As an engineer, how you communicate with your teammates has a significant impact on project outcomes. Are you leveraging the power of async communication? Async communication refers to non-real-time communication that happens without an immediate response, such as messaging, email, wikis, and code repositories. Embracing async communication can transform how your engineering team collaborates and boost productivity.

When you communicate asynchronously, you give your teammates the flexibility to respond on their own schedule. This allows people to thoughtfully compose messages and responses without feeling rushed. It also creates space for more voices to be heard as people can respond in their own time.

Async communication leads to higher quality discussions and more inclusive decision making. It helps reduce meetings and prevents key discussions from happening only between those who were available at a particular point in time. By unlocking the power of async communication, you can build a more productive and empowered engineering team. The benefits are well worth the effort.

The Rise of Async Communication

The rise of asynchronous communication has transformed how engineering teams operate. Asynchronous communication refers to non-real-time communication that occurs with a delay, like email.

  • Email is the preeminent tool for asynchronous communication. It enables convenient digital correspondence regardless of time or place. Email allows ideas and information to be shared without requiring immediate response or action.

With the proliferation of remote work and globally distributed teams, asynchronous communication has become crucial for productivity and collaboration. Some of the key benefits of asynchronous communication for engineering teams include:

  1. Improved Focus. Asynchronous tools like email reduce interruptions and enable engineers to focus without distraction. This sustained concentration leads to higher quality work and greater productivity.
  2. Flexibility and Accommodation. Asynchronous communication provides flexibility to engineers in different time zones or with alternative work schedules. It allows participation and collaboration to happen on each person’s own timeline. This accommodation is essential for global and remote teams.
  3. More Thoughtful Exchanges. The delayed nature of asynchronous communication encourages more thoughtful, well- constructed messages. Engineers can take time to gather their thoughts, articulate them clearly, and provide helpful context or examples. These substantive and considered communications drive better discussions and outcomes.

With the rise of global connectivity and remote workforces, asynchronous communication has emerged as a powerful tool for engineering collaboration and productivity. By leveraging the benefits of asynchronous tools like email, engineering teams can unlock higher performance and innovation, regardless of time or place. Overall, the rise of asynchronous communication has revolutionised how engineering teams work together in our modern world.

The Benefits of Async Communication for Engineering Teams

As an engineering team, embracing asynchronous communication can significantly improve your productivity and workflow. Here are some of the major benefits of async communication:

Improved Focus. Async communication allows engineers to focus without distraction or interruption. By communicating asynchronously through tools like email, chat, and project management software, engineers can thoughtfully compose messages and responses on their own schedule without worrying about an immediate reply. This focused time allows for higher quality, well-thought out work.

Accommodating Different Work Styles. Async communication supports a diversity of work styles. Some engineers prefer to start work early, some late. Some work better in bursts, some work better with longer sustained periods of focus. Async communication gives engineers the flexibility to work when and how they are most productive.

Increased Inclusion. Async communication makes it easier for all members to participate and have their voices heard. Shy or introverted team members may feel more comfortable contributing via written communication versus speaking up in meetings. Async also gives non-native English speakers more time to compose and translate their thoughts. The result is a more inclusive environment where everyone can participate fully.

Better Documentation. With async communication, discussions and decisions are documented, searchable, and shareable. Email threads, chat logs, comments, and project updates create a rich archive of team knowledge and rationale that can be referenced at any time. This documentation helps avoid rehashing previous discussions and decisions, and brings new team members up to speed quickly.

In summary, by adopting asynchronous communication and collaboration tools, engineering teams can boost productivity, support work-life balance, increase inclusion, and enhance team learning. Async communication, when combined with a culture that values deep work and flexibility, is a key enabler of high-performing, innovative teams.

Improved Focus and Reduced Distractions

Working asynchronously allows engineers to focus without distraction. Removing constant interruptions from real-time messaging and meetings provides extended periods of concentration that lead to higher productivity and problem-solving.

Reduced Context Switching

When engineers can focus for longer periods without switching contexts, they can achieve a state of flow that boosts creativity and cognitive function. Studies show that for complex, problem-solving tasks like engineering work, it can take 15-30 minutes just to regain focus after an interruption. Async communication minimises disruptions and allows for fewer context switches, enabling engineers to stay in flow for longer.

Minimised Distractions

Real-time meetings and messaging can distract engineers from important work. Async communication reduces these distractions by allowing engineers to avoid constant notifications and choose when to respond. They can then set aside time for focused work without perpetual pinging from colleagues. Engineers can also choose to mute notifications from messaging apps and email when they need to concentrate.

Accommodation of Diverse Work Styles

Some engineers thrive on the energy of real-time collaboration while others prefer less stimulation to focus. Async communication accommodates diverse working styles by giving engineers more autonomy over their time. They can work when they are most productive and responsive, rather than adhering to standard work hours. This flexibility and control leads to higher job satisfaction, motivation, and performance.

Improved Work-Life Balance

With less demand for immediate response, async communication establishes boundaries between work and personal time. Engineers can step away from work outside of standard work hours without feeling pressured to respond right away. They gain more flexibility and balance in how and when they complete their work. For organisations that value work-life balance and employee well-being, async communication is an important tool.

In summary, async communication enhances focus, reduces distractions, accommodates different working styles, and promotes better work-life balance for engineers. By optimising conditions for high-performance work, async communication unlocks engineering productivity and innovation.

Better Work-Life Balance

Async communication allows for better work-life balance. When communication is primarily handled via platforms that enable asynchronous messaging, such as Slack or email, employees have more flexibility and control over their time.


Asynchronous communication gives employees the flexibility to respond to messages when it suits them. They can triage and respond to high-priority items immediately while low-urgency messages can be answered during less busy periods or when inspiration strikes. This flexibility leads to less interrupt-driven work and more time for focused work and thoughtful responses.

Less Meetings

With async communication, fewer real-time meetings are required. When communication is text-based, more discussions and decisions can happen without synchronous interaction. This results in more time that can be used for other work priorities or personal needs.

Accommodating Work Schedules

For global and remote teams, async communication is essential to accommodating diverse work schedules and time zones. When communication is not reliant on all parties being available at the same time, individuals have more autonomy to work when they choose. This asynchronicity leads to a better overall work-life balance as employees have more flexibility and control.

Reduced Stress

The flexibility, reduced meetings, and accommodation of diverse schedules that come with async communication lead to lower stress levels. Employees experience less anxiety from tight deadlines, last-minute requests, or the need to be "on" and available during traditional work hours. With more flexibility and autonomy, individuals can work in a way that suits their own productivity, energy levels, and work-life balance needs.

Async communication, when used as a primary mode of interaction in engineering teams, can lead to greater work-life balance through increased flexibility, fewer meetings, accommodation of diverse schedules, and overall reduced stress. By embracing asynchronicity, teams gain benefits that positively impact both work productivity and personal well-being.

Increased Inclusion and Diversity

Asynchronous communication enables increased inclusion and diversity within engineering teams. By removing the constraint of coordinating schedules across time zones, asynchronous communication opens the door to hiring the best and brightest talent regardless of location.

Expanded Talent Pool

With async communication, engineering teams have access to a global talent pool. They can hire the best candidates for a role regardless of their geographic location or time zone. This allows companies to build more diverse, inclusive teams with a range of experiences, perspectives and skill sets.

Flexibility and Work-Life Balance

Async communication also provides more flexibility and work-life balance for employees. Workers have more control over their schedules and can contribute whenever they have the opportunity rather than being tied to standardised work hours. This flexibility appeals to candidates from a range of backgrounds, including those with families or caregiving responsibilities.

Equal Opportunity to Contribute

In asynchronous communication, all voices have equal opportunity to contribute. Ideas and work are evaluated based on their merit rather than who contributed them or when. This results in an inclusive environment where people feel empowered to share their thoughts without judgement.

Mitigated Unconscious Bias

With names and identities obscured, unconscious biases are less likely to impact asynchronous discussions and decision making. All team members can feel confident their work and ideas will be considered objectively.

Engineering teams that adopt asynchronous communication and the best practices to support it will be poised to build more diverse, inclusive and globally distributed teams. They will have access to a wider range of talent and be able to provide more flexibility and work-life balance for all team members. Overall, asynchronous communication helps create an environment where people feel empowered to contribute their best work.

Higher Quality Discussions and Decisions

Asynchronous communication enables higher quality discussions and decisions in engineering teams.

More Thoughtful Contributions

With async communication, engineers have more time to thoughtfully consider questions and formulate comprehensive responses. They can gather data, check facts, and ensure their contributions are as accurate and helpful as possible. As a result, async discussions often contain more substantive content that moves projects forward in a meaningful way.

Increased Participation

By removing the demand for quick responses, async communication opens the door for more voices to join the conversation. Those who may feel less comfortable contributing in synchronous settings have the time they need to share their perspectives. Increased participation leads to greater diversity of thought and helps identify alternative solutions that may otherwise be missed.

Reduced Groupthink

The additional time to respond and broader range of participants decreases the likelihood of groupthink in engineering discussions. With more diverse opinions and an opportunity to challenge ideas, engineering teams can make higher quality decisions that account for more factors. Groupthink is a risk with any team, but async communication helps safeguard against it.

Documentation of Discussions

A significant benefit of async communication is that discussions are automatically documented. Engineering teams have a written record of questions, responses, key decisions, and the reasoning behind them. This documentation serves as a reference point, ensures alignment, and brings new team members up to speed quickly.

While async communication may require more time and effort, the rewards of higher quality discussions, improved decision making, increased participation, mitigated groupthink, and documented conversations are well worth it. Engineering teams that embrace asynchronous communication and understand its power will thrive.

Overcoming the Challenges of Async Communication

Overcoming the challenges of asynchronous communication requires diligence and conscious effort. Several strategies can help reduce misunderstandings and keep projects on track.

Clearly articulate thoughts

When communicating asynchronously, take extra care to express yourself clearly. Provide enough context and background information to paint a full picture for readers. Explain how ideas connect and build upon each other. Use specific examples to illustrate key points. Choosing words carefully and re-reading messages before sending can help avoid ambiguity.

Share work in progress

Don't wait until a task is complete to update colleagues. Share work in progress to keep everyone aligned and allow for feedback and input. Provide regular status updates, share drafts of documents, and summarize key takeaways from research or meetings. This level of transparency helps identify any misalignment early and prevents wasted effort.

Be explicit in requests

Asynchronicity means requests and questions may go unanswered for hours or days. Be very explicit in what you are asking for by providing detailed explanations and context. Explain why the information or input is needed and how it will be used. This helps ensure the response will be relevant and actionable when received. Follow up on any open requests or questions if you have not received a response after a reasonable amount of time.

Confirm understanding

With async communication, misunderstandings can easily arise and persist for days before being detected. Combat this by regularly confirming understanding in writing. For example, after a complex discussion, summarise the key outcomes and next steps to ensure alignment. When someone shares new ideas or provides a status update, reiterate your understanding of the main takeaways. These simple acts of confirmation strengthen connections and keep work flowing smoothly, even when teams are distributed and collaboration is asynchronous.

Following these best practices for async communication, though requiring conscious effort, can help unlock its significant benefits for engineering teams. With practice, these strategies will become second nature, enabling higher productivity, greater work-life balance, and more effective collaboration.

Choosing the Right Async Tools for Your Team

To leverage the benefits of asynchronous communication, choose tools designed specifically for async collaboration. Some options to consider:

Project Management Platforms

Project management platforms like Asana, Trello, and Basecamp are popular for managing async communication. They provide a central place to organise projects, assign tasks, share files, and comment on updates. Team members can check in, get caught up, and respond on their own timeline.

Wiki Tools

Wiki tools are useful for async knowledge sharing and documentation. Options like Confluence, Notion, and GitHub Wiki allow teams to build a knowledge base of resources, how-to's, and institutional knowledge that people can access anytime. Wikis give teams a single source of truth that keeps everyone on the same page.

Document Collaboration Software

Tools like Google Docs, Dropbox Paper, and Quip enable async document collaboration. Multiple team members can work on the same documents, spreadsheets, and presentations together while seeing each other’s changes in real-time. People can review, revise, and approve work according to their schedule.

Code Collaboration Platforms

For software engineering teams, code collaboration platforms are essential for async work. GitHub, GitLab, and Bitbucket allow developers to collaborate on code asynchronously by merging code changes, reviewing pull requests, providing line comments, and more. Teams can work together efficiently while coding on their own time.


While not specialised for async communication, email remains an important tool. It allows people to send messages, share updates, and request information without needing an immediate response. For async teams, establish expectations around email response times, such as within 48 hours. Also clarify when email is not the appropriate communication channel in favour of other tools.

With the right mix of tools in place, async communication can become second nature for your team. But choosing tools is only part of the solution. Teams must also establish guidelines for how and when to use each tool to be successful. The tools are only as good as the team's ability to leverage them.
