The short answer is that a team with authority, knowledge and execution capacity must participate. The longer answer is more interesting: participating does not mean attending meetings. It means having a clear mandate to decide on scope, budget, user experience, security and business continuity. A business software project is a sociotechnical system; if only engineers participate, the result will be technically correct but disconnected from operations. If only executives participate, it will be a project full of intentions but without real validation. The balance lies in governance that represents every angle.
First, the executive sponsor. This is not the person who signs the budget and disappears. It is the person with authority to unblock conflicts between departments, approve scope changes and communicate the strategic priority of the project. Without a sponsor with real power, decisions are postponed and the team loses legitimacy. They do not need to know how to program; they need to know how to govern.
Second, the product or process owner. This role is the custodian of the business vision. Unlike the sponsor, their work is operational: they prioritize the backlog, define acceptance criteria, resolve functional questions and accept or reject deliverables. In projects that build custom software, this role is essential because real needs are not in a manual; they are in how people work, in the exceptions that are not documented and in the metrics the company wants to move. The product owner must have dedicated time; it cannot be a 'marketing manager who helps out'.
Third, business users. They are often consulted at the beginning and at the end, but not during the process. That creates a classic mismatch: software fulfills what is written in the requirements, but not what operations need. Users must participate in the definition of user stories, in functional tests and in the training of early adopters. Not everyone can attend every meeting; communities of practice or reference groups can be created with one representative per area. The key is that the dialogue is continuous, not an isolated event.
The next group is technology and architecture. It includes software engineers, system administrators, data architects and integration specialists. Their role is to transform needs into a viable, sustainable and secure solution. In today's world, this group must make decisions about AWS/Azure cloud, cybersecurity and interoperability with reporting tools such as BI/Power BI. If architecture is decided after validating scope, the project can become more expensive. That is why technical people must be present from the beginning, not when a date has already been promised.
Another key profile is the data owner. Many business software solutions depend on master data, operations data and financial data. If no one knows the semantics of each field, its origin and its quality rules, the solution will produce reports that look brilliant but are unreliable. The data owner's participation is necessary to design the data model, avoid duplicates and ensure that the indicators management will see are auditable. In addition, their work connects with cybersecurity: knowing who can access each piece of data, for how long and with what justification.
This is where AI agents come in. When a solution incorporates artificial intelligence, the project team needs to define not only the algorithm, but the confidence threshold, the feedback loop and the human intervention mechanism. AI is not a component added at the end; it changes how data is captured, how models are trained and how errors are measured. In this context, the participation of business managers is even more important, because they are the only ones who can say whether an automated decision makes sense in the real world. AI agents must operate with clear rules, and those rules are not defined by IT alone: they are defined by business, legal and operations together.
The compliance and risk function is also essential. Depending on the sector, it can include data protection, legal compliance, internal audit or fraud prevention. Involving these people from the beginning prevents discovering at the end that the design does not meet a regulation. It is not about them attending all technical meetings; it is about them validating critical flows, privacy policies and activity logs. The earlier non-compliance is detected, the cheaper it is to fix. The authority of the risk area must be real; a software project cannot weaken internal controls.
Change management is another function that is often forgotten. Business software solutions do not end when deployment is done; they begin when people use them. A change management team helps identify resistance, design training, create FAQs, collect incidents and adjust the system in the first months. This function must be connected to business users, but also to the technical team for continuous feedback. Adoption is not a communication problem; it is a design problem, and it must be treated as part of the product work.
At Q2BSTUDIO, as a software development and technology company, we work with a combination of these profiles in every project. We help organizations set up a small steering committee, define delivery rhythms and establish measurable acceptance criteria. We also provide specialized expertise in custom software, process automation, AWS/Azure cloud, cybersecurity, BI/Power BI and AI agents. Our role is not to replace internal teams, but to complement them with a technical and strategic perspective that connects technology with business results.
The conclusion is that there is no universal template of participants. There is, however, a universal principle: everyone who has information, risk or responsibility over an outcome must have a mechanism to contribute that information or veto decisions. The size of the group can vary, but roles cannot remain empty. If a project has no sponsor, someone will pay the bill without knowing why. If it has no product owner, everyone will decide and no one will answer. If it has no real users, the tool will be beautiful in the demo and useless day to day. If it has no architecture, technical debt will become a barrier to growth. And if it has no ethical and regulatory oversight, project speed will become a risk to the organization.
So when a company asks who should participate in business software solutions, the right answer is not a name, but a system of roles with clear responsibilities. That system must include management, business, technology, data, end users and control functions. And it must remain alive throughout the project lifecycle, because a business software solution is always evolving. Participation is not an event; it is the structure that makes software work as part of the company.
