Reading
The organizational structure a CM operates within materially affects their authority. This is an often-missed area because candidates memorize definitions without connecting them to what actually happens when two departments want the same person on the same day.
Functional organization: authority stays with the department
Staff report through discipline-based departments (engineering, estimating, scheduling), each with its own manager. A CM working within a functional organization has low authority. They must negotiate for resources through functional managers who control staff assignments, priorities, and performance reviews. If a scenario says staff "report to their department head first" or must "get approval before committing time," that is functional or weak-matrix language, and the CM's unilateral authority is limited.
Projectized organization: authority moves to the CM
Staff report directly to the CM or project manager for the duration of the project; functional departments barely exist, if at all. The CM has high authority: full control over project resources and staff assignment, without having to negotiate for anyone's time. The tradeoff is that specialized staff may sit idle between projects, since there is no functional department to reassign them when project work slows.
Matrix organizations: a hybrid, and it comes in three strengths
In a matrix organization, staff have dual reporting lines: a functional manager and a project manager. Authority scales with the matrix's "strength."
Weak matrix: Authority favors the functional manager; the CM acts more as a coordinator or expediter, tracking and facilitating work without much power to direct it.
Balanced matrix: Authority is roughly shared. This sounds fair on paper and can produce friction in practice, because neither party can decide alone when the two disagree.
Strong matrix: Authority favors the CM, who resembles a projectized-organization PM, though functional departments still formally exist.
CM authority rises left to right as the organizational structure moves from Functional toward Projectized.
When formal authority is limited: leading through influence
In a weak or balanced matrix, a CM's formal authority alone often isn't enough to get disputed work done. Experienced CMs fall back on influence that doesn't depend on the org chart: expert credibility (being visibly right about the technical or schedule consequences), relationship trust built before the conflict happened, and simply making the tradeoffs and their cost visible to whoever does have the authority to decide. The exam sometimes frames this as "the CM has no formal authority to resolve X, so what should they do", and the best answer is usually to escalate with a clear, data-backed recommendation, not to act unilaterally as if authority existed that doesn't.
Organizational Breakdown Structure (OBS) and the responsibility assignment matrix
Where the Work Breakdown Structure (Day 3) decomposes what has to be done, the Organizational Breakdown Structure shows who the organization is, department by department or role by role. Overlaying the WBS against the OBS produces a responsibility assignment matrix, commonly built as a RACI chart, marking who is Responsible for doing the work, who is Accountable for its outcome, who must be Consulted before a decision, and who merely needs to be Informed after one. A scenario that describes confusion over "who actually signs off on this" is testing whether you recognize a missing or poorly defined RACI, not a scheduling problem.
Why this matters for the exam
Organizational structure questions test two things at once: can you name the structure from the clues in the scenario, and can you correctly predict how much unilateral authority the CM has inside it. A CM who acts as if they have projectized-level authority inside a functional organization is the wrong answer just as often as a CM who over-escalates inside a projectized one.
Practice Questions
1. In a projectized organization, the CM's authority over project staff is:
Determined solely by the client, whatever the reporting lines
Nonexistent
High: staff report directly to the CM
Low
Answer: c. Projectized means the project is the organizing unit. Staff report to the CM, so the CM controls assignment, priority, and performance without negotiating for anyone's time.
2. A team member who must get approval from their department head before committing time to your project most likely operates in a:
A pure projectized organization with a dedicated project team
IPD structure
Functional or weak matrix organization
Strong matrix or projectized organization
Answer: c. Needing a department head's approval to commit time is the defining symptom of functional authority. The functional manager owns the person; the CM borrows them.
3. In a balanced matrix, authority between the functional manager and the CM is generally:
Roughly shared
Undefined by design
Entirely with the functional manager
Entirely with the CM
Answer: a. Balanced matrix splits authority roughly evenly between the functional manager and the CM. It sounds fair, and it can create friction, because neither party can decide alone.
4. A CM acting mostly as a "coordinator/expediter" without much unilateral authority likely operates in a:
Balanced matrix
Weak matrix
Strong matrix
Projectized organization
Answer: b. Coordinator or expediter language signals limited authority. The CM can facilitate and track but cannot direct, which describes the weak matrix.
5. Which structure most resembles a projectized organization in terms of CM authority, while still retaining functional departments?
Balanced matrix
Purely functional
Weak matrix
Strong matrix
Answer: d. Strong matrix keeps functional departments intact but gives the CM most of the authority over project work. It is the closest thing to projectized without dissolving the departments.
6. In a purely functional organization, who controls staff assignments to the project?
Functional/department managers
The contractor
The CM
The owner, through the project sponsor's approval of each assignment
Answer: a. In a purely functional organization the department manager owns the staff and decides what they work on. The CM has no claim on anyone's time except through that manager.
7. A CM with limited formal authority in a weak matrix wants a disputed task prioritized. The best approach is generally to:
Ignore the conflict and hope it resolves itself
Assume projectized-level authority since the project needs it
Direct the functional staff unilaterally, then inform the department head afterward and cite the project schedule as justification
Escalate with a clear, data-backed recommendation to whoever holds the authority to decide
Answer: d. Acting as if authority exists that doesn't is a common wrong answer. The CM's real lever in a weak matrix is credible influence and clear escalation, not unilateral direction.
8. The Organizational Breakdown Structure (OBS) is best described as:
A schedule of staff vacations
A decomposition of project scope into work packages
A representation of the organization's departments or roles, used to assign responsibility for WBS elements
A synonym for the WBS
Answer: c. The OBS represents who the organization is. Overlaid against the WBS (what has to be done), it produces the responsibility assignment matrix.
9. In a RACI chart, a person marked "A" for a task is:
Accountable for the outcome, even if someone else performs the work
Assigned to perform the work day to day, with no accountability for its outcome
Merely informed after the decision is made
Consulted before the decision, but not accountable for it
Answer: a. Accountable means owning the outcome and the sign-off, which is a different role from Responsible (doing the work), Consulted (giving input beforehand), or Informed (notified afterward).
10. A scenario describes repeated confusion over "who actually signs off on this deliverable." This most directly points to:
A scheduling delay
A missing or poorly defined responsibility assignment matrix
A cost overrun
A quality control failure unrelated to organization
Answer: b. Confusion about sign-off authority is an organizational assignment problem, not a technical one. It is exactly what a RACI chart, built from the OBS and WBS together, exists to prevent.
11. Which organizational structure trades higher CM authority for the risk that specialized staff sit idle between projects?
Balanced matrix
Functional
Weak matrix
Projectized
Answer: d. Projectized organizations give the CM full control but have no functional department to reassign specialized staff when project work slows, unlike functional or matrix structures.
12. Which is the best description of a strong matrix organization?
Functional departments are dissolved entirely and every staff member reports only to the CM
Authority favors the CM, but functional departments still formally exist
Authority is split exactly evenly with no exceptions
The CM acts purely as a coordinator
Answer: b. A strong matrix shifts real authority to the CM while keeping the functional department structure intact on paper, distinguishing it from a fully projectized organization.
13. Dual reporting lines, one functional and one to the project, are the defining feature of:
Projectized organizations
Matrix organizations of any strength
Strong matrix organizations only, not weak or balanced ones
Functional organizations
Answer: b. Dual reporting, to a functional manager and to the project side, defines a matrix organization. What varies by matrix strength is how much authority each side actually carries.
14. A CM who directs functional staff unilaterally inside a weak matrix, bypassing the department head, is most likely:
Overstepping the authority the structure grants, which risks conflict and undermines the functional manager's role
Required by the owner's contract whenever the project schedule is at risk and the department head is unavailable
Improving efficiency with no downside
Acting correctly, since the project's schedule and budget always outrank the department head's priorities
Answer: a. In a weak matrix the functional manager retains real authority over staff. A CM who bypasses that repeatedly damages the working relationship the CM depends on for every future request.
Micro-Assignment
Think of a team you've worked on (construction or otherwise). Identify its structure type (functional, weak/balanced/strong matrix, or projectized) and write 3-4 sentences describing one real resource conflict and how the structure's authority balance shaped how it got resolved. Then sketch a simple RACI for one deliverable from that project: who was Responsible, Accountable, Consulted, and Informed.
Glossary
Functional organization
Staff organized and managed by discipline department; low CM authority.
Projectized organization

Dual reporting (functional and project); authority varies by matrix strength (weak, balanced, strong).
Organizational Breakdown Structure (OBS)
A representation of the organization's departments or roles, used alongside the WBS to assign responsibility.
Responsibility assignment matrix
A chart, commonly a RACI, mapping WBS elements against the OBS to clarify who does what.
RACI
Responsible, Accountable, Consulted, Informed: the four roles a responsibility assignment matrix typically assigns.
Coordinator/expediter
A limited-authority PM role, typical of a weak matrix, that tracks and facilitates work without directing it.
