CAPSTONE | 6 local-complete, 3 partial | IBM learning capstone

HealthFirst Business Analyst Capstone

Nine connected labs for a simulated hospital, from requirements and stakeholder planning through data analysis, an interactive Excel dashboard and risk mitigation.

Seven separate Excel workbooks and PDF/DOCX report pairs cover requirements, stakeholders, scope, analysis, dashboards and risk.
The analysis workbook has four native PivotTables, six slicers and four charts; the dashboard has four pivots, six slicers and two charts.
A desktop Excel check changed the appointment KPI from 200 to 38 with the Cardiology slicer and restored it on reset. The dynamic risk matrix recalculated after an R01 change.
A two-page index maps all nine labs, their evidence, relative file links and the three remaining platform/notation requirements.

Six labs are complete locally with review open. Local SVG diagrams do not fulfil the Lucidchart/Visio requirement; BPMN conformance is unvalidated, and the Cognos/Looker exercise is unfulfilled. Simulated data; no hospital sign-off, executed UAT, deployment or measured benefit.

Lab Progress

Lab	Progress and next steps
1. Requirements and RTM	Local complete; review open
2. Stakeholder analysis	Local complete; review open
3. Scope and WBS	Local complete; review open
4. As-Is and To-Be models	Partial: editable SVG models; Lucidchart/Visio requirement unfulfilled
5. Process maps and swimlanes	Partial: role-lane diagrams; BPMN conformance unvalidated
6. Data cleaning and analysis	Local complete; review open
7. Dashboard	Partial: interactive Excel dashboard; Cognos/Looker exercise unfulfilled
8. Risk register and SWOT	Local complete; review open
9. Risk matrix and mitigation	Local complete; review open

I developed this simulated capstone using fictional data and profiles. Six labs are complete locally with review open; three retain the platform or notation requirements listed above. No hospital sign-off, executed UAT, deployment or measured benefit is claimed. The earlier 39-slide hospital case study uses a separate dataset.

ANALYSIS COMPLETE | Pilot proposed | DataCamp data science project

Tasty Bytes Recipe Site Traffic

A historical recipe-traffic classification analysis testing whether a product manager can select homepage recipes with at least 80% precision.

Analysed 947 recipes, including missing nutrients, servings text and eleven observed categories; documented the provisional interpretation of 373 blank traffic labels.
Separated training, validation and test data, and compared a select-all baseline, logistic regression and a random forest with validation-selected thresholds.
On held-out data, the forest selected 90 of 190 recipes; 78 were High: 86.7% precision, 47.4% coverage and 67.8% recall. The 95% Wilson precision interval was 78.1–92.2%.
Published the actual nine-page report, ten-slide presentation PDF, animated PPTX, current Google Slides and reproducible analysis files.

Historical model evaluation, not a deployed recommendation system or causal traffic/subscription lift. Blank-label meaning needs confirmation; shadow mode and a randomized pilot are proposed. The confidence interval extends below the 80% target.
