1 Data collection

The first step to ensure data accuracy is to collect reliable and relevant data from credible sources. You should verify the source, date, and methodology of the data, and avoid using outdated, incomplete, or biased data. You should also use consistent and standardized formats and units for the data, and document the data sources and definitions for future reference.

2 Data validation

The second step to ensure data accuracy is to validate the data before using it for analysis. You should check the data for errors, inconsistencies, outliers, and missing values, and use appropriate methods to correct, remove, or impute them. You should also compare the data with other sources or benchmarks to confirm its accuracy and reasonableness. You can use tools such as Excel, Python, or R to perform data validation tasks.

3 Data analysis

The third step to ensure data accuracy is to conduct rigorous and objective data analysis. You should use appropriate and robust techniques and models to analyze the data, and avoid using assumptions or biases that may skew the results. You should also test the sensitivity and validity of the analysis, and use visualizations and summaries to communicate the findings clearly and accurately.

The fourth step to ensure data accuracy is to review the data and the analysis before presenting or reporting them. You should check the data and the analysis for errors, inconsistencies, or gaps, and use feedback and peer review to improve them. You should also ensure that the data and the analysis are aligned with the purpose and scope of the project, and that they address the key questions and objectives.

Tenha um bom sistema, estabele?a bons processos e fluxos de informa??o. Treine as pessoas que devem registrar as informa??es para que fa?am de forma adequada. Se acertar na entrada, no início, mantendo organizado a partir daí, fica mais fácil lidar com os dados sem tanto trabalho depois.

5 Data security

The fifth step to ensure data accuracy is to protect the data from unauthorized access, modification, or loss. You should use encryption, passwords, backups, and access control to secure the data, and follow the relevant laws and regulations regarding data privacy and ethics. You should also update and maintain the data regularly, and delete or archive the data when no longer needed.

6 Data education

The sixth step to ensure data accuracy is to educate yourself and others on the importance and best practices of data accuracy. You should learn and apply the skills and knowledge related to data collection, validation, analysis, review, and security, and keep up with the latest trends and developments in the field. You should also share and promote the value and benefits of data accuracy within your organization and with your stakeholders.

I′d like to highlight 3 steps when dealing with data for financial planning: Step 1 - Exploratory Analysis. Understand the data, trends and outliers. Plot into tables, graphs, summarize, break it all down. Step 2 - About trends and outliers, start creating hypotheses. Step 3 - Explore the reasons (root-cause) that can be affecting or creating the variations to be explained. And again, break it down. All Management / C-Level love bridges! Start from the last period, or from the average of what you’re trying to explain. Then quantify the reasons for the total variation. Avoid having more than 3-4 blocks. If you have many, group them. List the insights, ordered by priority of action. And then start building your story!
