Getting started with the `rarr` Package

Introduction

Risk assessment is a common component to the project management cycle. The purpose of this package is to assist in the wrangling and presentation of risk assessment data generated throughout the project management cycle. The products created by the functions in this package can be integrated into an R [bookdown package] report to create a static webpage to communicate risk during a given project.

Install

To install the rarr package, install from GitHub using the remotes package:

remotes::install_github(repo = "MVR-GIS/rarr@*release")

Add data

Load the package:

library(rarr)

Load data from data source (here we reference internal test data):

risk<-rarr::db_risk

Wrangle Data

Once the data has been loaded, proceed to the cleaning and wrangle functions. The “risk” table will be used as an example.

risk_active <- remove_inactive_records(db_risk)
risk <- wrangle_risk(db_risk)

Related risk tables must also be wrangled to be able to create the timeline and network analysis figures.

rel_action_action<-rarr::wrangle_rel_action_action(db_rel_action_action)

rel_dec_action <- rarr::wrangle_rel_dec_action(db_rel_dec_action)

rel_dec_dec<- rarr::wrangle_rel_dec_dec(db_rel_dec_dec)

Presenting Data

Once the data has been wrangled, it can then be passed into a variety of filters to create tables and figures as seen in BRIP RARR

Some of these processes involve the table functions from the rarr package and the figure building functions

Wrangled output undergoes a filter

risk_high <- risk %>%
   dplyr::filter(COST_RISK == "HIGH" | SCHEDULE_RISK == "High" | EFFICACY_RISK == "High")

Example of creating charts with wrangled risk data

rarr::risk_pies(risk_high)

Example of using a table function to present wrangled risk data

rarr::risk_register_table(risk_high)

Number	Description	Strategy	Efficacy	Cost	Schedule
Contract Acquisition Risks
CA-003	Larger contracts may be broken into multiple contracts.	Accept	Moderate	High	High
Environment
EN-001	The assumption made during the feasibility study was the site could be used for construction with some remediation. Environmental site investigation may result in unusable site or high cost. This risk pertains to required real estate footprint on the RDB.	Accept & Mitigate	Low	Moderate	High
Non-Regulatory
L-001	If required land rights are not provided by a willing seller, condemnation and/or quit take authority could take longer to accomplish than the scope and schedule of this project may allow.	Accept	Low	High	High
L-002	Costs for project land acquisition could exceed what the state of Illinois is willing to pay for the property.	Accept	Low	High	High
L-003	Costs for project land rights hazardous waste remediation could exceed what the state of Illinois is willing to spend on remediation and/or could take longer than scope of project to complete.	Accept & Mitigate	Low	High	High
Project & Program Mgmt
PMM-003	Eventual operation, maintenance, repair, rehabilitation, and replacement responsibilities should be based on the expected project life of 50-years rather than a commitment in perpetuity. (PPA issue)	Accept & Mitigate	High	Moderate	Moderate
PPM-001	Concern that the PPA cannot be negotiated and signed on time.	Accept	High	Moderate	High
PPM-002	Lack of efficient funding in PED could delay design.	Accept & Transfer	High	Moderate	High
Real Estate
RE-001	Right descending bank may not be available for use.	Accept & Mitigate	Low	Moderate	High
Technical Risks
TR-006g	Navigation delays during construction	Accept & Mitigate	Low	Moderate	High
TR-008	There may be problems with achieving the desired effectiveness of the entire ANS control system.	Accept & Mitigate	High	Moderate	Low
TR-009d	Single source for speakers, sole proprietor	Accept & Mitigate	Low	Low	High
TR-009f	Operability, maintainability, sustainability. This risk is due to lifecycle costs with the speakers over time.	Accept	High	Low	Low
TR-021	Velocity can pull floaters or small fish through barriers when barge traffic is active.	Accept & Transfer	High	Low	Low
