Why Rapid Development Became Critical

1 pts

volume_mute

Rapid development and delivery is now often the most critical requirement for software systems. Why?

Because developers prefer writing code without detailed specifications

Because businesses operate in a rapidly changing environment and must respond to new opportunities, markets, and competitive pressures quickly

Because agile tools have become cheaper and easier to use

Because hardware has become so powerful that software can always be rewritten quickly

Explanation

Why Stable Requirements Are Hard to Achieve

1 pts

volume_mute

Why is it often practically impossible to derive a complete set of stable software requirements for business systems?

Because formal requirements techniques are too expensive for most businesses

Because customers deliberately withhold requirements to reduce costs

Because requirements inevitably change — customers cannot predict how a system will affect working practices, how it will interact with other systems, and what user operations should be automated until they gain experience with it

Because development teams lack the skills to capture requirements accurately

Principle

Customer involvement

People not process

Embrace change

Maintain simplicity

Description

Customers should be closely involved to provide and prioritise new system requirements and to evaluate iterations

The skills of the development team should be recognised and exploited — team members develop their own ways of working without prescriptive processes

Expect the system requirements to change and design the system to accommodate these changes

Focus on simplicity in both the software being developed and the development process — actively work to eliminate complexity

Incremental Delivery Principle

1 pts

Complete the sentence about the incremental delivery principle in agile methods.

The software is developed in increments with the (1) specifying the requirements to be included in each increment. The system is developed as a series of (2), with each including new system functionality.

What Agile Methods Are Best Suited For

1 pts

volume_mute

Agile methods have been very successful for certain types of system development. Which two types are identified? Select both.

Product development where a software company is developing a small or medium-sized product for sale

Very large distributed systems where multiple teams work in different time zones

Custom system development within an organisation where the customer is committed to being involved and there are not a lot of external rules and regulations

Safety-critical embedded systems with complex timing requirements

Agile vs Plan-Driven — Key Distinction

1 pts

volume_mute

What is the key distinction between how agile methods and plan-driven methods minimise documentation?

Agile methods use automated tools to generate all documentation; plan-driven methods require manual documentation

Plan-driven methods minimise documentation; agile methods maximise it

Agile methods minimise documentation by using informal communications rather than formal meetings with written documents; plan-driven methods use formal documents to communicate between stages

Agile methods produce no documentation at all; plan-driven methods produce complete documentation

Problems with Agile Principles in Practice

1 pts

volume_mute

Several agile principles can be difficult to realise in practice. Which of the following are identified difficulties? Select all that apply.

Prioritising changes can be extremely difficult when there are many stakeholders who give different priorities to different changes

Maintaining simplicity requires extra work and delivery pressure may prevent simplification

Individual team members may not have suitable personalities for the intense involvement typical of agile methods

Customer involvement depends on having a customer who is willing and able to spend time with the development team and can represent all stakeholders — this is often not possible

Agile methods always produce lower-quality code than plan-driven approaches

Agile Methods and Maintenance

1 pts

volume_mute

Two questions should be considered when using agile methods for software maintenance. Which of the following correctly states both?

Are systems developed using an agile approach maintainable given the emphasis on minimising formal documentation? And can agile methods be used effectively for evolving a system in response to customer change requests?

Can agile methods be used for safety-critical systems? And can agile methods be scaled to teams of thousands of developers?

Do agile methods reduce staff costs? And do agile methods eliminate the need for project management?

Can agile methods reduce testing costs? And can agile methods eliminate the need for documentation entirely?
