating a sequence diagram is attached below.

1. Select the Right Level of Abstraction

First of all, consider how much information or details you want to add to the diagram. Try focusing on a high-level overview of the system, considering your audience and purpose. Different parts of the diagram can be associated with different levels of abstraction, but don’t forget to ensure that they are coherent and consistent. Always avoid unnecessary complexity.

2. Highlight Lifelines & Actors

The objects present in the system that communicate with each other are known as lifelines. They include instances, components, and classes. On the other hand, external entities that send and receive messages from a system are called actors. They include systems, devices, and users. Stereotypes, names, or symbols can be used to represent lifelines and actors on your diagram.

3. Defines Messages & Interactions

Defining interactions and messages is, in fact, the core of your sequence diagram. They occur between lifelines and actors.

A message is a command or information exchanged like signals, events, or method calls. Whereas an interaction is a pattern or sequence of messages that achieve a specific output like fragments, alternatives, and loops.

Horizontal dashed or solid arrows are used to denote messages, whereas guards, frames, or boxes denote interactions.

4. Use Appropriate Notations & Layout

Your sequence diagram should always be easy to read. For this, you must follow best practices for layouts and notations. The diagram’s layout should be consistent and logical. Always avoid conflicting or ambiguous elements; instead, use standard UML syntax and symbols for notation. You can also use comments or notes to improve the readability.

5. Refine the Diagram

It is time to review your sequence diagram and ensure that it meets all the above requirements. Make sure it has all the information you need, and everything is well-organized. You can use different methods, like simulation, testing, or peer review, to validate your diagram. The best thing is to use a dedicated tool, like Lucidchart, to create this diagram.
