<p>Let’s say a lottery-winning donor wants to open a network of kindergartens in her rural Turkish hometown, aiming to make them affordable for local families and self-sustaining after her initial investment. She hired you as a Business Analyst consultant to lead the strategy for her mission.</p>

<p>How would you approach evaluating the feasibility of this plan, and what key factors or analyses would you consider to ensure both affordability and long-term sustainability?</p>


How would you as a consultant develop a strategy for a client's mission of building an affordable, self-sustaining kindergartens in a rural Turkish town?

Kindergarten Feasibility

Business Problem Solving

<p>You work on an artificial intelligence team at ABC Neural Inc. Your client, the New York City Transit Authority, provides an hourly feed of subway ridership data (entries and exits) for the NYC Subway system. Your task is to predict the number of riders each hour for each subway station.</p>

<p>Design and outline a solution (both functional and non-functional requirements) that takes the hourly ridership data as input and delivers predictions of hourly ridership back to the client. Predictions must be consistently updated as new data arrives, and the end product will be integrated into the client’s internal systems.</p>


Identify requirements for a machine learning model that predicts subway transit

Subway Machine Learning Model

<p>An electronics retail company tracks its sales and wants to run a performance analysis. They’re hoping to categorize sales into different groups, based on the amount of sales and the region where the sale occurred. The conditions for categorization are:</p>

<ul>
<li><strong>Standard Sales</strong>: Any sales below 2000 are considered standard, except if they occur in the <code>East</code> region, or in the month of July.</li>
<li><strong>Premium Sales</strong>: Any sales that are over or equal to 2000, or any sales in the <code>East</code> region (regardless of the amount), are considered premium, except again during the month of July.</li>
<li><strong>Promotional Sales</strong>: All sales made in the promotional period of July, regardless of the amount or region, are considered promotional.</li>
</ul>

<p>The company wants a report that sums these amounts by region to help with financial planning and bonus allocations.</p>

<p><em>Note: You may assume that table contains data only for 2023</em></p>

<p><strong>Example:</strong></p>

<p><strong>Input:</strong></p>

<p><code>sales</code> table</p>

<table>
<thead>
<tr>
<th>Column</th>
<th>Type</th>
</tr>
</thead>

<tbody>
<tr>
<td><code>sale_id</code></td>
<td>INTEGER</td>
</tr>

<tr>
<td><code>employee_id</code></td>

<tr>
<td><code>sale_amount</code></td>
<td>FLOAT</td>
</tr>

<tr>
<td><code>sale_date</code></td>
<td>DATE</td>
</tr>

<tr>
<td><code>region</code></td>
<td>TEXT</td>
</tr>
</tbody>
</table>
<p><strong>Output:</strong></p>
