A cross-functional team is a group of people with different functional expertise working toward a common goal. It may include people from finance, marketing, operations, and human resources departments. Typically, it includes employees from all levels of an organization. Members may also come from outside an organization (in particular, from suppliers, key customers, or consultants).
Cross-functional teams often function as self-directed teams assigned to a specific task which calls for the input and expertise of numerous departments. Assigning a task to a team composed of multi-disciplinary individuals increases the level of creativity and out of the box thinking. Each member offers an alternative perspective to the problem and potential solution to the task. In business today, innovation is a leading competitive advantage and cross-functional teams promote innovation through a creative collaboration process. Members of a cross-functional team must be well versed in multi-tasking as they are simultaneously responsible for their cross-functional team duties as well as their normal day-to-day work tasks. Decision making within a team may depend on consensus, but often is led by a manager/coach/team leader. Leadership can be a significant challenge with cross-functional teams. Leaders are charged with the task of directing team members of various disciplines. They must transform different variations of input into one cohesive final output. Cross-functional teams can be likened to the board of directors of a company. A group of qualified individuals of various backgrounds and disciplines are assembled to collaborate in an efficient manner in order to better the organization or solve a problem.
The growth of self-directed cross-functional teams has influenced decision-making processes and organizational structures. Although management theory likes to propound that every type of organizational structure needs to make strategic, tactical, and operational decisions, new procedures have started to emerge that work best with teams. 
Up until recently, decision making flowed in one direction. Overall corporate-level objectives drove strategic business unit (SBU) objectives, and these in turn, drove functional level objectives. Today, organizations have flatter structures, companies diversify less, and functional departments have started to become less well-defined. The rise of self-directed teams reflects these trends. Intra-team dynamics tend to become multi-directional rather than hierarchical. Interactive processes encourage consensus within teams. Also the directives given to the team tend to become more general and less prescribed.
Greater scope of information
Cross-functional teams require a wide range of information to reach their decisions. They need to draw on information from all parts of an organization’s information base. This includes information from all functional departments. System integration becomes important because it makes all information accessible through a single interface. An inherent benefit of a cross-functional team is the breadth of knowledge brought to the group by each member. Each team member is a representative of a department and therefore can leverage their familiarity with accessing and providing knowledge of that department for the team. This increases the efficiency of a cross-functional team by reducing time spent gathering information.
Greater depth of information
Cross-functional teams require information from all levels of management. The teams may have their origins in the perceived need to make primarily strategic decisions, tactical decisions, or operational decisions, but they will require all three types of information. Almost all self-directed teams will need information traditionally used in strategic, tactical, and operational decisions. For example, new product development traditionally ranks as a tactical procedure. It gets strategic direction from top management, and uses operational departments like engineering and marketing to perform its task. But a new product development team would consist of people from the operational departments and often someone from top management.
In many cases, the team would make unstructured strategic decisions—such as what markets to compete in, what new production technologies to invest in, and what return on investment to require; tactical decisions like whether to build a prototype, whether to concept-test, whether to test-market, and how much to produce; and structured operational decisions like production scheduling, inventory purchases, and media flightings. In other cases, the team would confine itself to tactical and operational decisions. In either case it would need information associated with all three levels.
Greater range of users
Cross-functional teams consist of people from different parts of an organization. Information must be made understandable to all users. Not only engineers use technical data, and not only accountants use financial data, and not only human resources personnel use HR data. Modern organizations lack middle managers to combine, sort, and prioritize the data. Technical, financial, marketing, and all other types of information must come in a form that all members of a cross-functional team can understand. This involves reducing the amount of specialized jargon, sorting information based on importance, hiding complex statistical procedures from the users, giving interpretations of results, and providing clear explanations of difficult. Data visualization systems can present complex results in an intuitive manner.
Less goal dominated
Since the publication of Peter Drucker’s views on Management by objectives, business decision making has become more goal-oriented. Managers have come to view decision-making generally, and strategic thinking in particular, as a multi-stage process that starts with an assessment of the current situation, defining objectives, then determining how to reach these objectives. Management by objectives took this basic scheme and applied it to virtually all significant decisions.
Today many firms have started to opt for a less structured, more interactive approach. One way of implementing this involves using self-directed cross-functional teams. Proponents hope that these teams will develop strategies that will re-define industries and create new “best practice”. They think that incremental improvements do not suffice.
Cross-functional teams, using unstructured techniques and searching for revolutionary competitive advantages, allegedly require information systems featuring increased interactivity, more flexibility, and the capability of dealing with fuzzy logic. Artificial intelligence may one day be useful in this aspect.
