Responding to CARS is voluntary. The results presented here are from a self-selecting sample of government analysts. Because respondents are self-selecting, the results we present reflect the views of the analysts who participated.
For more detail, see the data collection page.
We asked all respondents if they had any coding experience, inside or outside of work. Of 99 respondents, 96% reported having coding experience. We asked respondents with coding experience “In your current role, how often do you write code to complete your work objectives?”
| In your current role, how often do you write code to complete your work objectives? | Percentage |
|---|---|
| Never | 1.1% |
| Rarely | 2.1% |
| Sometimes | 14.7% |
| Regularly | 51.6% |
| Always | 30.5% |

We asked respondents who reported writing code at work how frequently they write different forms of documentation when programming in their current role.
Embedded documentation is one of the components which make up a RAP minimum viable product. Documentation is important to help others be clear on how to use the product and what the code is intended to do.

We asked respondents about their knowledge of and opinions on reproducible analytical pipelines (RAP). RAP refers to the use of practices from software engineering to make analysis more reproducible. These practices build on the advantages of writing analysis as code by ensuring increased quality, trust, efficiency, business continuity and knowledge management.
The RAP champions are a network of analysts across government who promote and support RAP development in their departments. Please contact the analysis standards and pipelines team for any enquiries about RAP or the champions network.
The Analysis Function RAP strategy was released in June 2022 and sets out plans for adopting RAP across government.
We asked all respondents if they had heard anything about reproducible analytical pipelines (RAPs).
We asked respondents who had heard of RAP whether they agreed with a series of statements.
| Statement | Strongly Disagree (%) | Disagree (%) | Neutral (%) | Agree (%) | Strongly Agree (%) |
|---|---|---|---|---|---|
| I think it is important to implement RAP in my work | 0% | 2.2% | 5.5% | 28.6% | 63.7% |
| I have the resources I need to help me implement RAP in my work | 4.4% | 15.4% | 16.5% | 37.4% | 26.4% |
| I am currently implementing RAP in my work | 5.5% | 12.1% | 13.2% | 36.3% | 33% |
| My department values RAP | 6.6% | 6.6% | 22% | 33% | 31.9% |
| Sample size = 91 |
In this section we present RAP components and RAP scores.
For each RAP component a percent positive was calculated. Positive responses were recorded where an answer of “regularly” or “all the time” was given. For documentation, a positive response was recorded if both code comments and README files questions received positive responses. For the continuous integration and dependency management components, responses of “yes” were recorded as positive.
“Basic” components are the components which make up the RAP MVP. “Advanced” components are components which help improve reproducibility, but are not considered part of the minimum standard.
| RAP component | Type | Percentage of analysts who code in their work |
|---|---|---|
| Use open source software | Basic | 91.5% |
| Version control | Basic | 64.9% |
| Peer review | Basic | 63.8% |
| Work to quality standards | Basic | 61.7% |
| Create project README | Basic | 55.3% |
| Open source own code | Basic | 27.7% |
| Manually test code | Advanced | 84% |
| Write functions | Advanced | 68.1% |
| Use control flow | Advanced | 66% |
| Follow code style guidelines | Advanced | 59.6% |
| Use configuration files | Advanced | 58.5% |
| Document functions | Advanced | 50% |
| Document dependencies | Advanced | 40.4% |
