A lot will depend on your objective in doing the analysis, but viewing the data graphically is usually a good place to begin. If the data is generated by a process, plot the data as a time series in the order it was generated. Look at the shape using a histogram. Stratify the data using dot plots or box plots. Use a scatter plot for input vs. output data.
Why do you need to write a statistical procedure? There are many great statistical references out there - why do you need to specify specific approaches for your organization?
Who is your audience? What kind of statistics does your company use now? What do you want them to use?
How proficient and experienced are you at statistical analysis? What methods?

As I stated previously, a lot depends on your objective. There is no universal path that fits all situations. Read What is Data Exploration and its process? for a high-level explanation of exploratory data analysis. Some very basic steps include:
- Data Collection: Data exploration commences with collecting data. This includes determination of an appropriate sample size and the collection of potential independent/dependent and stratification variables.
- Data Cleaning: Integral to this process is the rectification of outliers, inconsistent data points, and addressing missing values, all of which are vital for ensuring the reliability of subsequent analyses. This step involves employing methodologies like standardizing data formats, identifying outliers, and imputing missing values.
- Exploratory Data Analysis (EDA): This phase involves the application of graphical tools such as box plots, scatter plots, histograms, and distribution plots. Additionally, correlation matrices and descriptive statistics are utilized to uncover links, patterns, and trends within the data.
yep, details matter...
