An existing system is previously implemented design, about which we know nothing. Designers then do reverse engineering by looking at the code and try to get the design. With design in hand, they try to conclude the specifications.
Thus, going in reverse from code to system specification. It is a process to re-structure and re-construct the existing software. It is all about re-arranging the source code, either in same programming language or from one programming language to a different one. Restructuring can have either source code-restructuring and data-restructuring or both.
Re-structuring does not impact the functionality of the software but enhance reliability and maintainability. Program components, which cause errors very frequently can be changed, or updated with re-structuring.
Forward engineering is a process of obtaining desired software from the specifications in hand which were brought down by means of reverse engineering. It assumes that there was some software engineering already done in the past. Forward engineering is same as software engineering process with only one difference — it is carried out always after reverse engineering. A component is a part of software program code, which executes an independent task in the system.
It can be a small module or sub-system itself. The login procedures used on the web can be considered as components, printing system in software can be seen as a component of the software. Components have high cohesion of functionality and lower rate of coupling, i. In OOP, the objects are designed are very specific to their concern and have fewer chances to be used in some other software.
In modular programming, the modules are coded to perform specific tasks which can be used across number of other software programs. Software components provide interfaces, which can be used to establish communication among different components. Two kinds of method can be adopted: either by keeping requirements same and adjusting components or by keeping components same and modifying requirements.
Requirement Specification - The functional and non-functional requirements are specified, which a software product must comply to, with the help of existing system, user input or both. They should help you find a happy medium between needs and your budget. Check out this managed IT services cost guide. A good investment when it comes to your IT can sometimes be hindsight. In our consumer- based culture, wanting the latest-and-greatest can hinder growth. Your technology should serve its purpose, but also be cost effective.
The total cost of ownership includes yearly maintenance of the product. There is a balance between maintaining productivity and keeping the cost at a manageable level. IT costs can be very confusing to figure out, much less compare. Breaking down your cost in categories and digging into the root of the expense can go a long way.
Understanding how your IT investment can give you a competitive advantage. Set up a meeting with your IT team today, communicate your fears and check that everything is in line with industry standards. Things change rapidly in the world of tech.
Based on that, you can make adjustments — prioritize some tasks over others, move some activities in front of others, and see where possible downtime would bring least harm. Suppose, we need to create a new software feature that requires two specialists — Developer and QA Expert — to handle full-on frontend-backend development of an asset.
Each specialist has the underlying stages to complete, including development, testing, deployment, review, etc. We take our two specialists, assign the basic tasks to them, and define how many hours each would take to complete:. All in all, we can see that the whole scope of work involving these two specialists would take approximately 30,5 hours. Always count the longest outcome possible to have back-up hours for unexpected situations. With this number of hours in hand, you can now easily calculate the cost of implementing an asset based on the rates you offer.
If you need to analyze a much more complex and multi-sided project with many features to be implemented, use the same scheme for every separate feature and activity.
Here you got an absolutely honest algorithm for calculating the costs of developing software. As you can see, we are not hiding anything and are not trying to make money where our competitors see the main source of income.
