1. Analysis: |
As the web site is going to be a part of a system, It needs a complete analysis as, how the site is going to help the business. The first important thing is finding the targeted audience. Then, all the present hardware, software, people and data should be considered during the time of analysis
2. Specification Building:
Preliminary specifications are drawn up by covering up each and every element of the requirement. For example if the product is a web site then the modules of the site including general layout, site navigation and dynamic parts of the site should be included in the spec. Larger projects will require further levels of consultation to assess additional business and technical requirements. After reviewing and approving the preliminary document, a written proposal is prepared, outlining the scope of the project including responsibilities, timelines and costs.
3. Design and development:
After building the specification, work on the web site is scheduled upon receipt of the signed proposal, a deposit, and any written content materials and graphics you wish to include. Here normally the layouts and navigation will be designed as a prototype.
There can be a lot of suggestions and changes from the customer side, and all the changes should be freezed before moving into the next phase. The revisions could be redisplayed via the web for the customer to view.
As needed, customer comments, feedback and approvals can be communicated by e-mail, fax and telephone.
4. Content writing:
This phase is necessary mainly for the web sites. There are professional content developers who can write industry specific and relevant content for the site. Content writers to add their text can utilize the design templates. The grammatical and spelling check should be over in this phase. But also client will responsible as what those contents are.
Now its programmers turn to add his code without disturbing the design. Unlike traditional design the developer must know the interface and the code should not interrupt the look and feel of the site. If the site is dynamic then the code should utilize the template. The developer may need to interact with the designer, in order to understand the design. The designer may need to develop some graphic buttons whenever the developer is in need, especially while using some form buttons.
Unlike software, web based applications need intensive testing, as the applications will always function as a multi-user system with bandwidth limitations. Some of the testing which should be done are, Integration testing, Stress testing, Scalability testing, load testing, resolution testing and cross-browser compatibility testing. Both automated testing and manual testing should be done without fail. After doing all the testing a live testing is necessary for web sites and web based applications. After uploading the site there should be a complete testing(E.g.. Links test)
This phase is applicable only for web sites if client needs online marketing. Promotion needs preparation of Meta tags, constant analysis and submitting the URL to the search engines and directories. The site promotion is normally an ongoing process as the strategies of search engine may change quite often. Submitting a site URLs once in 2 months can be an ideal submission policy. If the customer is willing, then paid click and paid submissions can also be done with additional cost.
8. Maintenance and Updating:
Web sites will need quite frequent updating to keep them very fresh. In that case we need to do analysis again, and all the other life cycle steps will repeat. Bug fixes can be done during the time of maintenance. Once your web site is operational, ongoing promotion, technical maintenance, content management & updating, site visit activity reports, staff training and mentoring is needed on a regular basis depend on the complexity of your web site and the needs within your organization.
*The above-mentioned steps alone are not strict to web application or web site development. Some steps may not applicable for certain tasks. It depend on the cost and time involved and the necessity. Sometimes if it is a intranet site, then there will be no site promotion. But even if you are a small development firm, if you adopt certain planning along with this web engineering steps in mind, it will definitely reflects in the Quality of the outcome.
