8 weeks · About 7 hours per week
System Behavior
Distinguish activity, action, and token-flow semantics well enough to explain why a decision node differs from a merge node
Construct an activity model containing initial/final nodes, decision/merge pairs, and a fork/join pair
Assign object flow to at least two action pins and justify each assignment against the action's input/output contract
Translate a short written operating procedure into an activity model without introducing unspecified ordering
Your checkpoint
One activity diagram with 10 or more actions, two object flows, and a written 5-line rationale for every control node used
System Behavior
Build a state machine with at least one composite state, an entry/exit behavior, and two mutually exclusive regions
Verify that every transition is triggered by a named event or guard, and remove any transition that relies on implied timing
Construct a sequence diagram that uses synchronous and asynchronous messages plus one combined fragment
Compare the same scenario expressed as a state machine and as an interaction, and state which construct is appropriate for which question
Detect and repair three behavioral defects (unreachable state, missing merge, ambiguous event) in a self-authored model
Your checkpoint
A state machine plus matching sequence diagram for one scenario, submitted with a defect log listing the three defects found and the fix applied to each
System Structure
Build a block definition diagram with at least 8 blocks, distinguishing composition from a plain association in words
Assign multiplicities to every association end and state the real-world meaning of each boundary value
Model generalization across at least two levels and confirm that each subtype is substitutable for its supertype
Define value properties with units and types, and reject any property typed as a free-text string where a value type is required
Your checkpoint
A block definition diagram of 8 or more blocks with multiplicities on all association ends, plus a one-paragraph substitutability argument for each generalization
System Structure & System Behavior
Construct an internal block diagram that wires parts through ports with matching types on each connector end
Trace each port in the internal view back to a declared feature on the corresponding block
Reconcile the structural model with the week-1 activity model so every action owner appears as a part
Explain, in writing, how a signal or item leaving one port is received by the connected part's behavior
Your checkpoint
A reconciled structural plus behavioral submodel for one subsystem, with a port-to-feature cross-reference table of every connector
Requirements
Write 12 atomic requirements using a fixed identifier scheme and a single testable statement each
Organize requirements into a containment hierarchy and eliminate any requirement that restates a design decision
Relate requirements to model elements using derive, satisfy, and verify relationships, choosing the correct one each time
Build a traceability matrix covering every requirement and flag any orphan element
Your checkpoint
A requirements package of 12 requirements with a traceability matrix showing zero orphan requirements and zero requirements without a verify relationship
Requirements & Cross-Cutting Constructs
Allocate behavioral elements to structural elements and read the resulting allocation back to confirm direction of the mapping
Apply a stereotype with a tagged value to at least three model elements and state what the tag adds beyond the base element
Define a value type with dimensions and units, then use it in two distinct places in the model
Construct one view conforming to a stated viewpoint, and articulate which stakeholder concern that viewpoint addresses
Your checkpoint
An allocation table plus one viewpoint-conforming view, with a short note for each entry explaining why that cross-cutting construct was chosen over an alternative
Cross-Cutting Constructs & System Behavior & System Structure & Requirements
Assemble the week 1 through week 6 artifacts into one coherent model of a single small system
Resolve every naming, typing, and multiplicity inconsistency surfaced during assembly
Diagnose personal weak areas using a scored self-test and rank the four domains by error rate
Re-teach each of the two lowest-scoring domains by rewriting its key rules from memory
Your checkpoint
One integrated model spanning all four domains, accompanied by a ranked weak-area list and a 1-page rewritten rule sheet for the two weakest domains
System Behavior & System Structure & Requirements & Cross-Cutting Constructs
Complete two timed full-length practice sets and log every miss by domain
Explain the reasoning behind each corrected miss in one sentence without referring to notes
Drill the constructs most often confused across domains until each distinction is stated correctly three times in a row
Finalize a pre-exam checklist of modeling conventions to apply before submitting any constructed answer
Your checkpoint
A timed practice score at or above your target threshold, plus a miss log in which every entry has a one-sentence self-explanation and a final convention checklist
Milestones
Week 2: Without notes, sketch a state machine and an activity for the same scenario and state the trigger, guard, and effect of every transition; any unanswered item resets week 2 review
Week 4: Given only the structural model, predict the sequence of messages at runtime and confirm the prediction against the week-2 behavioral model with no contradictions
Week 6: Produce the correct relationship type (derive, satisfy, verify, or allocate) for 10 randomly selected element pairs, scoring at least 9 of 10
Week 8: Score at or above your target on a timed full-length set with no domain below 70 percent, and complete the miss log with zero unexplained errors
