Most effort spent management the project schedule occurs during

The project management triangle called also the triple constraint , iron triangle and project triangle is a model of the constraints of project management. While its origins are unclear, it has been used since at least the s. For example, a project can be completed faster by increasing budget or cutting scope. Similarly, increasing scope may require equivalent increases in budget and schedule. Cutting budget without adjusting schedule or scope will lead to lower quality. Choose two.

The Eisenhower Matrix

Email: solutions altexsoft. When you buy a pear, you can instantly evaluate its quality: the size and shape, ripeness, the absence of visible bruising. But only as you take the first bite, will you be able to see if the pear is really that good. Even an extremely good-looking pear might taste sour or have a worm in it. The same applies to almost any product, be it a physical object or a piece of software.

A website you find on the Internet might seem fine at first, but as you scroll down, go to another page, or try to send a contact request, it can start showing some design flaws and errors. This makes quality control so important in every field, where an end-user product is created. That is why we at AltexSoft put a premium on the quality of software we build for our clients. In this paper, we will share our insights on the quality assurance and testing process, our best practices and preferred strategies.

While to err is human, sometimes the cost of a mistake might be just too high. History knows many examples of situations when software flaws have caused billions of dollars in waste or even lead to casualties: from Starbucks coffee shops being forced to give away free drinks because of a register malfunction, to the F military aircraft being unable to detect the targets correctly because of a radar failure. Watch the video to learn what events triggered the development of software testing and how it has evolved through the years.

In order to make sure the released software is safe and functions as expected, the concept of software quality was introduced. These so-called explicit and implicit expectations correspond to the two basic levels of software quality :. The structural quality of the software is usually hard to manage: It relies mostly on the expertise of the engineering team and can be assured through code review, analysis and refactoring.

At the same time, functional aspect can be assured through a set of dedicated quality management activities , which includes quality assurance, quality control, and testing. Often used interchangeably, the three terms refer to slightly different aspects of software quality management. Despite a common goal of delivering a product of the best possible quality, both structurally and functionally, they use different approaches to this task.

As follows from the definition, QA focuses more on organizational aspects of quality management, monitoring the consistency of the production process. This activity is applied to the finished product and performed before the product release. In terms of manufacturing industry, it is similar to pulling a random item from an assembly line to see if it complies with the technical specs.

Testing is the basic activity aimed at detecting and solving technical issues in the software source code and assessing the overall product usability, performance, security, and compatibility. It has a very narrow focus and is performed by the test engineers in parallel with the development process or at the dedicated testing stage depending on the methodological approach to the software development cycle.

The concepts of quality assurance, quality control, and testing compared. Namely, it is used to make sure that every single action is performed in the right order, every detail is properly implemented and the overall processes are consistent so that nothing can cause a negative impact on the end product.

Quality control can be compared to having a senior manager walk into a production department and pick a random car for an examination and test drive. Testing activities, in this case, refer to the process of checking every joint, every mechanism separately, as well as the whole product, whether manually or automatically, conducting crash tests, performance tests, and actual or simulated test drives.

Due to its hands-on approach, software testing activities remain a subject of heated discussion. That is why we will focus primarily on this aspect of software quality management in this paper.

Formulated over the past 40 years, the seven principles of software testing represent the ground rules for the process. These are:. Testing shows presence of mistakes. Testing is aimed at detecting the defects within a piece of software. But no matter how thoroughly the product is tested, we can never be percent sure that there are no defects. We can only use testing to reduce the number of unfound issues.

Exhaustive testing is impossible. There is no way to test all combinations of data inputs, scenarios, and preconditions within an application.

For example, if a single app screen contains 10 input fields with 3 possible value options each, this means to cover all possible combinations, test engineers would need to create 59, test scenarios. In order not to spend weeks creating millions of such less possible scenarios, it is better to focus on potentially more significant ones.

Early testing. As mentioned above, the cost of an error grows exponentially throughout the stages of the SDLC. Therefore it is important to start testing the software as soon as possible so that the detected issues are resolved and do not snowball.

Defect clustering. This principle is often referred to as an application of the Pareto principle to software testing. This means that approximately 80 percent of all errors are usually found in only 20 percent of the system modules. Therefore, if a defect is found in a particular module of a software program, the chances are there might be other defects. That is why it makes sense to test that area of the product thoroughly.

Pesticide paradox. As soon as the detected errors are fixed, these test scenarios become useless. Therefore, it is important to review and update the tests regularly in order to adapt and potentially find more errors. Testing is context dependent. Depending on their purpose or industry, different applications should be tested differently.

While safety could be of primary importance for a fintech product, it is less important for a corporate website. The latter, in its turn, puts an emphasis on usability and speed. Absence-of-errors fallacy. The complete absence of errors in your product does not necessarily mean its success.

While the above-listed principles are undisputed guidelines for every software testing professional, there are more aspects to consider. Some sources note other principles in addition to the basic ones:. Waterfall Model Representing a traditional software development life cycle, the Waterfall model includes 6 consecutive phases: planning, analysis, design, implementation, testing, and maintenance. In the testing phase a product, already designed and coded, is being thoroughly tested before the release.

However, the practice shows that software errors and defects detected at this stage might be too expensive to fix, as the cost of an error tends to increase throughout the software development process. However, the damage grows exponentially throughout the further stages of the process. If such an error is detected at the design stage, you will need to rework your designs to fix it. This will require a significant amount of effort and investment.

The same is the case for errors produced in the process of implementation. If a feature has a flaw in its logic, building more functionality on top of it might cause a serious damage in the long run. Therefore, it is better to test every feature while the product is still being built. This is where iterative Agile methods prove beneficial.

Being an integral part of the software development process, Agile breaks the development process into smaller parts, iterations, and sprints.

This allows testers to work in parallel with the rest of the team throughout the process and fix the flaws and errors immediately after they occur. The main purpose of such process is to deliver new software features fast and with the best quality. Therefore, this approach is less cost-intensive: Fixing the errors early in the development process, before more problems snowball, is significantly cheaper and requires less effort.

Moreover, efficient communication within the team and active involvement of the stakeholders speeds up the process and allows for better-informed decisions.

You can find out more about roles and responsibilities in a testing team in our dedicated article. In Agile projects, QA should be embedded in the scrum teams because testing and quality is not an afterthought.

Quality should be baked in right from the start. For those who have Agile experience, DevOps gradually becomes a common practice. This new software development methodology requires a high level of coordination between various functions of the deliverable chain, namely development, QA, and operations.

A DevOps lifecycle. DevOps is often referred to as an extension of Agile that bridges the gap between development along with QA and operations.

However, unlike Agile, DevOps includes the concept of continuous development where the code, written and committed to version control, will be built, deployed, tested and installed in the production environment that is ready to be consumed by the end-user.

DevOps places a great emphasis on automation and continuous integration tools that allow for the high-velocity delivery of applications and services. The fact that testing takes place at each stage in the DevOps model changes the role of testers and the overall idea of testing. Therefore, to be able to effectively carry out testing activities, testers are now expected to have technical skills and even be code savvy.

According to the PractiTest survey , the Agile trend is an undisputed leader, while almost 90 percent of respondents work at least in some Agile projects within their organizations. That said, a third of the respondents is still applying the Waterfall model in some projects, following a steady decrease in the use of that method.

DevOps keeps growing, just slower than before. Organizing a software testing process can be quite challenging. We at AltexSoft follow the three major steps in the software testing process: planning, execution, and reporting. As any other formal process, testing activities are typically preceded by thorough preparations and planning.

The main goal of this stage is to make sure the team understands the customer objectives, the main purpose of the product, the possible risks they need to address, and the outcomes they expect to achieve.

One of the documents created at this stage, the mission or assignment of testing , serves to solve this task. Roger S. Also referred to as test approach or architecture, test strategy is another artifact of the planning stage. Depending on when exactly in the process they are used, the strategies can be classified as preventive or reactive.

In addition to that, there are several types of strategies , that can be used separately or in conjunction:. While a test strategy is a high-level document, test plan has a more hands-on approach, describing in detail what to test, how to test, when to test and who will do the test. Unlike the static strategy document, that refers to a project as a whole, test plan covers every testing phase separately and is frequently updated by the project manager throughout the process.

According to the IEEE standard for software test documentation , a test plan document should contain the following information:.

Each phase of the project life cycle consists of specific project objectives, results, deliverables, processes, and milestones, and it grants project managers and organizations more control over the projects they handle. A project phase is a collection of related project management activities. Their relationship in the life cycle is often sequential, and each project phase culminates with the completion of one or more project deliverables. That said, the project management skill sets , tasks, processes, stakeholders, and involved organizations for each of the project phases would differ.

However, many others—mostly in Africa—have vaccinated only small administration launched Operation Warp Speed, a project aimed at.

The Dumbest Coup Attempt

Fahad Usmani, PMP. June 2, Risks occur in every project and as a project manager, it is your responsibility to manage them as they occur. These risks can be identified or unidentified. If these risks are identified, you will implement the contingency plan; otherwise, you will manage them through a workaround. To manage these risks, you will use the contingency reserve and management reserve. These reserves are defined during the risk management planning process. The contingency reserve and management reserve provide you with a cushion against the risks and are part of your project budget. Many professionals assume these reserves are the same since they serve the same purpose. Generally, small and medium-sized organizations do not differentiate between them and take them as a percentage of the project cost to keep things simple.

3. The Project Life Cycle (Phases)

The White House is developing a research plan that would guide and set standards for how scientists study one of the more controversial ways of counteracting climate change: solar geoengineering. The basic idea is that we might be able to deliberately tweak the climate system in ways that release more heat into space, cooling an otherwise warming planet. The move, which has not been previously reported on, marks the first federally coordinated US effort of this kind. It could set the stage for more funding and research into the feasibility, benefits, and risks of such interventions. The effort may also contribute to the perception that geoengineering is an appropriate and important area of research as global temperatures rise. Solar geoengineering encompasses a range of different approaches. These would then—in theory—reflect back enough sunlight to ease warming, mimicking the effect of massive volcanic eruptions in the past. Some research groups have also explored whether releasing certain particles could break up cirrus clouds , which trap heat against the Earth, or make low-lying marine clouds more reflective.

Accurate time estimation is a crucial skill in project management. additional effort to create three separate estimates, it allows you to set more.
