What is the difference between predictive and adaptive SDLC?

The predictive approach to the SDLC is used for projects that are well understood and low risk. The adaptive approach to the SDLC is used for projects that are not well understood and are higher risk. Adaptive SDLCs are more iterative and allow the project team to adapt the project to changing circumstances.

What is the basic difference between the predictive approach and the adaptive approach?

Adaptive planning involves breaking a project into small components over an undetermined timeline to allow ultimate flexibility in directing the course of the project. Whereas the outputs from predictive planning are expected and knowable, adaptive planning may yield surprising outcomes.

What is the difference between a predictive and adaptive life cycle?

The predictive model generates a working software product quicker than the adaptive model. … It is easier to test and debug during iterations of smaller pieces than on the full product. This model allows for more flexibility, as changes to scope and requirements may be made to every increment.

What is adaptive SDLC?

Adaptive SDLC entails iterative, evolutionary and incremental methodologies which offer flexible guidelines and easy flow of work. Methodologies such as Agile are efficient in nature and enhance team collaboration. Short feedback loops lead to quick adaptation to changing requirements.

What are the characteristics of a predictive SDLC approach?

What characteristics of a project call for a predictive approach to the SDLC? Predictive: Projects are well understood—technology is well known; user requirements are well known; development methodology is well known; project team is experienced and familiar with the system; and there are few known risks.

What is a predictive life cycle?

Predictive life cycles (also known as classic or planning-focused life cycles) are those in which the scope, deadline and cost are determined as soon as possible in the project life cycle and efforts are focused on meeting the commitments established for each one of these factors.

Is waterfall predictive?

Waterfall project management is a more predictive planning strategy that utilizes specific steps and milestones to control the process. … Waterfall approach is a sequential process that is broken into a number of stages. The development team needs to complete one phase before proceeding to the next development phase.

Can a project have both predictive and adaptive elements?

A project cannot have both predictive and adaptive elements. A project that has high technical risk should use the predictive approach. All adaptive approaches include iterations. … A tool is a software support that helps create models or other components required in the project.

What is a adaptive approach?

An adaptive approach involves exploring alterna- tive ways to meet management objectives, predicting the outcomes of alternatives based on the current state of knowledge, implementing one or more of these alternatives, monitoring to learn about the impacts of management actions, and then using the results to update …

What are the three phases of ASD?

The ASD approach encourages teams to develop according to a three-phase process: speculate, collaborate, learn.

What type of a predictor can you use in an adaptive model?

In adaptive decisioning, this predictor selection process repeats periodically. You can use several data types in adaptive analytics, including: Numeric data – Basic numeric data such as age, income, and customer lifetime value can be used without any preprocessing.

What is the standard type of predictive approach called?

The SDLC that is the most predictive is called the waterfall model, an SDLC that assumes the various phases of a project can be completed sequentially—one phase falls into the next phase, and there is no going back as shown in Figure 10-3. This approach is almost never used any more.

Is V model predictive?

Summary. Predictive models are useful primarily because they give a lot of structure to a project. … The chapter describes some predictive software development models such as waterfall model, waterfall with feedback, sashimi model, incremental waterfall model, V-model and software development life cycle.
