Modern software development often faces common challenges: siloed teams, communication breakdowns, and slow adaptability. Agile LeSS (Large-Scale Scrum) frameworks require cross-functional teams to address these problems effectively. But what kind of engineers are best suited to this model? Enter the concept of engineer “shapes” and the standout role of T-shaped engineers.

Engineer Shapes Explained:

  • I-Shaped Engineers: These individuals have deep expertise in a single domain but often struggle to collaborate effectively outside their specialty. While essential for specific tasks, they can unintentionally reinforce silos within teams.
  • T-Shaped Engineers: Combining deep expertise in one area with a broad understanding of other disciplines, these engineers are highly versatile and collaborative.
  • M-Shaped Engineers: With deep expertise in multiple areas, these individuals are highly skilled but may become overextended, making them less effective in small, agile team environments.

Why T-Shaped Engineers Are The Best Fit:

  1. Collaboration: T-shaped engineers act as connectors, bridging gaps between team members and ensuring effective communication. Their understanding of other disciplines allows them to contribute meaningfully and support their teammates.
  2. Flexibility: Their broad skill set allows them to adapt and step into various roles when needed, ensuring the team remains agile and resilient.
  3. Knowledge Sharing: T-shaped engineers foster a culture of learning and mentorship, strengthening the entire team and promoting continuous improvement.

The Role of T-Shaped Engineers in Cell-Based Infrastructure: In Agile LeSS frameworks, teams are structured like cells — small, autonomous, and scalable units. These teams thrive when members can collaborate seamlessly and adapt to changing needs. T-shaped engineers align perfectly with this model by balancing specialized expertise with a willingness to contribute broadly. This balance ensures the team functions efficiently, avoiding bottlenecks or dependencies on specific individuals.

How to Build T-Shaped Teams:

  • Training Programs: Encourage initiatives like pair programming, cross-training, and workshops to expand engineers’ skill sets.
  • Role Rotations: Allow team members to work in different areas, broadening their understanding of the project and their teammates’ challenges.
  • Hiring Practices: Seek candidates with both deep expertise and a proven ability to collaborate and learn new skills.
  • Promote a Learning Culture: Encourage continuous learning and provide resources for engineers to grow their breadth of knowledge.

Tips for Hiring T-Shaped Engineers:

  1. Tailor Job Descriptions: Emphasize the importance of both technical depth and collaboration skills in your job postings. Highlight a preference for candidates who have shown flexibility in past roles.
  2. Use Behavioral Questions: During interviews, ask candidates to describe scenarios where they stepped out of their expertise to support a team. Look for evidence of adaptability and teamwork.
  3. Collaborative Tasks: Incorporate team-based exercises or pair programming sessions in the hiring process to observe how candidates interact with others.
  4. Foster Continuous Growth: Provide a clear path for professional development, including opportunities to broaden knowledge and cross-train with peers.

Practical advice for new engineers:

  • Start Broad: Early in your career, explore multiple domains to build foundational knowledge across disciplines. This approach will help you identify your strengths and areas of interest.
  • Develop Communication Skills: Practice explaining complex technical concepts to non-technical teammates. Effective communication is a hallmark of T-shaped professionals.
  • Embrace Learning Opportunities: Participate in cross-functional projects, attend workshops, and seek mentors to grow both your depth and breadth of skills.
  • Be Open-Minded: Adaptability is key in dynamic environments. Be willing to step out of your comfort zone to support your team’s success.

T-shaped engineers are the backbone of effective, cross-functional teams, especially in Agile LeSS frameworks. They bring the perfect mix of depth and breadth, enabling teams to collaborate, adapt, and scale effectively. By investing in building T-shaped skills within your teams, you’re not just solving today’s challenges — you’re creating a foundation for long-term success in a fast-changing industry. For new engineers, cultivating a T-shaped mindset from the start can set you apart as a valuable and versatile team member. Start fostering these skills today to shape the future of your organization and career.
