• Identify the need


  Objectives are set for what the data analysis will hope to achieve. Aims must be clear and well defined.
• Define the scope


  Restrictions of the project are defined, including factors such as budget, content, detail, timescales (deadlines) and any further constraints.
• Identify potential sources


  A wide range of sources for the potential information are identified, ensuring that it is unbiased and covers the objectives.
• Source and select information


  Information is gathered from the identified sources, and any unsuitable data is excluded so that results are not unreliable.
• Select the most appropriate tools


  The most appropriate data analysis tool for the project is selected, such as charts, graphs, regression analysis, or trend analysis.
• Process and analyse data


  Data is inputted into software such as spreadsheets or databases to further analyse, and patterns or trends are discovered.
• Record and store information


  Findings are written into a report, with statistical evidence generated from the analysis.
• Share results


  The report is shared with stakeholders, such as through a typed document, email, or website post.
