Calculate Rework in Sprint-related work

Option 1:

Total number of employees working in 2 week sprint for small size team = 8

Defect fixing effort = no of persons*working hours per day*defects fixed per hour=8*8*2 = 128

Assume we received 100 defects

Rework effort = total defects/defect fixing effort=100/128 = 0.78 days per person.

Option 2:

Rework (%) = (total number of rework effort per sprint ÷ total number of effort per sprint) × 100%

total number of rework effort per sprint = 64 hours

total number of effort per sprint = no of person * working hours per day * number of spirt days

total number of effort per sprint = 8 * 8 * 10 = 640 hours

Rework (%) = (64 ÷ 640) × 100% = 10 %

Daily Agile Scrum stand-up meeting guidelines

Followers of the Scrum method of project management will typically start their day with a " stand-up meeting ". In short, this is a quick daily meeting (30 minutes or less) where the participants share the answers to the three questions with each other: • What did I accomplish yesterday? • What will I do today? • What obstacles are impeding my progress? Some people are talkative and tend to wander off into Story Telling . Some people want to engage in Problem Solving immediately after hearing a problem. Meetings that take too long tend to have low energy and participants not directly related to a long discussion will tend to be distracted. These are the minimum number of questions that satisfy the goals of daily stand-ups. Other topics of discussion (e.g., design discussions, gossip, etc.) should be deferred until after the meeting. Here are few tips for running a smooth daily meeting: • Everyone should literally stand-up and no one should sit down ...

Certified Enterprise Architect Professional (CEAP) - Module 4 - Architecture Precursors

Architecture Precursors: Precursors to modern Enterprise Architecture (EA) include early frameworks like IBM's Business Systems Planning (BSP), which focused on aligning business strategy with information systems, as well as other Information Systems (IS) architecture methodologies that emerged in the 1970s and 80s, emphasizing the connection between business processes and IT systems, laying the groundwork for the holistic view of an organization that EA represents today; the "Master Plan for Information Systems" by Evans and Hague is also considered a foundational concept in this area. Drivers: internal / external pressure enforce to change the system Aims & Directives: Aims: Goals Objectives Requirements Directives: Principles (example: Principles can be associated with business, data, applications, infrastructure, or security) Policies (example: Members of the public have minimal access to data) Business Rules (example: A rule directs and restricts a procedure)
