Introduction
The evolution of open source software development is moving away from traditional models, steering towards a more inclusive and collaborative framework.This whitepaper delves into community-led development (CLD) and participatory design (PD) roles within this transformative context.These methodologies are central to a broader movement that aspires to democratize technology creation and stimulate innovation.The discussion aims to reveal how their integration improves the development process and enhances the open-source initiatives.
In the active open-source landscape, blending community insights and stakeholder engagement through CLD and PD is a critical strategy for developing robust and innovative solutions.This paper highlights the contributions of these approaches in creating adaptable and resilient software while fostering an environment where diversity of thought and collaboration are highly valued.By exploring the implementation and outcomes of CLD and PD within the open-source ecosystem, the paper illuminates a path towards a future characterized by technological advancement driven by inclusivity, shared ownership, and collaboration.

Community-Led Development (CLD)
Community-Led Development (CLD) refers to a development approach where the community members collaboratively identify their goals and objectives, develop and implement strategies to achieve them, and foster relationships within the community and with external parties [1].This approach leverages the community's collective strengths and leadership to make progress in the project.
In the context of open source, CLD is characterized by several key attributes: Participation, Inclusiveness, sustainability, accountability, community leadership, adaptability, and collaboration [1].CLD focuses on the importance of everyone working together and having a say in decisions.This method ensures that the people involved are responsible for the project's development and final results.It fosters a more vibrant and resilient community that leads to the creation of software reflecting the diverse needs and insights of its users and contributors.

2.2Participatory Design (PD)
Participatory Design (PD) is a collaborative design methodology that emerged from Scandinavian work-life research in the 1970s, focusing on involving stakeholders, especially users, in the design process.Its roots in co-creation, democracy, and mutual learning highlight the importance of engaging all participants in shaping the outcomes to meet their needs and enhance usability [2], [3].This approach democratizes the design process, bridging the gap between developers and users to ensure products are both functional and reflective of diverse user requirements.
PD fits nicely in open-source software development with the key ideas of being open, working together, and involving the community.It means bringing users into the process of making the software, from the first design steps to making ongoing improvements.This approach ensures the software is robust from a technical point of view and truly meets what users need and want.By encouraging everyone to share their ideas and keep giving feedback, PD helps create creative, flexible software that meets the needs of the people using it.Incorporating this method in open source makes the projects more lasting and impactful.

Historical Context and Relevance
Integrating CLD and PD into open-source projects is a major transition in software development.In the past, software development was top-down, directed mainly by a small group of developers or project leaders, who made most of the decisions with little input from the actual users or the wider community [4].Although this method worked in some situations, it often led to software that did not fully meet the needs of its users or benefit from the community's collective knowledge.
The emergence of open source software has changed the game by promoting a more open, collaborative way of creating software, emphasizing working together, being transparent, and sharing ownership [4].Within this environment, CLD and PD have helped to make the development process even more democratic.CLD lets community members have a say in the direction of a project, ensuring it grows in line with what users need and want.PD goes hand in hand with CLD by involving users in designing the software, ensuring it is functional and userfriendly.
This move towards an inclusive and collaborative approach in software development is important because it means projects are more likely to stay relevant and keep up with changes [5].By getting a wide range of ideas and expertise from the community, open-source projects can innovate faster and create solutions that more people can use and support.Bringing CLD and PD into open source reflects a more significant change toward making technology development unbiased and collaborative, where everyone has a chance to contribute.

Implementing CLD and PD in open-source projects means using an organized plan but still being flexible enough to handle the ways communities work and what they aim to achieve.The starting point is to make sure everyone knows what the project is about, its vision, its values, and how contributors can get involved [6].This step involves setting up easy-to-use tools for sharing ideas and working together, like forums, messaging apps, and project management systems.These tools are crucial for clear and open communication among everyone involved [7].
Keeping the community active and interested takes continuous effort.It can be done by regularly sharing updates, recognizing the work people contribute, and creating a friendly space where all feedback is valued.Implementing recognition programs and contribution guidelines can help maintain a high level of participation and ensure that contributions are aligned with the project's vision and goals.
In order to facilitate collaborative development and design, it is important to have tools that help work together in real-time, like Discord or Slack, keep track of changes, and manage tasks via GitHub issues or Jira [8].These technologies make the process of building the project more efficient and allow people from anywhere to add their contributions, no matter their location or time zone.

Challenges and Solutions
Integrating CLD and PD into open-source projects presents several challenges [2] -Ensuring Inclusivity, Balancing Stakeholder Expectations, Addressing Long Feedback Loops, and Balancing Rapid Innovation with Stability.

Ensuring Inclusivity
• Challenge: Inclusivity is essential for creating a welcoming and diverse community where all voices are heard and valued.However, achieving true inclusivity can be challenging, especially in large and diverse communities.
• Solution: Actively promote diversity and inclusion within the community by creating policies, initiatives, and resources that support underrepresented groups [10].
• How it relates: Enabling diversity and inclusion ensures that community members from all backgrounds feel welcome and valued [10].The community benefits from broader perspectives and experiences by actively seeking and amplifying diverse voices.This enriches the collective pool of knowledge and creates a welcoming environment for all contributors, ultimately leading to a stronger and more resilient community.

Balancing Stakeholder Expectations
• Challenge: Balancing the needs and expectations of various stakeholders, including users, developers, sponsors, and other community members, can be challenging, as their priorities may differ.
• Solution: Prioritize Stakeholder engagement by actively engaging with them throughout the development cycle to ensure project goals and priorities align with their needs and expectations [11].
• How it relates: Prioritizing stakeholder engagement fosters a sense of ownership and commitment among all parties involved in the project.By obtaining input and feedback from stakeholders early and often, the project can better align its goals with the needs of its diverse user base.

Addressing Long Feedback Loops
• Challenge: In integrating CLD and PD, projects may encounter long feedback loops, extending the time between proposing a change and seeing it implemented or receiving feedback.This can slow the development cycle and impact the timely release of new features or updates [2].
• Solution: Implement more efficient tools and processes for collecting and acting on community feedback.This could include regular sprint reviews, where community input is gathered and prioritized for action, or real-time collaboration tools to accelerate decisionmaking processes [12].
• How it relates: By streamlining how feedback is collected and responded to, projects can reduce the time it takes to implement changes or introduce new features.This keeps the development cycle agile and ensures that community contributions have a real impact on the project's progress, maintaining engagement and satisfaction among contributors.However, this can sometimes compromise the stability, especially in projects critical to users' operations or businesses.

Balancing Rapid Innovation with Stability
• Solution: Adopt a Dual-Track Development Approach [13] as shown in figure 3: One possible strategy is to separate the project's development into two tracks: one focused on rapid experimentation and innovation (often in an edge environment) and another on maintaining a stable, thoroughly tested release for production use.This approach allows participatory design and community-led development to thrive without compromising the project's stability.
• How it relates: A dual-track development strategy finds a middle ground between wanting to innovate and needing to keep things stable.This approach creates a win-win situation for everyone involved, ensuring the project meets both its innovative goals and the users' need for reliability.
