Requirements Engineering

Requirements engineering consists of Requirements development and Requirements management. In Requirements development, following activities are carried out:

Requirements elicitation,
Requirements documentation and
Requirements validation and negotiation.

Requirements management is defined in many different ways, according to Pohl and Rupp (2016), requirements management is carried out along or in parallel with requirements development activities to prioritize, trace and manage changes to the requirements.

Reasons for Bad Requirement
According to Pohl and Rupp (2016), requirements can be incomplete when stakeholders omit some requirements thinking that it is well known and that it is not necessary to state it explicitly. This issue arises due to differences in knowledge and experiences of stakeholders and project team.

CUMIPMT and CUMPRINC function

CUMIPMT Cumulative interest payment function allows you to calculate the interest paid for a loan or from an investment from period A to period B. When getting a loan, CUMIPMT function can be used to calculate the total amount of interest paid in the first five months or from period 12 to period 20. A period can be a month, a week or two week. Loan Amount : 350,000.00 APR: 4.5% Down payment: 0.00 Years: 25 Payment per year: 12 From the above data, we can calculate the following: No of Period: 25 × 12 = 300 Periodic Rate: 4.5/12 = 0.375% Here is how you will substitute these values into the function. = CUMIPMT (periodic rate, No of period, vehicle price, start period, end period, ) = CUMIPMT (0.375, 300, 350000, 1, 5, 0) In an excel worksheet, we use cell address instead of actual values as shown below: Here is the formula view of the worksheet: CUMPRINC Another related function is CUMPRINC. CUMPRINC function is used to calculate cumul

Excel PMT Function

PMT function is very useful for calculating monthly payment required to payback a loan or mortgage at a fixed rate. This function require a minimum of three inputs, periodic rate, number of periods, present value or the loan amount. Here is a simple example. Home Loan: 350,000.00 Interest rate: 4.5% Number of years to repay the loan: 25 Note: To calculate monthly payment, we need to find the monthly rate and number of months as shown above. Then it is simply a matter of substituting the values into the payment function, as shown in the formula view below.

BCG's Brand Advocacy Index

The Boston Consulting Group's (BCG) Brand Advocacy Index (BAI) is a metric developed to help companies measure the degree of customer advocacy for their brands. BAI focuses on the likelihood of customers to recommend a brand to others, which is a powerful indicator of brand strength and customer loyalty. Unlike other customer satisfaction or loyalty metrics, BAI emphasizes the importance of customer referrals and word-of-mouth marketing. BAI is calculated based on a survey where customers are asked about their willingness to recommend a brand to their friends, family, or colleagues. The responses are then used to compute a score, which ranges from -100 to 100. A higher BAI score indicates that a brand has more advocates who are likely to recommend the brand to others, while a lower score suggests that the brand has fewer advocates or even a higher number of detractors. BCG's research has shown that companies with higher BAI scores tend to experience higher growth rates and bett
