Software Engineering Practice

People who create computer software practice the art or craft or discipline that is software engineering. But what is software engineering “practice”? in a generic sense, practice is a collection of concepts, principles, methods, and tools that a software engineer calls upon on a daily basis. Practice allows managers to manage software projects and software engineers to build computer programs. Practice populates a software process model with the necessary technical and management how-to’s to get the job done. Practice transforms a haphazard unfocused approach into something that is more organized, more effective, and more likely to achieve success.

Core principles
The dictionary defines the word principle as “an important underlying law or assumption required in a system of thought” throughout this book we discuss principles at many different levels of abstraction. Some focus on software engineering as a whole, others consider a specific generic framework activity (e.g., customer communication), and still others focus on software engineering actions (e.g., architectural design) or technical tasks (e.g., write a usage scenario). Regardless of their level of focus, principles help us establish a mind set for solid software engineering practice. They are important for that reason.

First principle: the reason it all exists

A software system exists for one reason: to provide value to its users. All decisions should be made with this in mind. Before specifying a system requirement, before nothing a piece of system functionality, before determining the hardware platforms or development processes, ask yourself questions such as: does this add real value to the system? If the answer is no, don’t do it. All other principles support this one.

TL Logistics Management Software is Essential to Cutting Shipping Costs

When companies grow large enough, they typically purchase their own shipping fleet and have a logistics department that manages their shipping process from a variety of vantage points. But for small to midsize companies that don’t have a shipping fleet or an in-house logistics team, carrying out and managing their shipping process means outsourcing their transportation logistics or trying to choose the right shipping options on their own. In most cases, these companies trust a third party logistics (3PL) provider to provide the best TL shipping solutions for their unique distribution needs. However, to save money and have more control over the shipping process, more and more companies are turning to truckload logistics software-also referred to as TL logistics management software. In addition to allowing small to midsize companies to become their own logistics provider, freight logistics software helps them save money with respect to the following areas of the shipping process: freight management, transportation execution and freight payment and audit.

Freight Management

Freight management amounts to managing each means freight distribution, including but not limited to: small parcel, less than truckload (LTL), full truckload (FTL), rail and sea. While large companies employ logistics professionals or construct internal freight councils, small companies typically either outsource freight management or defer to purchasing personnel or shipping or warehouse managers. By implementing TL logistics management software, companies realize more shipping options than they do from outsourcing to a 3PL provider. Because 3PL providers only use carriers that they can make the most money with, your shipping options with 3PL providers are limited to what makes the best sense for 3PL providers and not necessarily for your company.

Transportation Execution

Traditionally, transportation systems are designed for tendering outbound shipments, meaning that they aren’t designed for managing inbound and third party shipments. In addition, parcel carriers have compliance requirements that cause shippers to use a separate system for parcel processing, leading to higher freight costs. Ultimately, shippers have a difficult time keeping their freight from being tendered outside of their original pricing agreements and end up overpaying for freight transportation. To remedy this situation, TL logistics management software allows companies to enforce internal and external compliance throughout the shipping process with regard to the carrier pricing agreement.

Freight Payment and Audit

TL logistics management software allows you to combine your freight payment and pre-audit data, which gives you limitless reporting options concerning your freight spend. With the combined information uploaded to the software application’s dashboard to give you almost real time visibility of your freight spend, you can to monitor freight KPI’s on a daily basis to further control shipping costs as KPI’s change. The freight payment and auditing capabilities of truckload logistics software also allow you to receive more of your freight bills through EDI, which serves to lower your pre-audit costs.

The Software Engineer Today

Who is the programmer today?

If we ask somebody in the street “Who is the programmer?”, what does he or she answer? I believe something like “A person who sits behind the computer and creates program code” or “A person who programs actually! What a stupid question?”. Not everyone exactly understand that successful software development requires many different activities besides code construction. The approach that includes all such activities is called Software Engineering. Let’s see the important stages, that all together form software engineering.

1) Requirements.When a project starts, we have to elicit requirements for it, thoroughly handle them and create the document that is known as Software Requirements Specification. Requirement specialists start collecting requirements in the very beginning of the project and update them until the projects is ended to keep them relevant and correct mistakes that occurred during the implementation. Software Requirements Specification is a result of this process. The document contains information obtained from users, technical standards, and business rules and other.

2) Design. The other important activity is design. It includes overall planning of the project, building models and prototypes. Software Engineering standards distinguish two separate activities within the design stage: software architectural design and software detailed design. The first one is planning of the whole system, when the second one is more thorough planning of its components.

3) Construction. The next activity is actually code construction. Most people consider this thing as programming. Engineers create program code using different programming languages and software construction tools that dramatically improve the speed of the process.

4) Testing. When the code is created software engineers must test them. Testing is an activity of product quality assessment and improvement. This stage is often performed by a separate team of testers. It also can be outsourced, because external testers can check the quality impartially.

5) Maintenance. Even when all implementation activities are completed, the work on the project is not. The maintenance stage starts then. It is necessary to provide cost-effective support to software. However, even now we are talking about only post-delivery stage, which includes such things as software modifications and user trainings. However, there is another one known as pre-delivery maintenance, which includes planning of actions for post-delivery stage.

Now I think that even if you are not closely connected to programming, you know the main activities it includes, and I am sure that you realize that the programmer must do much more than only code construction.
