Effect of Implementation Planning and Role of Affinity Analysis in Reengineering Effort:
Implementation planning plays a crucial role in the success of software reengineering efforts (Pressman, 2014). Affinity analysis, a technique used in implementation planning, helps identify relationships between various elements and activities, facilitating a more organized and efficient reengineering process.
For example, during the reengineering of a legacy system, affinity analysis can be applied to understand the dependencies between different modules or components (Sommerville, 2011). By grouping related tasks or components together, the implementation plan can prioritize areas that are tightly interconnected, reducing the risk of errors and ensuring a smoother transition.
The results of affinity analysis
include a visual representation of relationships and dependencies, helping project managers allocate resources effectively and schedule tasks in a logical order. This analysis aids in identifying critical paths, dependencies, and
potential bottlenecks, contributing to a more efficient and successful reengineering effort.
Importance of Cost and Schedule Estimates Before Detailed Requirements/Design Analysis:
Cost and schedule estimates are essential early in the software development life cycle because they provide a basis for decision-making, resource allocation, and project planning (Sommerville, 2011). Detailed requirements and design analysis often depend on accurate cost and schedule estimates to establish project feasibility and define the project scope.
For instance, in a software development project, if a preliminary cost estimate reveals that the project is financially viable, detailed requirements analysis can proceed to define the specific functionalities and features. Similarly, schedule estimates help in planning milestones and deadlines, guiding the subsequent design phase.
These estimates are done early in the process because they provide critical information
for stakeholders and project managers to make informed decisions about whether to proceed with the project. Without these estimates, it's challenging to secure necessary resources, set realistic expectations, and establish a feasible project timeline.
Postponing Cost and Schedule Estimates:
While early estimates are crucial, there might be cases where detailed estimates can be
postponed to a later stage of software development. This could be applicable in agile methodologies where iterative development and continuous feedback allow for flexibility in adapting to changing requirements.
For example, in an agile environment, the focus is on delivering working software in short iterations. Detailed estimates may be revisited and refined at the start of each iteration based on the evolving understanding of requirements and feedback from previous iterations. This adaptive approach acknowledges that detailed estimates can evolve as the project progresses.
In conclusion, implementation planning, utilizing techniques such as affinity analysis, is crucial for the success of reengineering efforts (Pressman, 2014). Early cost and schedule estimates are vital for informed decision-making and project planning, but in agile methodologies, these estimates can be revisited and refined during the iterative development process.
