Agile Methodology Interview Questions and Answers

Answer: Agile methodology is an alternative to traditional project management, typically used in software development. It helps teams respond to unpredictability through incremental, iterative work cadences, known as sprints. Agile methodologies are an alternative to waterfall, or traditional sequential development.

Answer: Scrum is the most popular way of introducing Agility due to its simplicity and flexibility. Because of this popularity, many organizations claim to be “doing Scrum” but aren’t doing anything close to Scrum’s actual definition. Scrum emphasizes empirical feedback, team self management, and striving to build properly tested product increments within short iterations. Doing Scrum as it’s actually defined usually comes into conflict with existing habits at established non-Agile organizations. Scrum has only three roles: Product Owner, Team, and Scrum Master. These are described in detail by the Scrum Training Series....

Answer: In 1970, Dr. Winston Royce presented a paper entitled “Managing the Development of Large Software Systems,” which criticized sequential development. He asserted that software should not be developed like an automobile on an assembly line, in which each piece is added in sequential phases. In such sequential phases, every phase of the project must be completed before the next phase can begin. Dr. Royce recommended against the phase based approach in which developers first gather all of a project’s requirements, then complete all of its architecture and design, then write all of the code, and so on. Royce specifically objected...

Answer: Agile development methodology provides opportunities to assess the direction of a project throughout the development lifecycle. This is achieved through regular cadences of work, known as sprints or iterations, at the end of which teams must present a potentially shippable product increment. By focusing on the repetition of abbreviated work cycles as well as the functional product they yield, agile methodology is described as “iterative” and “incremental.” In waterfall, development teams only have one chance to get each aspect of a project right. In an agile paradigm, every aspect of development — requirements, d...

Answer: Unlike the WaterFall method , Agile Testing can begin at the start of the project with continuous integration between development and testing. Agile Testing is not sequential (in the sense its executed only after coding phase) but continuous. Agile team works as single team towards a common objective of achieving Quality .Agile Testing has shorter time frames called iterations (say from One to Four weeks ). This methodology is also called release or delivery driven approach since it gives better prediction on the workable products in short duration of time.

Answer: Metrics that can be collected for effective usage of Agile is: Drag Factor Effort in hours which do not contribute to sprint goal Drag factor can be improved by reducing number of shared resources, reducing the amount of non-contributing work New estimates can be increased by percentage of drag factor -New estimate = (Old estimate+drag factor) VelocityNo of Unit Tests added Amount of backlog converted to shippable functionality of sprint Time taken to complete daily build Bugs detected in an iteration or in previous iterations Production defect leakage

Answer: Onsite-offshore model   In an outsourcing engagement, the onsite-offshore hybrid model is the most popular softwaredevelopment model offered by service vendors to their clients. In this model, the outsourcingwork is distributed between the onsite center (usually the client location) and service provider’s offshore development center. Usually,20-30% of the work is done at the onsitecenter that includes requirement gathering,planning and initial designing, co-ordination,issue resolution, deployment and support. The actual development and testing of thesoftware is done at the offshore center, based on the requirements provided to them...

Answer: Service providers have attempted to deal with these problems by putting strong formalprocesses around the software development life cycle (SDLC). Most software service providersfollow the processes as suggested by CMMi model.These processes require creation of several artifacts such as comprehensive plans,requirement specifications, design models, test cases, bug reports etc. The processes demandreview and formal sign-off of all documents be fore moving into the next phase of SDLC. A huge metrics collection is also required to determine productivity, schedule slippage,efforts/budget overrun, and defects data. These metrics are useful in bring...

Answer: Product backlog: It contains a list of all desired features and is owned by the product owner. Sprint backlog: It is a subset of the product backlog owned by development team and commits to deliver it in a sprint. It is created in Sprint Planning Meeting

Answer: Continuous Integration is important for Agile for following reasons. It helps to maintain release schedule on time by detecting bugs or integration errors Due to frequent agile code delivery usually every sprint of 2-3 weeks, stable quality of build is a must and continuous integration ensures that In helps to maintain the quality and bug free state of code-base Continuous integration helps to check the impact of work on branches to the main trunk if development work is going on branches using automatic building and merging function

Answer: Challenges involved in Agile Software development includes It requires more testing and customers involvement It impacts management more than developers Each feature needs to be completed before moving on to the next All the code has to work fine to ensure application is in working state More planning is required

Answer: Before using Agile methodology, you must ask following questions Is functionality split-able Is customer available Are requirements flexible Is it really time constrained Is team skilled enough

Answer: The following are some essential agile matrices Speed – that is used to track the development of a missionThe sprint burndown matric – this facilitates to track the paintings completed with the dash.The priority of the paintingsWork class allocation – this metric allows to get an concept approximately the priority of the work and paintings category allocation.The cumulative go with the flow diagram – the uniform glide of work may be checked thought this diagram of cumulative waft. Right here the x-axis represents time and the y-axis stands for the variety of attempt.Defect removal attention – this enables to supp...

Answer: Some of the famous agile methodologies are: ScrumLean software improvement and excessive programming (xp)Feature-driven development (fdd)Crystal techniqueDsdm (dynamic software development approach)

Answer: Scrum and intense programming both comply with iterations which can be known as sprints. But, the sprints in a scrum technique last as long as  weeks to 1 month lengthy while in excessive programming (xp) crew the iteration lasts for one or two weeks. Intense programming is extra bendy than scrum as scrum does not allow any alternate in during iterations.

Answer: Economic modeling is a quantitative evaluation commonly used for both asset pricing or preferred company finance. It's miles the manner wherein a organization’s fees and profits are considered (typically into spreadsheets) to expect the impact of these days’s choices in the destiny. The economic model also seems to be a totally impactful tool for the subsequent obligations: Estimate the valuation of any enterpriseEvaluate competitionStrategic planningTrying out unique eventualitiesPrice range planning and allocationDegree the impacts of any changes in monetary guidelines

Answer: There are two examples – A organisation that is selling off stock but delaying payables will display fantastic cash glide for some time even though it is in problemA corporation has sturdy sales for the duration, however future forecasts show that revenues will decline
