Project Fundamentals and the Project Lifecycle
Week 1 sets the vocabulary the whole course is written in: the PMBOK definition of a project, the five process groups and the level-of-effort lifecycle, and the difference between a Methodology, a Technique and a Tool. This recall — process-group names, what happens in initiation, project-versus-operations — is prime material for the final Individual Knowledge Quiz, and the one numeric Week-1 tool, Multicriteria Decision Analysis, seeds the option-selection judgement used later in scope and methods.
What this chapter covers
- 01The PMBOK definition of a project: a temporary endeavour creating a unique product, service or result — and project vs operations
- 02The project economy: change is realised only through projects; managing change is the core PM challenge
- 03The five PMBOK process groups: Initiating, Planning, Executing, Monitoring & Controlling, Closing
- 04The lifecycle as a level-of-effort curve — effort ramps in Planning, peaks in Executing, tapers in Closing
- 05What happens in Initiation (Weeks 1–2): define scope and objectives, identify stakeholders, appoint the PM, develop and authorise the charter
- 06PMBOK vocabulary: Methodology vs Technique vs Tool (the course's "Methods" = Tools & Techniques)
- 07Multicriteria Decision Analysis (MCDA): weighted-score selection Sᵢ = Σ wⱼ·sᵢⱼ
- 08The 10 PMBOK knowledge areas and the C3PE five (Stakeholders, Scope, Risk, Schedule, Cost)
Multicriteria Decision Analysis: rank three options by weighted score
- +1Check the method. The weights sum to 0.5 + 0.3 + 0.2 = 1.0 (valid). For each option, multiply each criterion score by its weight and sum across criteria: Sᵢ = 0.5·(Cost) + 0.3·(Reliability) + 0.2·(Speed).
- +1Option A = 0.5·6 + 0.3·8 + 0.2·4 = 3.0 + 2.4 + 0.8 = 6.2.
- +1Option B = 0.5·8 + 0.3·5 + 0.2·7 = 4.0 + 1.5 + 1.4 = 6.9. Option C = 0.5·5 + 0.3·9 + 0.2·6 = 2.5 + 2.7 + 1.2 = 6.4.
- +1Rank by Sᵢ: B (6.9) > C (6.4) > A (6.2), so choose B. Sensitivity: B leads C by only 0.5, and B's win rests on its high Cost score under the heavy 0.5 Cost weight — if the Cost weight fell to about 0.3, C's superior reliability would overtake it, so the decision is weight-sensitive and worth a second look.
Key terms
- Temporary endeavour
- The first half of the PMBOK project definition: a project has a definite start and finish and ends when its objectives are met (or it is terminated), unlike ongoing operations.
- Process group
- One of the five PMBOK groupings of project activity — Initiating, Planning, Executing, Monitoring & Controlling, Closing — that overlap in time along the level-of-effort curve rather than running as strict sequential phases.
- Initiating
- The process group that starts a project or phase: defining scope and objectives, identifying stakeholders, appointing the project manager and developing the Project Charter to seek authorisation (the focus of Weeks 1–2).
- Methodology / Technique / Tool
- PMBOK vocabulary: a Methodology is a whole system of practices an organisation applies across projects; a Technique is a defined repeatable procedure (e.g. Earned Value Analysis); a Tool is a tangible artefact or software used within a procedure. This course calls Tools & Techniques "Methods".
- Multicriteria Decision Analysis (MCDA)
- A decision Tool that scores each option against weighted criteria and ranks by the weighted total Sᵢ = Σⱼ wⱼ·sᵢⱼ, where the weights normally sum to 1; the option with the highest score is preferred.
- Knowledge area
- One of the ten PMBOK knowledge areas (Integration, Scope, Schedule, Cost, Quality, Resource, Communications, Risk, Procurement, Stakeholder). GSOE9820's C3PE framework emphasises five — Stakeholders, Scope, Risk, Schedule, Cost — plus Communications and Resources for the full PMP.
Project Fundamentals and the Project Lifecycle FAQ
What is the difference between a project and operations?
A project is a temporary endeavour that creates a unique result — it has a definite start and finish and ends when its objectives are met. Operations are ongoing and repetitive (running a plant, a payroll, a service). The exam-relevant point is that organisations change only through projects, so project management is the discipline of delivering change on purpose.
Do the five process groups happen one after another?
No. Initiating, Planning, Executing, Monitoring & Controlling and Closing overlap along the level-of-effort curve rather than running as strict sequential phases — Planning effort ramps up early, Executing peaks in the middle, and Monitoring & Controlling runs in parallel across the whole lifecycle. A common quiz trap is to treat them as a rigid waterfall; they are groupings of activity, not fixed dates.
How is Week-1 material tested in GSOE9820?
Mostly as recall in the final Individual Knowledge Quiz: naming the process groups, matching an activity description to its group, stating the project definition, and distinguishing Methodology/Technique/Tool. The one calculable Week-1 item is the MCDA weighted score, and option-selection reasoning reappears when you justify scope and method choices in the PMP and interview.
Can Sia help me learn the PMBOK process groups?
Yes — Sia can quiz you on the five process groups and their activities, explain why they overlap on the level-of-effort curve, and walk an MCDA weighted-score calculation one step at a time, checking your working. Use it to rehearse recall for the Knowledge Quiz; it does not sit the quiz for you, and the UNSW academic-integrity policy applies.
Exam move
Lock in the vocabulary early, because it recurs in every later chapter and is easy quiz marks. Be able to recite the project definition, name the five process groups in order and say what each does, and place them on the level-of-effort curve (Planning ramps, Executing peaks, Closing tapers). Make one flashcard for Methodology vs Technique vs Tool with a worked example of each. Practise the MCDA calculation until it is automatic — normalise the weights, score, multiply, sum, rank, then add a sensitivity sentence — because the same weighted-choice logic supports later option decisions. Map the ten PMBOK knowledge areas onto the C3PE five plus Communications and Resources so you can see how Week 1 previews the whole PMP. If a distinction will not stick, ask Sia to test you on it; steady recall here protects your WAM later.
