Scrum Framework

Agile is a popular software development methodology use today. Scrum and eXtreme Programing (XP) are two types of agile methodology. Sutherland (in Lacey 2012) states that 75% of the agile software development use Scrum framework and around 17% of the scrum team use XP engineering practices. Scrum framework looks extremely simple however it is found to be hard to implement effectively.

Scrum is a lightweight and simple process framework used for developing complex products. It is not a process, methodology or engineering practices.

Scrum's 5 Core Values


  • Focus
  • Respect 
  • Commitment 
  • Courage 
  • Openess 

Scrum Project Roles

  • Scrum master - The scrum master works as a facilitator of the team. He ensures that the team is functioning as expected. 
  • Product owner - The product owners is the person who drives the project. 
  • Scrum Team - Team who actually do the development. 

Scrum Artifacts

  • Product backlog - This artifact consists of all the select requirements that need to be met. The requirements are sorted according to its priority. 
  • Sprint backlog - The requirements stated in the product backlog is grouped into Sprints so that it can be completed in 2-4 weeks. This artifact consists of the requirements that is to be met on a particular sprint
  • Burndown chart - This chart provides the current status snapshot during a scrum project. It shows amount of work that needs to be completed and the time remaining. In 2011, it was agreed that burndown charts are not mandatory artifacts.

Scrum Meeting

  • Release planning - This meeting is carried out before starting a sprint. For that sprint that is n weeks long requires n x 2 hrs of release planning. 
  • Daily Scrum meeting - This is 15 minute stand-up meeting that is carried out daily at the start of day. The purpose of the meeting is to facilitate free communication and understandings among team members. Three important questions discussed by each team members are:
    • - What I did yesterday?
    • - What I will do today?
    • - What are possible obstacles that I face today?
  • Sprint Review - This meeting is conducted after the completion of a sprint. In this meeting the client feedback is the most important. In other words, client is expected to approve the product released. 
  • Spring Retrospective - This meeting is more internal to the Scrum team and product owner is kept out of this meeting. Possible questions addressed in this meeting are:
    • - What went well in last sprint?
    • - What needs improvement?

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

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
