What are different scrum controls?

It happens in some of the cases that the whole scrum process comes on the verge of the collapsing! In such cases it is required that the management controls stay in order, undisturbed and firm all the times. 

There are many scrum controls; however the risk assessment continues to be the most valuable one with its impacts as well.

What are different Scrum Controls?

The below mentioned are the effective scrum controls:

1. Issues: 

Issues can be thought of as the obstacles that do not pose any major risk, defect or bug but cannot be considered to be a positive aspect for the software project.

2. Risk assessment: 

This is the most influential scrum control also as it influences the other scrum controls quite much. The success of the project depends largely up on this scrum control as well its impacts.

3. Packets: 

These are product elements pending for the modification in order to facilitate the implementation of the product backlog items in to the working software that is to be released at the end of the sprint.

4. Backlog: 

This backlog consists of all the details of the bugs, defects and the requests of the customers that could not be implemented in the current release and have to be incorporated in to the next release. In addition to all these, the backlogs also consist of the technology and functionality upgrades.

5. Solutions: 

These are the scrum controls occurring between the risks, problems and changes.

6. Release and Enhancement: 

After the risk assessment, this is the second most valuable scrum control for the entire development cycle. This scrum control at any point of time represents a viable release based up on the requirement variables.

How does these scrum controls help?

- Most of the above mentioned scrum controls are employed for the management of the product backlogs and the sprint backlogs. 

- These scrum controls are used for the following purposes:

1. Managing issues
2. Obtaining better solutions

- Even these controls are reviewed from time to time and modified or reconciled if and whenever required during the sprint planning meetings. 

- These scrum controls help control chaos that occurs during the development process. 

- All the above mentioned scrum controls play a great role in the following stages of the scrum:

1. Defined processes
2. Project cost
3. Final product
4. Responsiveness to the environment
5. Completion date
6. Knowledge transfer
7. Team flexibility creativity
8. Probability of success

Scrum, we can say is an enhanced version of the iterative and incremental object oriented development cycle. 

The software releases in a scrum are planned according to the below mentioned variables:

1. Time pressure: Time frame required to make most of the competitive advantage.
2. Quality
3. Resource: It includes staff availability and funds.
4. Vision (system vision)
5. Competition: What is required to gain the competitive edge?
6. Customer requirements: How the current system can be enhanced?

All the above mentioned can be modified according to the development plan during the project. But any processes carried out further should take these changed variables in to account. A system that requires a complicate and complex development process require appropriate control and maximum and efficient control.

What is the difference between re-test and regression testing?

Software re- testing and regression testing are the two concepts which are often misunderstood by the people. These two software testing concepts will be focused up on in this article. These two terms are often mistaken as the same thing but, it is not so. There is a considerable difference between the two.

Concepts of Re-testing

- As we all know, the field of software testing is continually improving, it becomes necessary to modify and re- test the existing software components to make them compatible with the new advanced technology.

- It becomes necessary to retest those old software components to check how much they have been affected by the changes and what all improvements and modifications are needed to make them at par with the new technology.

- So we see that testing a software component for another time is called re- testing.

Concepts of Regression Testing

- Testing these software components again and again for the sake of improvement and modification is what is called regression testing.

- We can formally define the regression testing as the software testing methodology that seeks to dig out new errors and bugs after the all other types of software testing have been carried out on the system and the required changes have been made to root out those bugs and flaws.

- It is mostly emphasized on testing the patches, enhancements and of course configuration changes.

- Regression testing is aimed at determining whether or not the modifications or enhancements have introduced new bugs and errors.

- Another purpose of carrying out regression testing is to ensure that the any changes in one component do not affect the functioning of the other components of the software system or application.

- Executing the already executed tests and observing the behavior as well as the outcome of the program, is the most common approach to the regression testing.

- Regression testing also sees to it that the faults that were fixed previously do not occur again.

- Regression testing like any other testing also consumes so much of time and effort.

- Therefore, in order to cut down the testing time and improve the efficiency of regression testing, the tester can select only few of the required test cases and execute them once again.

- Regression testing is the most costly software testing methodology that is ever employed in a software testing life cycle.

- An aggressive research has been carried out on the regression testing and many issues have been discovered with the regression testing.

Process may be either of deployment or development, because of both of them changes are made in the software system like adaptation to changes, enhancement of functionality and bug fixing etc.

Retesting and regression testing are seen as one of the most expensive software testing processes.

- These two testing processes can take up to 80 percent of the total budget of the software testing and accounts for 50 percent of the total project budget.

- For normal development processes, it is ok if the regression testing is carried after the changes have been made to the software system for every regular builds or before the final release of the software.

- But, for the agile development processes, the regression testing should be carried out after every time the software program is compiled and saved.

- For other types of development, the regression testing can be carried out before the release of the patches like security patches and so on.

- In whatever way or on whatever time the regression testing might be performed, its aim is always the same i.e., giving the assurance that the changes made to the software act as expected and do not affect the other components of the program.
