What is Software Product Line?

What are Software Product Lines?

A software product line is simply a specific demand for products related to a project. It is an effort to use it in a more efficient way. An engineering is an occupation and while benefiting from the similarities of the products, based on taking their differences into account. good planning covering all stages of production, design and delivery. carried out with a broad perspective. In this context, having less effort of different but similar products or demands in the ecosystem. to a certain systematic in order to increase the efficiency in a way that requires It should be managed by sitting down, but in this way, the operation is desired. can achieve success. Any software or mechanical engineering It can be integrated into all vehicles and all operations in the effort. In our article, we will focus on the software framework.

What are the advantages? Why Do We Use Product Line?

The Product Line is the product line that identifies different products in similar time periods. different problems because it is based on co-execution with similar approaches. reduces their complexity. That requires similar complexity. It is possible to carry out the operations in one hand and keep the efficiency high. Repetitive, a mature and well-known software product line Brings focus and increases speed. This speed is straight from the focus the same use of certain building blocks and a mature integration depends on the process.

How to Create a Software Product Line?

We can easily set up this process under 4 items. First in the main frame organization adapts. The platform of this organization adapted is installed, its scope is checked during this installation and accordingly action is taken. Afterwards, the products in the product line They think about the product-specific parts that are unique to them. determined and the installation of these parts is done. Last but not least focuses on similar parts and these points are the main parts of the product line. creates the focus. After these points are determined, with repeated use cost is reduced. Re-use saves time and cost It will increase efficiency and thus gain profit.

Total Cost can be formulated as:

Initial adaptation cost + Platform setup cost + for all products total Σ (private parts + parts to be used repeatedly)

The most important consideration when interpreting the Software Product Line One of the points is the ROI value, which means return on investment. It value is actually a very critical existence related to the software product line. is the reason. When maintaining software products in the traditional way, In general, demand is linear on the basis of time and different products. is progressing. That is, as the number of products increases, the required The effort/cost will likewise increase and progress steadily. However, in operations developed with the software product line, at the beginning of the operation there will be a certain cost need, these are to be shaped in 4 items It can be said that it is for the installation stages we have summarized. Later partner repetitive use of similarities on points on different products together with the cost requirement required after a certain point, the traditional It will give us an advantage by staying below the cost that will be required from the road. This point is called the break-even point, after this point on a cost/effort basis our software product line operation gives us measurable and considerable degree of advantage. After this stage of operation, the software Increasing the number of products in the product line gives us more advantages. can be said to provide.

 

We can easily extract the aforementioned interpretation from this graph.

Traditionally, as a result of software development, our cost is all products The cost of the product is equal to the learning index on similar products. The learning index is an index of the working team, organization, while doing similar work. equation to represent his development in the work done with the experience he has gained. It is an added term.

However, taking into account the similarities of the products with the Software Product Line repetitively within the traditional formula in the operations we have progressed. usage rate will be beneficial. This is advanced operation. means providing significant benefits to their ecosystems. software product Detailed ROI document for development is available on IEEE.

A little bit about how the applications/products are based on the similarities and differences. Let's dwell on our interpretation.

Approaches to Similarities and Differences

As a set of products we want to work on we can think. In this cluster, first of all, the similar points of the products are discussed. should be studied in detail and then the specific features of the product should be worked on. Diversity management is at the core of this operation. is the point of departure and should be well-decided and the relevant action should be taken and in this way scopes, software product architecture, components of the application and required tests must be agreed upon. Diversity in the software product line As the number of systems increases, the number of systems increases, thus keeping up with the change. potential increases. Variety can be called susceptibility to change. for example a software application has different supports on different languages it could be. How to interpret this diversity, which product, why and which We should ask questions from time to time.

Diversity to understand the interpretation of similarities and differences it is essential. Changing user needs, product change and technical Only in this way can these needs be met. Variation Similarities, differences and diversifiable points in management determines. Only certain products, not certain bands, all products living things with a certain number of features in order to determine their scope. can be classified. These are different points from the rest of the they all have features in common with the others.

Mandatory and optional to connect diversity management to a system Let's look at the points. For example, all current computers have a processor. and provides a user interface to its user. However, every the computer does not have to have a dvd reader or flash storage may not have and can be configured with. These examples can be easily reproduced. Likewise, the software will exist or There will also be components to be removed.

The Future of the Product Line

The product line is undoubtedly an important point in the software world and it is increasing day by day. increasing in popularity. Large projects or specific products It brings us a managerial discipline in the operations it manages. apparent. A very intense study on standardization and a new generation interpretation. While this is the case in development, the development of the product line that its steady increase will continue in the world and that organizations most logical about the future, which will focus more on the approach from predictions.

What is Refactoring?

Editing code pieces as necessary in the management of the software product line, Refactoring on making more efficient and purposeful interpretation We wouldn't be talking about it. First of all, answer the question of what is Refactoring? Let's call. In short, a specific purpose is adhered to by staying true to the identity of the existing code. is to be changed in order to make it more useful in line with it can be tried. As such, it also includes minor changes, eliminating new bugs that occur with different purpose integrations, or as well as changes made to make it faster. product line management, in line with new demands, apart from certain tests of the software. there may be new tests desired/needed, new changes on them may be necessary or need to be made more efficient. All of these are the purposes that make up its existence. On the benefits If we stop, it can be said that continuity and flexibility can be said in the basic scope. To eliminate errors and deficiencies on it, read the code or can eliminate functional shortcomings, thus giving us the context of continuity. will benefit. In addition, the application, for example, certain software design refactoring it by integrating it into its patterns, its existence more adequate and This new level of proficiency will make our project more efficient, as it will make it more efficient. It will make it flexible.
