How can the answer be improved? EASY-TO-USE SPREADSHEET SOFTWARE FOR PIPE SIZING AND VESSEL ENGINEERING. Insulation thickness as well as the temperature change in the. Software Engineering Stack Exchange is a question and answer. How to choose work item size. I'd recommend using either fibnacci or t-shirt sizing for size.

1.Population:By taking a static count of Object Oriented Entities,exa:Classes and Operations. 2.Volume:The Population measured but are collected dynamically at given instance of time.(the poulation may be changed after multiple uses of diferent entities so its called Dynamically) 3.Length:A chain of interconnected design elements such as:inheritance tree with its length. 4.Functionality:indirect indication of the value delivered by aplication.(software size depends on user is required functionality of application or a Software.

A Software Engineer does many things (I  know as I was one for 14 years and before that worked with them as  a Hardware Technician for 16 years). The main thing that a Softw are  Engineer does is writing documentation for other Engineers and for  delivery to the Customer, to describe the software design and  explain how the software is installed and used, etc.

Roughly at  least 2/3s of a Software Engineer's time is spent on that, so  writing skills are a very high priority. The computer science discipline concerned with developing large applications. Software engineering covers not only the technical aspects of building software systems, but also management issues, such as directing programming teams, scheduling, and budgeting. Software Engineering is an approach to developing software that attempts to treat it as a formal process more like traditional engineering than the craft that many programmers believe it is.

We talk of crafting an application, refining and polishing it, as if it were a wooden sculpture, not a series of logic instructions. The problem here is that you cannot engineer art. Programming falls somewhere between an art and a science.

      There are two general approaches to engineering software. Both have to do with how software projects are managed. One approach is called the Waterfall approa ch. The other is called the Agile approach.

    In the Waterfall approach, the project moves through a series of stages. These are conception, requirements analysis, design, programming, testing, and delivery/deployment/distribution. A project timeline gets developed in which the time for each stage is estimated, and deadlines for each stage are set. Often a certain amount of extra time is added for unforeseen events.     In the Agile approach, a periodic cycle is set up, generally between two and six weeks per cycle.

Software Engineering Tutorial

During each cycle, most of the stages of the Waterfall approach get done to the extent that time allows. So in each cycle the team does analysis, design, programming, testing, and demonstration to the customer. At which point the next cycle begins by asking the customer what part they need to have done next.     The Waterfall approach is good when what is needed by the customer (requirements) is well understood up front, and is not likely to change. The Agile approach is good when either what is needed by the customer is not well understood (even by the customer), or requirements are likely to change during the course of the project.
