Step 3: Discover Business Objectives – This step involves understanding the business needs of the project before going deep into the project. Techniques such as SWOT analysis, benchmarking, analyzing business objectives SMART, and listing business objectives are some methods utilized for this purpose.
Step 4: Evaluate Options – This step involves identifying the options to achieve business objectives. Impact, risk, and cost-benefit analyses are used for this purpose.
Step 5: Definition of Scope – A scope refers to the development objectives of a project, determined by business goals. A document detailing the goals for each project phase is utilized for scope definition.
Step 6: Delivery Plan by Business Analyst – A business analyst document is drafted at this stage based on project scope, stakeholder availability, and project methodology. This document provides information on deliverables along with their timeline.
Step 7: Project Requirements Definition – At this step, two types of documents are employed – functional requirement document and non-functional requirement document. Based on the development methodology implemented in the project, the business analyst needs to clarify the requirements with stakeholders by interviewing them on the requirements and obtaining their sign-off.
Step 8: Support Implementation through SDLC – This technical implementation stage of the requirements involves the business analyst working with different teams. This includes coordinating with the development and testing teams to ensure that requirements are implemented as expected and adequately tested against all possible business scenarios. Additionally, they need to handle change requests that may arise from stakeholders later.
Step 9: Evaluation of Added Value by Project – This involves the ongoing evaluation of the project to determine whether the business objectives have been implemented correctly and to ensure that they meet the business needs, outcomes, and timeline.
Why is it important for a business analyst to be involved in implementing requirements?
Gaining domain knowledge and providing analytical solutions are the two major criteria of a business analyst. During the actual implementation of a requirement or use case, a business analyst can help to resolve many business strategy-related problems that may arise during the implementation stage. Moreover, they can learn from the problems that may arise, which may help them provide solutions in similar scenarios, and also help to enhance their domain knowledge.
What are the potential challenges that a business analyst may face?
Throughout the initiation to post-implementation stages of a project, a business analyst may encounter the following difficulties:

What distinguishes data profiling from data mining?
Data profiling examines individual data attributes, providing valuable information on data attributes such as data type, frequency, and length, as well as their discrete values and value ranges. On the other hand, data mining aims to identify exceptional records, analyze data clusters, and uncover sequences.
Could you define the KNN imputation method?
The KNN imputation method seeks to fill in the values of missing attributes using the attribute values that are closest to the missing attribute values. The similarity between two attribute values is calculated using a distance function.
What should a data analyst do when faced with missing or questionable data?
In such circumstances, a data analyst must:
- Utilize data analysis techniques like deletion, single imputation, and model-based methods to detect missing data.
- Create a validation report containing all information about the suspicious or missing data.
- Examine the questionable data to determine their validity.
- Replace any invalid data (if any) with an appropriate validation code.
A complete data analyst interview guide would be remiss without discussing outliers. Data analysts commonly employ this term to refer to a value that appears conspicuously divergent from a set pattern within a sample. Outliers are of two types: Univariate and Multivariate.
There are two methods that data analysts use to detect outliers:
The box plot method identifies values exceeding 1.5 times the interquartile range (IQR) from the lower or upper quartile (Q1 or Q3). Values that fall beyond this range are considered outliers.
The standard deviation method identifies values that exceed mean ± (3*standard deviation). Any value that falls beyond this range is regarded as an outlier.
