IT301 Unit 5 duration estimates example

Project Management I Purdue University Global Free custom sample in 24 to 48h

Fourteen overnight shifts for the fleet installation, 27.5 working days for sign permits, ten days to configure the prediction server: every figure in this IT301 Unit 5 duration estimates sample arrives with the method that produced it. Sixty-four activities drawn from the bus system's work packages are estimated by four different techniques, each chosen for the kind of uncertainty involved.

What this page holds

Each of sixty-four durations estimated for IT301 Unit 5 names the method behind it, whether parametric, analogous, three-point or bottom-up, with assumptions logged beside the figures. Searches like "it 301 unit 5 assignment example", "it301 unit 5 sample" and "it301 unit 5 example" land here.

What a finished IT301 Unit 5 duration estimates looks like

A table of 64 activities, grouped under their WBS codes, with columns for activity, method, effort hours, assigned resources, duration in working days, basis of estimate and confidence. Four methods appear. Fleet installation is parametric: 42 buses at three per overnight shift gives 14 shifts. Pilot installation is analogous, adjusted from the vendor's work at a comparable agency. Sign permitting uses a three-point estimate with optimistic 15, most likely 25 and pessimistic 50 days, giving a beta mean of 27.5 and a standard deviation near 5.8. Operator training is bottom-up: 110 operators in groups of twelve require ten sessions. One worked example separates effort from duration, showing 60 hours of configuration spread across ten working days at six productive hours a day. An assumptions log closes the document.

How a IT301 Unit 5 example is structured

Estimating starts from activities rather than packages. The document first converts each work package into the activities needed to produce it, so every duration traces to the WBS code above it. Methods are then matched to uncertainty: parametric where a reliable unit rate exists, analogous where only a similar past job does, three-point where outcomes depend on an outside party, and bottom-up where detail is available now. Each formula is shown once in full and then applied, so a grader can check the arithmetic without redoing the table. Effort and duration are kept in separate columns throughout. Activities late in the project, such as launch support, are estimated at lower precision and flagged for refinement under rolling wave planning. Individual estimates carry no hidden padding; uncertainty is handled later through reserves, and a paragraph explains that choice.

Activities traced to packages

Each of the sixty-four activities sits under the WBS code it serves, so no duration floats free of the structure built in the previous unit.

Method matched to uncertainty

Parametric, analogous, three-point and bottom-up, each assigned where its assumptions hold and named in its own column beside the figure.

The permit estimate worked out

Optimistic, most likely and pessimistic values combined with the beta weighting, then a standard deviation reported to show how wide the uncertainty runs.

Effort kept apart from duration

Hours of work and working days elapsed sit in separate columns, with one worked conversion showing how availability turns one into the other.

Assumptions and refinement

A logged assumption behind every rate, and late activities flagged for re-estimating once earlier work reveals more.

Where marks go in IT301 Unit 5

Numbers without reasons sink more estimating submissions than wrong numbers do. A duration column with no basis of estimate cannot be assessed, however plausible the figures look. Effort and duration confused, forty hours of work entered as a forty-day activity, is the most common technical error. Three-point estimates labeled PERT but computed as a simple average of three numbers mix up the triangular and beta formulas. Padding every activity quietly, rather than managing uncertainty through reserves, draws comments in sections that cover reserve analysis. Estimates attached to summary elements instead of activities leave nothing for scheduling to link. Calendar days and working days mixed in one table, missing assumptions, and a single method applied to everything regardless of uncertainty are the remaining frequent notes.

IT301 Unit 5 questions, answered

What is the difference between effort and duration?

Effort is the amount of work, measured in person-hours. Duration is the elapsed working time from start to finish, measured in working days. Sixty hours of effort might take ten days if one analyst gives it six hours a day, or five days with two analysts. Schedules run on duration, while budgets usually run on effort.

Which three-point formula should I use?

It depends on what your course text teaches. The triangular version averages the three values equally; the beta or PERT version weights the most likely value four times and divides by six. They give different answers, so name the formula used. The sample follows whichever your instructions specify, and states the formula before applying it.

Is there a seminar reflection around Unit 5 too?

In many sections, yes: a seminar or its written alternative near the estimating unit, often discussing why estimates go wrong in practice. It is graded separately from the estimates themselves. If your section pairs them, send both prompts and each can be modeled on its own terms, the reflection written as a short first-person piece.
