How will these factors affect our problem statement? The answer to this is the System Maps tool. It provides
                 the relationship of various factors and their impact on the project goal. The following is the system map for the
                 above scenario.
                                                                                             +

                                                                     +

                 The above system map shows the relationship of various data features with each other. The goal of the project is
                 to reduce food wastage, each element is defined to depict its impact on the goal. An arrow with a positive sign
                 shows a direct relation and the one with negative signs shows an inverse relationship with the elements.

                 For our scenario, a dataset that covers the details of all elements for making a specific dish is prepared by the
                 restaurant. The data is collected over the past 30 days through surveys as it caters to a specific restaurant only.
                 The elements are under the following heads— Quantity of dish produced per day, Quantity of unconsumed dish
                 each day, Price of the dish, Total footfall of the day, Number of fixed customers, etc.


                 Stage 3: Data Exploration
                 The next stage is data exploration, it is the stage of cleaning the acquired data. Once the data is collected, we
                 extract meaningful information from it to achieve the goal of our project. In our scenario, the goal is to develop an
                 effective system that can predict the quantity of food to be prepared by restaurants to minimise wastage.

                 The following data needs to be prepared for the same:
                    • Name of the dish.

                    • Quantity of the dish prepared every day.
                    • Unconsumed quantity of dish per day.


                 Stage 4: Data Modelling
                 After the data is explored and the dataset is ready, the next stage is data modelling. In this, the model is fed with
                 the training dataset to see if it matches the desired output. In this scenario, the Regression model is chosen.
                 Regression is a supervised learning model, which is used to predict continuous values. In our scenario the data
                 set that we shall use to train our model is a continuous data of 30 days, we can use a regression model so that
                 it can predict the next values. In this case, the model is trained for the first 20 days and then gets evaluated for
                 the rest 10 days.
