Reliable Relevant Metrics to the Right Audience - Manual Testing WhitepaperIndium Software
'What cannot be measured cannot be managed” is the guiding philosophy behind testing metrics, a phenomenon that promises to deliver business efficiencies beyond just improving quality. Measurement helps with planning, tracking and managing the software project and enables organizations to objectively assess quality
To be most effective, test managers must develop and use metrics to help direct the testing effort and make informed recommendations about the software’s release readiness and associated risks. Because one important testing activity is to “measure” the quality of the software, test managers must measure the results of both the development and testing processes. Collecting, analyzing, and using metrics is complicated because many developers and testers are concerned that the metrics will be used against them. Join Rick Craig as he addresses common metrics—measures of product quality, defect removal efficiency, defect density, defect arrival rate, and testing status. Learn the guidelines for developing a test measurement program, rules of thumb for collecting data, and ways to avoid “metrics dysfunction.” Rick identifies several metrics paradigms and discusses the pros and cons of each. Delegates are urged to bring their metrics problems and issues for use as discussion points.

Measurement System Analysis is the first step of the Measure Phase of an improvement project. Before you can pass judgment on the process, you need to ensure that your measurement system is accurate, precise, capable and in control.
Testing is a process rather than a single activity. This process starts from test planning then designing test cases, preparing for execution and evaluating status till the test closure.

Measurement Systems Analysis - Variable Gage R&R Study Metrics, Applications ...Gabor Szabo, CQE
This presentation walks you through the components of variation and the various metrics used in Variable Gage R&R Study. It also talks about the different root causes associated with a failing study, and how to perform root cause analysis using statistical tools.
Software testing is an essential activity of the software development lifecycle. To ensure quality, applicability, and usefulness of a product, development teams must spend considerable time and resources testing, which makes the estimation of the software testing effort, a critical activity. This presentation presents a simple and useful method called qEstimation to estimate the size and effort of the software testing activities. The method measures the size of the test case in terms of test case points based on its checkpoints, preconditions and test data, as well as the type of testing. The testing effort is then computed using the size estimated in test case points. All calculations are embedded in a simple Excel tool, allowing estimators easily to estimate testing effort by providing test cases and their complexity.

Micro understand without Micro managing: E.g., one can identify that a
specific tester is unable to execute a test case for 2 days due to a defect unresolved by developer
Software testing is an activity which is aimed for evaluating quality of a program and also for improving it, by identifying defects and problems. Software testing strives for achieving its goal (both implicit and explicit) but it has certain limitations, still testing can be done more effectively if certain established principles are to be followed. In spite of having limitations, software testing continues to dominate other verification techniques like static analysis, model checking and proofs. So it is indispensable to understand the goals, principles and limitations of software testing so that the effectiveness of software testing could be maximized.
Software testing for project report .pdfKamal Acharya
Methods of Software Testing There are two basic methods of performing software testing: 1. Manual testing 2. Automated testing Manual Software Testing As the name would imply, manual software testing is the process of an individual or individuals manually testing software. This can take the form of navigating user interfaces, submitting information, or even trying to hack the software or underlying database. As one might presume, manual software testing is labor-intensive and slow.
Software testing is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. I hope this ppt will help u to learn about software testing.

In many web or cloud applications, performance testing is critical part of application testing since it affects
business revenue, credibility, and customer satisfaction. Conventional software development models are known
to pushing the performance testing to the very end of project, with the expectations that, only minor tweaks
and tune up are required to meet the performance requirements from the business, however any major
performance bottlenecks found during this phase were major factors for delay in Go to Market. With more and
more companies are adapting the agile software development process which believes in performance testing
should never be an afterthought but it should tightly integrate from initial planning to production analysis of
software development lifecycle. This white paper explains how any company can integrate performance testing
into agile process, and key barriers for agile performance testing when team decides to adopt agile performance
testing.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

Why React Native as a Strategic Advantage for Startup Innovation.pdfayushiqss
Do you know that React Native is being increasingly adopted by startups as well as big companies in the mobile app development industry? Big names like Facebook, Instagram, and Pinterest have already integrated this robust open-source framework.
In fact, according to a report by Statista, the number of React Native developers has been steadily increasing over the years, reaching an estimated 1.9 million by the end of 2024. This means that the demand for this framework in the job market has been growing making it a valuable skill.
But what makes React Native so popular for mobile application development? It offers excellent cross-platform capabilities among other benefits. This way, with React Native, developers can write code once and run it on both iOS and Android devices thus saving time and resources leading to shorter development cycles hence faster time-to-market for your app.
Let’s take the example of a startup, which wanted to release their app on both iOS and Android at once. Through the use of React Native they managed to create an app and bring it into the market within a very short period. This helped them gain an advantage over their competitors because they had access to a large user base who were able to generate revenue quickly for them.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

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?
We describe the deployment and use of Globus Compute for remote computation. This content is aimed at researchers who wish to compute on remote resources using a unified programming interface, as well as system administrators who will deploy and operate Globus Compute services on their research computing infrastructure.

2. Background
Introduction
Well defined test performance indicators support decision making by management and also provide a methodi-
cal approach to assess the efficiency and effectiveness of current test processes. Assessment of software quality
and process efficiency gets skewed, resulting in wrong decisions, when proper test performance indicators and
measurements are not defined and agreed.
Although there are several software test performance indicators defined by practitioners, researchers and
professionals, they may be either used in isolation or worse, wrong indicators may be used. This white paper
describes the metrics used by Idexcel, and how they help our clients.
Test Performance Indicators (TPIs) are high level metrics of effectiveness or efficiencies used to guide and
control progressive test development, test process and product quality. Idexcel has adopted the Test Maturity
Model (TMMi) process model for all its testing projects, and TPI’s are defined in line with the best practices
recommended by TMMi. While developing these TPI’s, Idexcel has established procedures for data collection,
owners, storage, analysis and reporting of TPI’s. The key project stakeholders periodically analyze the reported
data and take necessary action.

Test Performance Indicators
3. Test Performance Indicators
Used by Idexcel
In line with industry practices, Idexcel has broadly classi-
fied TPI’s into two broad categories: “Test Process
Indicators”, and “Product Quality Indicators”.
Test Process Indicators (TPIs)
One of the objectives of Idexcel’s Test Policy is to
provide a cost effective and efficient software testing
process to its customers. To meet this objective, we
continuously measure the effectiveness and efficiency
of software testing. This helps in assessing the quality
and effectiveness of the process and productivity of the
personnel involved in testing activities and this in turn
helps to improve the software testing procedures,
methods, tools and tasks. Gathering these TPI’s help
Idexcel to analyze the data and learn from historical
data, resulting in improved software testing maturity.
Product Quality Indicators
The TPI’s provide insight into test state and testing
status of a software product to engineers and project
stakeholders and are generated by test execution, code
fixes and deferment. Using these metrics, we measure
the product test state and indicative the level of quality.
Based on experience gained by working with several
customers, we have redefined product quality metrics
into two parts, ‘Product Quality TPI’s and ‘Customer
Oriented Indicators’.

Effort Variance
This is a process efficiency indicator which helps in
understanding any extra effort injected into a testing
project to complete the activities which were planned at
the beginning of the project. This indicator combined
with the phase wise effort indicator gives insights to
address the problematic phases that must be improved
in terms of efficiency and effectiveness. On the contrary,
if investigations reveal that the benchmarking used for
initial efforts estimation needs tweaking based on
changed circumstances, management can take the
necessary action to revise the benchmark.
Negative results are a good sign for management, as
they can use these negative results to revise the organi-
zation wide bench mark for effort estimation of similar
projects.
Defects Slippage
This is one of the most important ‘Process Effectiveness’
indicators that helps in identifying the effectiveness of
the testing process adopted by an organization. Defects
Slippage is directly related to the company’s reputation,
warranty costs, future business, contract requirement
and customer satisfaction. Idexcel regularly monitors
this indicator by project and analyzes the data to identi-
fy and plug gaps in the existing testing process.
Defect Removal Efficiency
This is a ‘Process Efficiency’ indicator that indicates the
defects removed per time unit (hours/-
day/weeks/phase)
Idexcel has derived this indicator directly from the orga-
nization’s debug policy, and this indicator denotes the
efficiency of defect removal methods and is also an

Used by Idexcel
Phase-Wise Testing Effort
This Process efficiency indicator helps in identifying the
intensive effort areas during prevention, verification
and validation attributes in the project. Prevention
activities include planning, training and validation &
verification activities and include time spent on tasks
such as test case walkthroughs, reviews, environment
set up, testing, test requirement, re-test etc. Examples
of phase-wise effort in testing is shown in the chart
below.
Cost Variance
This is a process efficiency indicator which helps in
understanding actual cost versus planned and budgeted
expenditure. Whenever testing cost overshoots the
budgeted cost, management can analyze and gain
in-depth understanding of the lessons learned during
the given project, and this understanding can be used to
l the testing costs of future projects. However, due to
changes in some internal or external factors, the bench-
mark used for creating budgets may become outdated,
and hence overshoot.

indirect measurement of the quality of a product. We
calculate these indicators at every stage of the software
development lifecycle and maintain the DRE for differ-
ent stages such as unit, integration, System, UAT, opera-
tional readiness, documentation.
Defect Rejection Ratio
Some of the assumptions made during the process
controlled software development for testing activities
are:
1. Testers understand the application and minor details
of the requirements
2. All decisions related to requirements are well com-
municated to the testers, and revised documents are
shared with them
3. Testing happens in a controlled test environment
4. Configuration management is in place and testers are
getting the intended build for testing
5. Testers are well trained in application process and
business logic.
A defect initially raised by a tester could be later reject-
ed if any one of the above assumption goes wrong. The
main objective of this ‘Process Effectiveness’ indicator is
to ensure that testers correctly understand the require-
ments and get involved in all the phases of the software
development lifecycle. Too many rejected defects result
in inefficiency, and indicate the lapse in process effec-
tiveness.
Test Execution Productivity Trend
This Process efficiency indicator helps find the produc-
Test Performance Indicators
tivity of the test team. Productivity may be defined as
test cases executed by a team per unit time (hours/-
days/weeks/phase/release). This indicator helps in
identifying the problematic areas impacting a team’s
productivity and helps take remedial action.

The purpose of the Test Coverage indicator is to assess
whether sufficient testing has been performed, and
identify areas that may require additional testing. This
metric measures the number of test cases tested
successfully against total number of test cases planned
for each product component at major milestones of the
software development life cycle. This indicator tells us,
what is missing much better than what is done well.
Scope Volatility
After the requirements and deliverables are signed off,
requirement volatility becomes a major factor, especial-
ly on testing tasks in a program/project. Requirement
volatility can be categorized into the following types:
addition to existing requirements, deletion from existing
requirements, change in scope to an existing require-
ment and shift in design. Under the definition of scope

volatility, we can also include specific issues related to
testing such as re-opening fixed defects, multiple builds
handed over to a testing team and change in configura-
tions.
These indicators not only measure the test team’s
efficiency against changes in project dynamics, but also
demonstrate process stability and improvements
required in the existing process. The following diagram
shows the scope volatility caused by different reasons.
Origin of Defects
This is a ‘Test Effectiveness’ indicator showing the
software development phase or activity in which the
defect occurred. This indicator helps in analyzing:
1. Major problem areas in project/program or company-
wide projects/programs,
2. Patterns in defects
3. Scope to build a baseline that characterize errors,
faults or failures

4. Pattern associated with defects that will support
prediction
The classification of software development phases
contributing to defects is showing in the example below.

Defect Priority
This indicator provides insight into the quality of the prod-
uct under test. High priority defects indicate a low product
quality. This information helps project stake holders to
make release decisions based on the number of defects
and their priority levels. Defect priorities may be classified
as “Critical”, “Major”, “Minor”, “Medium”, and “Low” and
must be consistently applied across different projects in an
organization.
Defect Distribution across components
This indicator gives information about the way defects are
distributed across the various components of the system.
We also assign priorities for different components or
sub-systems, helping the project stakeholders to assess
risks and address issues in components or subsystems that
are critical to the product, ahead of others.

Time to Fix Defects
This indicator gives insight into the effort required to fix
defects by priority. This is the time elapsed between
reporting a defect and closing the defect after retesting.
Idexcel represents this with two sets of charts: a bar chart
with current values with each priority and historical trend
over all priorities. This is a key indicator for maintainability
of the product and serves as an input to project mainte-
nance cost and patch schedules.
Status Indicators
These indicators give status of test execution per unit time.
These indicators give management the overall status of
test activity and product quality. This indicator includes
“number of test cases”, “Number of test cases executed”,
“Number of Test cases passed”, “and “Number of Test
cases failed”.
Defect Arrival Rate
This indicator gives a high level status of active defects for
a project along with daily defect open rates, showing the
trend in the quality of the product. Ideally, the defects
reported should show a declining trend over time especial-
ly when nearing the UAT/production release. Management
and project stakeholders can take product release
decisions based on this indicator.
Cumulative Defects by Status
This indicator helps to evaluate the number of defects by
status in a particular release. This indicator can ensure that
all the known defects have been corrected and action
plans are in place for open defects. This indicator
combined with Defect Removal Rate indicator helps in
making release decisions better.

Examples of decision criteria we set for a particular
program are:
1. Zero open critical defects
2. Less than 5% open defects with stake holders’ approval
and workaround
3. Open minor defects are less than the agreed numbers
4. Defect arrival rate shows a declining trend towards zero
over the last few measurement periods.
Metrics or performance indicators discussed so far
address the needs of testing process product quality. How-
ever, we believe that successful customer experience
management requires collection and analysis of different
types of customer related metrics. Customer related
metrics helps us to manage customer relationships and
identify improvement opportunities for improving
customer satisfaction.
Some of the customer related metrics are discussed
below.
Customer Problem Metrics
These metrics measure the problems that customers
encountered while using the product. We consider all

problems encountered by our customers while using the
software product, as problems with the software and not
just the valid defects. Problems that are not valid defects
could be usability problems, ambiguous documentation
etc. By carefully analyzing these metrics, we can:
• Improve the software development life cycle processes
and reduce product defects
• Reduce the non-defect-oriented problems by improving
all aspects of a products (such as usability, documenta-
tion), customer education, and support.
Financial Performance Index
These metrics will help us in achieving a lower targeted
level of budget spend on testing, and help us to turn
testing into a more efficient process.

Conclusion
Continuous improvement is the key to success for any process. Well defined test performance indicators
provide a methodical approach to assess the efficiency and effectiveness of the current test processes and
significantly improve the testing process in terms of coverage, time and quality.
