Tag: Project-Management

The same project schedule network shown three times: the baseline, then the network under a scenario applied to an activity with no float, where the finish date is pushed out by eight weeks, then under a scenario applied to an activity that has four weeks of float, where the finish date does not move.

What-If Scenario Analysis

Goal What-if scenario analysis applies a named condition to the schedule and then recalculates it to measure the effect on the project's objectives. The question is …

Cumulative gains chart: the horizontal axis carries the share of the population contacted from the top of the ranking, the vertical axis the share of responses captured; the concave curve sits above the random-selection diagonal and a marker shows the cutoff retained, 50 per cent of the population for 87 per cent of the responses.

Lift chart and cumulative gains chart

Goal Both charts are built on the ordering that a per-unit score induces, a predicted probability or any rating at all, and they answer a single question: how many …

The eight stages of Kotter's change process laid out on a time axis and grouped into three phases: creating a climate for change (stages 1 to 3), engaging and enabling the organisation (stages 4 to 6), implementing and sustaining the change (stages 7 and 8). A curve follows the programme's momentum: it rises to the first wins of stage 6, then falls back at stage 7, victory declared too soon.

Kotter's change process

Goal Kotter's change process leads a transformation through eight stages to be cleared in order. The question it answers is one of sequence: in what order to commit …

Three panels linked by arrows. Decide and prepare: written, settled mandate, sponsor confirmed in person, invitees drawn from the stakeholder list, one or two sessions: internal first, then wider. Hold the session, in order: mandate and purpose first, people and roles, way of working, one working format, close. Leave with: mandate and criteria stated, responsibilities allocated, shared working rules, cadence and reporting rules, known risks listed, actions with a name and a date.

Kick-off meeting

Goal The kick-off meeting is the session where the project sponsor states the mandate in front of the team and the people involved, where the roles are settled and …

A case officer's window before and after a one-hour session: feedback from three colleagues pushes the vertical boundary to the right, self-disclosure pushes the horizontal boundary down, the open area grows on both sides with the total surface unchanged.

Johari Window

Goal The Johari window makes visible the gap between what a person knows about themselves and what the people around them observe. It was built for group dynamics …

The target profile and the observed level of a business analyst at a Lausanne health insurer, across five competencies: three bars reach the target, data analysis exceeds it by one level and negotiation with stakeholders stays one level below.

Competency framework

Goal A competency framework makes a decision about a person defensible. It writes down in advance what the role requires, competency by competency and level by …

Two residual cloud shapes for a forecasting model: on the left errors centred on zero with a constant spread, on the right a fan opening as the predicted turnover grows.

Technical Visualizations

Goal A technical visualization is a statistical chart the analysis team produces for itself, during the analysis, to test a modelling assumption. A chart built for a …

Feasible region of a two-variable production plan. The axes give the number of Standard and Connected instruments. Three constraint lines, assembly, calibration and radio modules, cut out a grey polygon. A family of parallel objective lines slides up and to the right and touches the polygon one last time at the vertex 160 Standard and 80 Connected, marked CHF 43'200.

Optimisation

Goal Optimisation answers a question of proportions: what quantities to produce, what resources to assign to which use, which mix to settle on, when the feasible …

The hypothesis test sequence, the guide's seven steps grouped into five stages, cut by a vertical barrier: on the left, what is settled before the data is collected; on the right, what is calculated afterwards.

Hypothesis Formulation and Testing

Goal Hypothesis testing settles a business claim nobody has checked: the complaint rate has fallen, this variant costs less. It turns the claim into a statement that …

Diagram showing exploratory data analysis as the gate between sourced data and two downstream techniques, hypothesis formulation and testing as well as data mining, with a return loop to the sourced data.

Exploratory Data Analysis

Goal Exploratory data analysis questions a dataset before any analytical decision and answers three questions: what data is available, what state it is in and which …

Three-branch diagram from one problem statement. The left branch, root cause analysis, descends towards candidate causes without changing the statement, down to a cause to correct. The centre branch, shaping, narrows the statement within the same context, down to a statement a method can be applied to. The right branch, reframing, moves the statement into another context, down to a non-analytical answer that becomes admissible.

Problem shaping and reframing

Goal Shaping and reframing work on the problem statement itself, at the moment when it can still change. An analysis team usually receives a problem already worded …

The ETL process in four stages: extraction pulls the data out of three source systems, with a branch between incremental and full extraction, then the staging area holds the batch and is the point a run restarts from. Transformation applies the rules declared by the data mapping; loading writes into the target repository, incrementally or by full replacement, and it produces the audit trail of the run.

Extract, Transform, and Load (ETL)

Goal ETL brings together in one repository data that several systems hold separately, each with its own format, its own coding scheme and its own update cycle. A …
