title: Using the Sequential Processes in crewAI
|
|
description: A comprehensive guide to utilizing the sequential processe for task execution in crewAI projects.
|
|

|

|
|
## Introduction
|
|
CrewAI offers a flexible framework for executing tasks in a structured manner, supporting both sequential and hierarchical processes. This guide outlines how to effectively implement these processes to ensure efficient task execution and project completion.
|
|
|
|
## Sequential Process Overview
|
|
The sequential process ensures tasks are executed one after the other, following a linear progression. This approach is ideal for projects requiring tasks to be completed in a specific order.
|
|
|
|
### Key Features
|
|
- **Linear Task Flow**: Ensures orderly progression by handling tasks in a predetermined sequence.
|
|
- **Simplicity**: Best suited for projects with clear, step-by-step tasks.
|
|
- **Easy Monitoring**: Facilitates easy tracking of task completion and project progress.
|
|
|
|
|
|
## Implementing the Sequential Process
|
|
Assemble your crew and define tasks in the order they need to be executed.
|
|
|
|
```python
|
|
from crewai import Crew, Process, Agent, Task
|
|
|
|
# Define your agents
|
|
researcher = Agent(
|
|
role='Researcher',
|
|
goal='Conduct foundational research',
|
|
backstory='An experienced researcher with a passion for uncovering insights'
|
|
)
|
|
analyst = Agent(
|
|
role='Data Analyst',
|
|
goal='Analyze research findings',
|
|
backstory='A meticulous analyst with a knack for uncovering patterns'
|
|
)
|
|
writer = Agent(
|
|
role='Writer',
|
|
goal='Draft the final report',
|
|
backstory='A skilled writer with a talent for crafting compelling narratives'
|
|
)
|
|
|
|
# Define the tasks in sequence
|
|
research_task = Task(description='Gather relevant data...', agent=researcher)
|
|
analysis_task = Task(description='Analyze the data...', agent=analyst)
|
|
writing_task = Task(description='Compose the report...', agent=writer)
|
|
|
|
# Form the crew with a sequential process
|
|
report_crew = Crew(
|
|
agents=[researcher, analyst, writer],
|
|
tasks=[research_task, analysis_task, writing_task],
|
|
process=Process.sequential
|
|
)
|
|
```
|
|
|
|
### Workflow in Action
|
|
1. **Initial Task**: In a sequential process, the first agent completes their task and signals completion.
|
|
2. **Subsequent Tasks**: Agents pick up their tasks based on the process type, with outcomes of preceding tasks or manager directives guiding their execution.
|
|
3. **Completion**: The process concludes once the final task is executed, leading to project completion.
|
|
|
|
## Conclusion
|
|
The sequential process in CrewAI provides a clear, straightforward path for task execution. It's particularly suited for projects requiring a logical progression of tasks, ensuring each step is completed before the next begins, thereby facilitating a cohesive final product.
