And also: Generally used for connecting the work of:
Software Engineering PRODUCT DELIVERY (Building Code in response to user requirements, defect fixing, and New Feature Requests.
Software Project Management: Addresses the business concerns of Product Delivery: budget, schedule, risk management, resource planning, quality plan.

In project management: We have the Project Management Triangle:

You can have 2 of these but give up the third one:

Better
Faster (development time)
Cheaper (development cost, not product cost)
Additional Reference Material:

GitLab CI/CD is an integrated part of the GitLab platform that allows developers to run CI/CD pipelines against their code.
It automatically tests, builds, and deploys code changes to ensure only high-quality and functional code is merged and released [3]. GitLab CI/CD offers several features, including customizable pipelines, parallel execution of jobs, and support for Docker and Kubernetes [3].
GitHub Actions, on the other hand, is a CI/CD tool integrated with GitHub that automates software development workflows directly within a repository [1]. It builds, tests, and deploys code automatically, responding to events such as pull requests and issues [2]. GitHub Actions supports a wide range of platforms, languages, and clouds, and allows developers to share their workflows with the community or access pre-built CI/CD workflows from the GitHub Marketplace [2].
Both GitLab CI/CD and GitHub Actions streamline the software development process by automating critical tasks, reducing release cycles, and improving the quality and reliability of software releases [1][3].

Lab Activity: Git Issues and GIT Actions

Lab Lesson Workbook: Git Repository for AI Product Development

Introduction
This lab workbook will guide you through the process of
setting up a Git repository,
managing Git issues, and
performing Git actions.
Additionally, we will integrate these steps with Hugging Face Spaces, focusing on building and project managing an AI product.

You will also learn to relate these practices to the Unified Process Traceability Matrix to identify and manage issues effectively.

Objectives - Set up a Git repository. - Understand and Gimanaget issues and actions. - Integrate Git with Hugging Face Spaces. - Relate Git actions to the Unified Process Traceability Matrix.
### Setting Up a Git Repository
Step 1: Install Git Before you start, ensure Git is installed on your machine. You can download Git from [git-scm.com](https://git-scm.com/).
Step 2: Configure Git After installation, configure Git with your username and email: ```bash git config --global user.name "Your Name" git config --global user.email "your.email@example.com"
Step 3: Create a New Repository Create a new directory for your project and initialize a Git repository: mkdir ai-product cd ai-product git init

Exercise 1: Basic Git Operations

1. **Create a README file**: ```bash echo "# AI Product" > README.md git add README.md git commit -m "Add README file" ```
2. **Create your first Python script**: ```python # hello.py print("Hello, AI World!") ``` Add and commit this file: ```bash git add hello.py git commit -m "Add hello.py script" ```
Proceed to connect your Local Repo to

Managing Git Issues and Actions


Step 4: Creating Issues Create issues to track bugs, enhancements, or tasks.
This can be done via the GitHub interface (or any Git hosting service you use). Navigate to your repository on GitHub and click on the "Issues" tab, then "New issue".
#### Step 5: Git Actions Perform actions to resolve these issues. Actions include creating branches, making commits, and merging changes.
### Exercise 2: Creating and Resolving Issues
1. **Create a new issue**: - Title: "Fix greeting message" - Description: "The hello.py script should greet the user by name."
2. **Create a branch for the issue**: ```bash git checkout -b fix-greeting ```
3. **Modify the script**: ```python # hello.py name = input("Enter your name: ") print(f"Hello, {name}!") ``` Commit your changes: ```bash git add hello.py git commit -m "Update hello.py to greet user by name" ```
4. **Push the branch and create a pull request**: ```bash git push origin fix-greeting ``` On GitHub, create a pull request to merge `fix-greeting` into `main`.
5. **Merge the pull request**: Once reviewed, merge the pull request and close the issue.
### Integrating with Hugging Face Spaces
#### Step 6: Set Up Hugging Face Repository 1. **Create a new Space on Hugging Face**: - Navigate to [Hugging Face Spaces](https://huggingface.co/spaces). - Click "New Space" and follow the prompts to create a repository.
2. **Clone the Hugging Face repository locally**: ```bash git clone https://huggingface.co/spaces/your-username/your-space cd your-space ```
3. **Copy your AI product files**: ```bash cp ../ai-product/* . git add . git commit -m "Initial commit with AI product files" git push origin main ```
### Exercise 3: Deploying to Hugging Face Spaces
1. **Modify your script for deployment**: - Ensure the script is compatible with the Hugging Face environment.
2. **Add a `requirements.txt` file**: ```bash echo "streamlit" > requirements.txt git add requirements.txt git commit -m "Add requirements file for dependencies" git push origin main ```
3. **Deploy**: Push your changes to Hugging Face and verify the deployment on the platform.
### Relating to Unified Process Traceability Matrix
#### Step 7: Traceability Matrix - **Define requirements**: Document user stories and requirements. - **Map requirements to issues**: Use the Traceability Matrix to ensure each requirement is tracked with corresponding issues.
### Exercise 4: Using the Traceability Matrix
1. **Create a Traceability Matrix**: - List requirements in the first column. - Map each requirement to Git issues in the second column. - Example: | Requirement | Git Issue ID | |-----------------------------|--------------| | User can enter their name | #1 |
2. **Create issues for each requirement**: - Ensure every requirement has a corresponding issue in your Git repository.
### Advanced Git Actions and Traceability
#### Step 8: Advanced Branching and Merging
1. **Create feature branches for new features**: ```bash git checkout -b feature-new-algorithm ```
2. **Develop and test new features**: - Ensure thorough testing before merging.
3. **Merge and close related issues**: ```bash git checkout main git merge feature-new-algorithm git push origin main ```
### Exercise 5: Advanced Git Actions
1. **Create an advanced feature branch**: - Implement a new AI feature. - Commit and push changes.
2. **Resolve complex merge conflicts**: - Simulate conflicts by having multiple branches with changes in the same file. - Resolve conflicts using `git merge` and push the resolved code.
Conclusion This workbook provides a comprehensive guide to managing Git repositories, handling issues and actions, and integrating with Hugging Face Spaces. By following these steps and completing the exercises, you will gain practical experience in project management and AI product development using Git.
