Human Factors in Software Engineering
If you think about software engineering as simply writing code, it is easy to overlook the other people who have an interest in the software products that you are creating. Fig. 1 illustrates some of the most important ones.
Communication and collaboration are fundamental to modern software development, shaping productivity, morale, and overall success. Teams must effectively share information to avoid misunderstandings, duplicated efforts, or overlooked requirements. For instance, if developers fail to communicate about changes in code, this can lead to integration issues that require time-consuming rework. Teams that utilize communication tools, hold regular meetings, and practice collaborative coding techniques like pair programming often work more cohesively and efficiently.
Emotional intelligence and empathy contribute significantly to a positive work environment both within the team and in its interactions with external stakeholder. When developers understand and manage their emotions, as well as show empathy towards colleagues, they foster better collaboration and resolve conflicts effectively. Applying the same skills to external relations makes the Agile process smoother with honest feedback and effective discussions.
Addressing and managing human factors — communication, team dynamics, diversity, leadership, motivation, and adaptability — can create a supportive environment where development teams thrive. Teams that prioritize these aspects tend to produce higher-quality work, adapt better to challenges, and maintain long-term productivity and morale.
External Stakeholders
A stakeholder is any person, group of people or organisation with an interest in a project. The client (or customer) obviously has an interest in the system being built: they have set the requirements and they are paying for it. Depending on the type of system and the context of use, however, there may be many other stakeholders that need to be considered as the development proceeds. The process of mapping out all of these separate concerns is called stakeholder analysis. You need to be aware that sometimes, your software development project may not be welcome and certain stakeholders may be resistant to the intended outcome. Identifying those negative interests can help you to avoid unexpected setbacks.
Smith, 2000 provides a clear explanation of how to conduct a thorough stakeholder analysis.
-
Identify the stakeholders
Starting with an initial brainstorming session, all possible interests are included. Candidate stakeholders may be dropped later if it becomes clear that they are not in fact concerned with the project.
-
Identify stakeholders’ interests, impact level, and relative priority
The next step is to gather the list of stakeholders into a convenient format such as a spreadsheet, to rate their level of potential impact on the project and rank them in terms of importance. Direct conversations with the stakeholders is useful at this stage.
-
Assess stakeholders for importance and influence
Influence is an indication of the control that a stakeholder has over the project. The client is very influential because they can terminate the project at any time. Importance quantifies the extent to which a stakeholder is critical for the success of the project. For example, if the target users are dissatisfied with the outcome, the project may be considered a failure.
As part of this step it can be useful to visualise stakeholders on a chart divided into four quadrants as shown in Fig. 2. Those in the top right quadrant are the key stakeholders for your project.

Outline assumptions and risks
Risk management in a software development project usually focuses on resource availability and technical risks. One of the benefits of performing a stakeholder analysis is that it offers a simple way to include sociopolitical risks into your thinking. This information can be added to the spreadsheet.
-
Define stakeholder participation
This final step is about making decisions about who should participate in the project and when. Some stakeholders just need to be kept informed; others need to be actively kept on-side.
Communication skills
To maintain strong and effective relationships with external stakeholders, a software developer needs a blend of social and analytical skills that enable clear communication, foster trust, and ensure that technical solutions align with stakeholder needs. One essential social skill is active listening. Developers who actively listen can understand stakeholder concerns, priorities, and requirements more accurately, which is crucial for translating business needs into technical solutions. When stakeholders feel heard, trust and mutual respect grow, creating a foundation for a productive, collaborative relationship.
Empathy is another critical social skill that allows developers to appreciate the perspectives and challenges of stakeholders, who may come from diverse professional backgrounds. By empathizing with stakeholders, developers can better align their solutions with real-world challenges, anticipate concerns, and address potential misunderstandings before they escalate. This sensitivity to others’ needs and constraints is invaluable when managing expectations, particularly if there are technical limitations or complex requirements.
Effective communication is indispensable, as developers often need to explain technical concepts in a clear and accessible manner to non-technical stakeholders. Simplifying complex ideas and avoiding jargon help prevent misinterpretations, making it easier for stakeholders to understand progress, challenges, and the reasoning behind technical decisions. Regular, transparent communication helps stakeholders feel informed and valued, which is essential for long-term trust.
On the analytical side, problem-solving skills are essential for addressing the dynamic needs of external stakeholders. Stakeholders frequently bring forward new requirements or unexpected issues that require immediate attention. A developer’s ability to analyze problems from both a technical and a stakeholder perspective allows them to propose feasible, effective solutions that satisfy project goals and timelines. Strong problem-solving skills also help in identifying risks early and preparing strategies that can prevent potential issues.
Adaptability and flexibility are also crucial analytical skills, as external requirements and expectations can shift during a project. Developers who can adjust their approach, accommodate changes, and remain responsive to feedback demonstrate their commitment to meeting stakeholder needs. Flexibility also allows developers to pivot quickly when business goals shift, which is common in fast-paced projects or competitive industries.
Another key analytical skill is attention to detail. Meeting stakeholder expectations often hinges on precision in implementing specifications, adhering to agreed timelines, and catching potential issues before they escalate. Details matter, especially when working on features that directly impact the end-user experience or address specific business objectives. Developers who are detail-oriented can better ensure that the delivered solution aligns exactly with stakeholder expectations.
Finally, stakeholder management — which combines social and analytical skills — is necessary for balancing technical decisions with stakeholder priorities. Developers need to manage expectations effectively, providing realistic timelines, explaining the impacts of decisions, and clarifying dependencies. Good stakeholder management includes knowing when to negotiate and prioritize certain tasks based on the stakeholder’s strategic goals, while ensuring that technical standards and project quality are maintained.
The team
Team dynamics and relationships play a crucial role in how a team functions. Teams that trust and respect one another are more likely to support each other and collaborate effectively. Conversely, conflicts or negative interactions can create a toxic environment that stalls progress. For example, a team where certain members dominate decision-making without considering others’ input may struggle with morale and decreased motivation.
Diversity and inclusion within a team contribute to broader perspectives and better problem-solving capabilities. A development team that includes members from different backgrounds may approach a feature or problem in varied, innovative ways, leading to more comprehensive solutions. Without a commitment to inclusion, teams risk falling into groupthink, where creativity and fresh ideas are stifled.
The skills and experience levels within a team can also significantly influence productivity and knowledge-sharing. A balanced team that includes junior, mid-level, and senior developers can foster mentorship and skill development. For example, senior developers can guide less experienced team members on best practices and architecture decisions. However, an imbalance where the team has too many juniors without enough guidance from seniors can lead to inefficiencies and technical debt.
Motivation and engagement are key to sustained productivity. Developers who are motivated often take ownership of their work and strive for high-quality output. A team working on a challenging and meaningful project, with clear goals and recognition from leadership, is more likely to stay engaged. On the other hand, a lack of engagement can result in minimal effort, higher error rates, and decreased output quality.
Leadership and management style have a profound effect on team performance. Leaders who empower their teams, encourage autonomy, and provide guidance contribute to a positive, high-functioning environment. For instance, a supportive project manager who listens to concerns and facilitates solutions can maintain team morale and productivity. On the contrary, micromanagement or an absence of leadership can lead to frustration and demotivation.
Maintaining a healthy work-life balance is essential to prevent burnout and ensure long-term productivity. When developers consistently face high stress and long hours, their output and morale suffer. Teams that foster a balance, such as offering flexible work hours or recognizing the importance of downtime, are more resilient and productive over time.
Clearly defined roles and responsibilities help team members understand their contributions to the project. Ambiguity can lead to task duplication or essential tasks being overlooked. For example, if two developers assume someone else is responsible for a critical feature, it may not be completed on time. Defining roles ensures everyone knows their focus areas, which streamlines work processes and minimizes conflicts.
Adaptability to change is another crucial factor in the fast-paced world of software development. Teams that embrace new tools, processes, or project shifts stay competitive and relevant. A team open to adopting an updated framework can often deliver projects more efficiently, while teams resistant to change may find themselves lagging behind. A well-known case of adaptability having a positive effect on morale and productivity is provided by the Hawthorne Effect based on a series of experiments in an electrical factory in America in the 1920s.
A culture of feedback and continuous improvement is important for growth and maintaining high standards. Teams that regularly engage in constructive feedback, such as through code reviews or retrospective meetings, can identify areas for improvement and make necessary adjustments. For instance, feedback in a code review may highlight a more efficient algorithm, improving overall code quality. In contrast, a lack of feedback stifles development and leaves potential issues unaddressed.
Problem-solving and decision-making approaches also affect a team’s progress. Teams that collaborate openly and consider diverse ideas often reach better solutions faster. For example, a team brainstorming session that includes developers, testers, and product managers can result in a more robust feature design. However, if decision-making is overly centralized with just a few individuals, it can delay progress and reduce team engagement.
