Requirements Analysis and Design Definition (KA) - Define Design Options (Task) - Study

Requirements Architecture

The full set of requirements and their relationships is important for defining design options that can address the holistic set of requirements

Define Design Option Purpose 1

The purpose for the Define Design Option task is to: o Define the solution approach o Identify opportunities to improve the business o Allocate requirements across the solution components o Represent design options that achieve the desired future

When Designing Solution May be One or More Design Options Identified

When designing a solution, there may be one or more design options identified

Change Strategy - Inputs

o Describes the approach that will be followed to transition to the future state o This may have some impact on design decisions in terms of what is feasible or possible

Define Design Option Identifies, Explores and Describes Different Possible Ways to Meet the Need

o Identifies o Explores o Describes different possible ways of meeting the need

Requirements (validated, prioritized) - Inputs

o Only validated requirements are considered in design options o Knowing the requirement priorities aids in the suggestion of reasonable design options o Requirements with the highest priorities might deserve more weight in choosing solution components to best meet them as compared to lower priority requirements

Design Options - Outputs

- Describes various ways to satisfy one or more needs in a context - Designs include: o Solution approach, o Potential improvement opportunities provided by the option and o The components that define the option

Inputs

1. Change Strategy 2. Requirements (validated, prioritized) 3. Requirements Architecture

Define Design Options Elements

1. Define Solution Approaches 2. Identify Improvement Opportunities 3. Requirements Allocation 4. Describe Design Options

Design Options Exist at Lower Level Than Change Strategy and Are Tactical Rather than Strategic

Design options exist at a lower level than the change strategy and are tactical rather than strategic

As Solution Developed, Tactical Trade-offs May Need to be Made Among Design Alternatives

As a solution is developed, tactical trade-offs may need to be made among design alternatives

As Initiatives Progress and Requirements Evolve, Design Options Evolve

As initiatives progress and requirements evolve, design options evolve as well

BA's Must Assess Effect Trade-offs Will Have on Delivery of Value

Business Analysts must assess the effect these trade-offs will have on the delivery of the value to stakeholders

Each Option Represents Way to Satisfy Requirements

Each design option represents a way to satisfy a set of requirements
