Working notes for building a risk assessment process using the Evaluator toolkit. This vignette details the basic flow used at some organizations to maintain reproducability of inputs and results. While other technologies and solutions may be employed, this workflow is intended to be easy to implement for users familiar with source control principles.

Starting from Scratch

• Create a starting Evaluator working directory via create_templates()
• Customize the domains used in your organization by editing the domains.csv file to include the domains (and their abbreviations) which are appropriate for your risk domain and organization.
• Edit the survey.xlsx spreadsheet to include the risk scenarios and the threats for each scenario which you wish to monitor on an ongoing basis.
• Create a source code repository (such as a GitHub for Enterprise repo) for your ongoing risk analysis work.
• Add a tag to designate the just committed files (without analysis) as your reference documentation.

Performing an Analysis

• Meet with subject matter experts for each domain and walk through each scenario and threat source.
• Record answers in the survey.xlsx spreadsheet.
• Run the analysis as detailed in the usage vignette.
• Commit the inputs and results to your source code repository.
• Add a tag to reflect the state as of a certain point in time (i.e. FY18 Q1)

What to Store

If using the sample workflow, you will have two subdirectories located under a parent evaluator directory in your home folder. inputs contains the qualitative scenarios and input data files, while results stores the simulation results, including the summarized data files. Both directories together represent an analysis snapshot.

Quick Start Script

When using create_templates() a run_analysis.R file will be placed at the base of the evaluator directory. A sample ultra-quick workflow looks like:

1. Run evaluator::create_templates("~/evaluator")
2. Edit the inputs for your situation.
3. Run the quick start script with code like the following:

base_dir <- "~/evaluator"
source("~/evaluator/run_analysis.R")
