When your PC has stopped working Cheap Nike Air Max TN Plus Australia , what you will want to do is simply to get it back up and running as soon as possible. But the question is, should you take it to a manufacturer-approved PC technician or to an independent one?


Making the decision regarding which PC technician you will be taking your PC to isn’t always a straightforward one, as not all manufacturer-approved services are better than the independent repairer, and not all independent PC technicians will work out cheaper than going to the manufacturer’s chosen technician.


One of the most important things that you should be looking at once you have tried the avenues available to fix your PC yourself is to find what qualifications and accreditations that your local technicians will have. The most successful PC technician will always be happy to discuss their qualifications with you, and will often include more details of these on any business cards or websites that their company has.


The most obvious benefit of going to a manufacturer-approved PC technician is that they will have had to go through some form of assessment set by the manufacturer in order to ensure that they are of sufficient standard. In a field where there are so many different qualifications which can be completed Cheap Nike Air Max 90 Ultra Essential Australia , and the standards of the varying qualifications are often difficult to compare, the manufacturer’s assurance on the skills of the technician can be a very helpful.


However, the benefits of going to an independent PC technician are also significant, where as a general rule, you will find that they have prices which will be more competitive than the manufacturer-approved option Cheap Nike Air Max 90 Hyperfuse Australia , and because they will frequently work with a wider variety of machines, and will also build PC’s, they can have a broad base of experience which will help them in repairing your PC.


One thing you should certainly be doing is asking around to see if anyone you know has used any local PC repair services, and what kind of service that they have received with that PC technician.


Ultimately, the choice will usually come down to whether you prefer the extra reassurance of using the manufacturer approved technician or the lower prices that you can get when you use an independent technician.


Did you know that maintenance accounts for 50% to 80% of the overall product cost? Well Cheap Nike Air Max 90 Ultra 2.0 Flyknit Australia , it does! And while most project managers are fairly good at sizing new product features, many are terrible at estimating the effort required to support a product once it becomes generally available. As a result, maintenance projects are inadequately staffed, companies can't respond to customer requests in a timely manner, and products never reach payback.


This article presents a methodology to help you guesstimate and therefore plan for the maintenance phase of generally available products. But first Cheap Nike Air Max 90 Ultra SE Australia , let's define a few terms that are important to the comprehension of this article.


Maintenance


Maintenance is defined as the effort associated with fixing defects in a software system after general availability (GA). In other words, how many person-months will it take your organization to fix bugs discovered by your customers in the field?


Maintenance can be subdivided in three sub-categories.


Corrective maintenance involves fixing bugs that are discovered in the system after it becomes generally available. An example of a corrective maintenance activity is a developer fixing a Java method that causes a compilation error.


Adaptive maintenance involves changing the system to work in a different environment such as a different network topology, platform, or operating system. An example of an adaptive maintenance activity is a developer fixing a Java method that works on BEA WebLogic but not on IBM Websphere.


Perfective maintenance involves changes that allow the software to meet the same requirements but in a more acceptable manner. For example, the designer might change some code simply to make the system more efficient or easier to maintain.


Enhancements


Enhancements Cheap Nike Air Max 90 Ultra 2.0 Essential Australia , also known as change requests, are defined as the effort associated with adding new capability to a software system, or modifying a software system to meet newly defined non-functional requirements.


Imagine an application that requires the user to authenticate using a username and password. Pretty standard stuff, right? Maybe, but some customers might want to add a third credential to the password mechanism such as a domain. Others might want the username to adhere to an email address pattern. Finally Cheap Nike Air Max 90 Red Australia , others might want the application to remember the user's credentials over sessions, thereby authenticating the user automatically.


Support


Support is defined as the sum of the maintenance and enhancements efforts performed after the product is GA. In other words, support includes all the activities that go on after a product is declared generally available.


Methodology


Early in my career, I realized that simple rule of thumbs could be applied to estimating the support cost of certain projects. For example, the annual cost of supporting a static Web site after it goes live is more or less equivalent to the cost of developing it. In other words Cheap Nike Air Max 90 EZ Australia , if developing a static Web site costs $10,000, you can expect to spend $10,000 per year maintaining it.


Understanding such rules is very practical. Unfortunately, few of them are transferable. In other words Cheap Nike Air Max 90 Black Australia , the same rule would not apply to an e-commerce enabled dynamic Web site distributed across 3 tiers.


Various models have been developed over the years to predict maintenance costs based on defect-density (e.g. Raleigh Curve, Weibull Analysis), KLOC and KDSI, and development efforts. Unfortunately, these models are not without any shortcomings either. Many of them are either highly inaccurate or too c.
