A Review of Agile Software Effort Estimation MethodsEditor IJCATR
Software cost estimation is an essential aspect of software project management and therefore the success or failure of a software
project depends on accuracy in estimating effort, time and cost. Software cost estimation is a scientific activity that requires knowledge of a
number of relevant attributes that will determine which estimation method to use in a given situation. Over the years various studies were done
to evaluate software effort estimation methods however due to introduction of new software development methods, the reviews have not
captured new software development methods. Agile software development method is one of the recent popular methods that were not taken
into account in previous cost estimation reviews. The main aim of this paper is to review existing software effort estimation methods
exhaustively by exploring estimation methods suitable for new software development methods.

What is Computer Network?
A computer network is a set of devices connected through links. A node can be computer, printer, or any other device capable of sending or receiving the data. The links connecting the nodes are known as communication channels.
Computer Network uses distributed processing in which task is divided among several computers. Instead, a single computer handles an entire task, each separate computer handles a subset.
Following are the advantages of Distributed processing:
Security: It provides limited interaction that a user can have with the entire system. For example, a bank allows the users to access their own accounts through an ATM without allowing them to access the bank's entire database.
Faster problem solving: Multiple computers can solve the problem faster than a single machine working alone.
Security through redundancy: Multiple computers running the same program at the same time can

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

Test estimating in software development refers to the ways and approaches used to determine or
evaluate the efforts, resources and timelines required for testing in software development projects.
What is software test estimation?
Software Development test estimation is a managerial task involving assessing and approximating
the necessary time, resources, and costs for executing tests in a specific environment. Additionally, it
serves as a projection, preventing time constraints and avoiding exceeding budgets.
Why test estimation?
Key reasons for conducting test estimation
Facilitating Project Planning:
Accurate estimations helps project managers to maintain a well-organized project timeline. By
having a clear understanding of the time required for testing activities, realistic schedules can be
developed, ensuring effective coordination with development and other project tasks.
Efficient Resource Allocation:
With reliable test estimations, resource allocations, such as the testing tools in software testing,
number of testers and required testing environments, can be handled with precision. This ensures
that resources are neither overallocated nor underutilised.
Effective Budgeting and Cost Control:
The success of a project depends on the effective management of budgets. Effective management
requires the evaluation of many expenses like infrastructure costs, personnel costs, and tooling
costs. Having a good understanding of the expected expenses, organisations can make better
budget decisions.
Proactive Risk Management:
Estimations provide visibility into potential risks associated with testing, allowing for proactive
implementation of risk mitigation strategies. This ensures that areas requiring additional attention or
resources are addressed promptly.
Aligning Stakeholder Expectations:
Estimation sets true expectations with project stakeholders, fostering clear communication with
clients, managers, and development teams.
Optimizing Projects:
Accurate estimation facilitates better planning and optimization of testing activities. It identifies
opportunities for process improvements, resource optimization, and automation, leading to
increased productivity in the testing process.
What To Estimate?
Estimation techniques are undertaken to assess various factors of software development. These
techniques are used in knowing the time, resources, efforts, and expenses associated with different
components of a project.
1. To begin with, estimation techniques allow for the evaluation of the effort needed for diverse
activities such as analysis, design, coding, testing, documentation, and project management.
2. These techniques prove valuable in determining the time required to accomplish the entire
project or specific milestones, taking into account dependencies and constraints.
3. Estimation techniques are helpful in the assessment of necessary resources including tools, team
members, skillsets and infrastructure.
4. Moreover, these techniques can be applied in estimating the complex features, potential risks,
and uncertainties and also measure the effort needed for documentation and project tasks.
Test Estimation Techniques
Common and Widely Utilized Test Estimation Techniques
1. Work Breakdown Structure:
This involves breaking down a large task into smaller, more manageable groups for easier execution.
2. 3-Point Software Estimation Test:
Tasks are dissected into smaller components, and each is estimated using three points – Best case,
Most likely, and Worst case scenarios.
3. Wideband Delphi Method:
This technique brings together a panel of experts to collectively determine the most probable
outcome, reaching a common consensus.
4. Functional Point Analysis:
Breaking down extensive tasks into smaller components, with each small task estimated based on
factors like size, cost, and project duration.
5. Agile Techniques:
Agile estimation techniques utilize current data and past experience for estimation, continuously
integrating new information into the project to enhance the estimation process.
6. Distribution in Percentage:
Each stage is evaluated in terms of percentages to determine the effort allocation for each phase of
the testing cycle.
Insights about Agile Estimation – Benefits and Successful
Story Points
Agile estimation involves gauging the effort needed to complete a prioritized task within the product
backlog. This estimation is focused on determining the time required for task completion,
enhancing the accuracy of sprint planning.
Teams engage in Agile estimation for several reasons. Overestimation and underestimation are
common challenges in Agile software development companies, resulting in unpredictable
development and launch times. Early consideration of Agile estimation is essential for achieving
accurate user story estimations. This practice ensures that the team remains focused on deliverables
and avoids unnecessary deviations.
Here are some benefits of Agile Estimation techniques
Informed Decision-Making
Accurate Agile estimation empowers the development team to conduct effective backlog grooming
sessions, leading to precise sprint planning. Informed decisions based on reliable estimates
contribute to improved user story delivery times.
Enhanced Coordination
Agile estimation facilitates better coordination within the team. For instance, when user story A is
estimated at two weeks and user story B at four weeks, interdependencies between the two stories
necessitate careful prioritization, ensuring simultaneous completion and fostering improved
teamwork.
Effective Risk Management
Agile project estimation is a key component in mitigating risks associated with budget and timeline
overruns. Accurate estimates, including story points, enable teams to adhere to budgets, timelines,
and project scope, reducing the risk of delays and ensuring on-time, quality delivery.
Agile estimation, when executed thoughtfully, not only addresses challenges related to
overestimation and underestimation but also contributes to the overall success of software projects.
It provides teams with the necessary tools to make informed decisions, enhance coordination, and
effectively manage risks throughout the development process.
Streamlining Agile with Effective Story Point Adoption
Successfully employing story point estimation in Agile involves a systematic process leveraging
historical data for accurate project assessment.
The sequential steps for Implementing this estimation technique are as follows:
1. User Story Identification:
Begin by identifying user stories that encapsulate the project’s features. The Product Owner or
business analyst plays a crucial role in discussing the story requirements and clarifying any
uncertainties surrounding the story’s content.
2. Requirement Discussion:
Engage in comprehensive discussions about the user story requirements. The Product Owner or
business analyst takes on the responsibility of responding to queries and providing a clear
understanding of the story’s essence.
3. Estimation Matrix Creation:
Develop an estimation matrix, a numeric scale used to assess the chosen pieces of work. This scale
could be based on the Fibonacci sequence (e.g., 5, 8, 13, 21, 34) or a straightforward linear scale
(e.g., 3, 4, 5, 6, 7). The matrix serves as a reference point for evaluating the complexity of each task.
4. Agile Estimation Technique Selection:
Choose an Agile estimation technique that aligns with the team’s preferences and the project’s
specific requirements. Whether using Planning Poker, T-Shirt Sizing, or other methods, select the
most suitable approach for your team.
5. Sprint Planning:
Implement sprint planning based on the estimates derived from the chosen Agile estimation
technique. This phase involves allocating tasks to specific sprints and creating a roadmap for project
execution.
6. Internal Consistency Validation:
Throughout the process, validate that the estimates maintain internal consistency and align with the
respective user stories. This ensures that the estimation framework remains reliable and accurately
reflects the complexities of the tasks.
By following these steps, teams can effectively leverage story point estimation in Agile, utilizing
historical data to enhance the precision of project estimates. This method not only streamlines the
planning process but also promotes better alignment between estimations and the actual execution
of user stories.
Test estimation best practices
Test estimation stands as a pivotal element within the software development cycle, playing a crucial
role in effective planning, resource allocation, and overall project management. To ensure precision
and reliability in the estimation process, consider the following best practices:
1. Thorough Understanding of Requirements:
Before initiating the estimation process, it is imperative to possess a comprehensive understanding
of the project requirements. Any ambiguities or incomplete information may lead to inaccuracies in
the estimates.
2. Breakdown of Tasks:
Rather than providing a singular estimate for the entire project, break down the testing effort into
smaller, more manageable tasks. This approach enhances precision in estimation and mitigates the
risk of overlooking crucial aspects.
3. Historical Data:
Leverage historical data to expedite and enhance the estimation process. Previous projects with
similar scopes and complexities can serve as valuable reference points, offering insights into the
testing effort required.
4. Working with Right Experts:
Seek input from team members who have experience with similar story estimations. Involving
experienced testers, test leads, and other stakeholders can significantly improve the accuracy of
estimates.
5. Employ Estimation Techniques:
Select and apply the most appropriate estimation technique based on the unique characteristics of
the project. Some examples are selenium testing and agile methodology in testing. Tailoring the
approach to the project’s specific requirements enhances the accuracy of estimates.
6. Consider Risk Factors:
Identify potential risks that may impact testing efforts early in the process. Allocate additional time
to accommodate unforeseen issues that could arise during testing.
7. Account for Environment and Infrastructure:
Ensure that the estimation accounts for the time required to set up and maintain the necessary test
environments, tools, and infrastructure.
8. Review and Validate:
Seek a fresh perspective by having someone else review the estimations. This external input can
contribute to more accurate estimations by identifying any oversights.
9. Update Estimations:
As the project progresses and more information becomes available, periodically reassess and
update the estimates. Document the reasons for any adjustments made to the original estimation.
10. Track and Learn:
Maintain a record of the actual time and effort expended on testing activities, and compare this
data with the estimated values. Analyze any discrepancies to derive insights that can be applied to
enhance future estimations.
Caution
Keep in mind that estimation is not an exact science, and unexpected situations can influence the
actual effort needed. It’s essential to regularly review and modify the estimates as the project
advances to ensure a successful testing phase.
Conclusion
Test estimation techniques aren’t limited to software testing; they offer value throughout the entire
software development life cycle. By combining the mentioned methods, a more accurate and
precise estimation can be achieved. Ensuring accurate estimates for any project is crucial for
optimizing the use of resources, time, and skills to their fullest potential.
