What Is The Difference Between ERP And Enterprise System?

Enterprise system and Enterprise Resource Planning System terms are similar but there is difference between an enterprise system and an ERP system. An ES or enterprise system is a large scale system which includes packages like ERP and CRM. ERP is a subset of Enterprise System or it can be said that ES is a superset of ERP. It contains a variety of solutions. ES contains applications and packaged solutions which can be directly used in an enterprise. On the other hand ERP system is the automation of the business processes and the solutions are in the form of modules which are designed according to the client’s requirements.

The functions are customized according to the client’s business environment. Enterprise system does not include architecture of other solutions whereas an ERP implementation automates systems using technical aspects. ERP system includes architectures and databases and is client server architecture. The system is server based therefore the consultant needs to be aware of the technical aspect too.

Another difference between an ES and an ERP system is that the ERP is aimed at improving the functionalities of the organization whereas the ES helps to improve the overall maintenance and accuracy. It provides for better solutions and aids in decision making. ES is difficult to implement compared to Enterprise resource planning and even the timeframe needed for implementation maybe more. The overall impact is high but so are the risks involved. If the ES is not implemented in the right manner, it can cause business failure and if implemented properly it can increase the efficiency and profits of the business organization. It is normally required when there is a big drawback in the current procedures and methodologies in the organization and need to be corrected. The company going in for enterprise system needs to be careful while choosing the software and the vendors due to the risk of failure involved.

The difference between an enterprise system and an ERP system is that ERP is mostly used for medium scale companies to big companies and ES is restricted to the big companies. There are many complex functions involved in big companies which cannot be provided solutions for alone by ERP. The role of ERP is restricted when compared to enterprise system because it does not include customer relationship or vendor management.

These applications are needed when the business process is complex and on a big scale. Therefore bigger organizations need to go with ES instead of enterprise resource planning alone. ERP is also an important system to streamline the internal processes but it does not provide for taking care of the external processes. Enterprise system takes care of the end to end business process of organization since it involves other applications also like SCM and CRM. There is quite a lot of difference between an enterprise system and an ERP and it depends on the company whether it wants to go with an ES to streamline the entire process starting from supplying, production and customer or whether he wants to go with an ERP system to streamline the internal process.

Strengths and Weaknesses of Waterfall Approach for Software Development

One of the most famous and widely used approaches for software development is the waterfall model. Waterfall approach is an old technique that has been in use for quite some time, but in modern times agile approach is gaining prominence.

Waterfall approach, as is evident from the name, refers to a systematic approach where one step comes after the other. It cannot go the other way round. The process works like the waterfall effect that flows in one direction, which is from up to down.

In this process the life cycle of the development process is predetermined. All the steps are defined before the start of the project. The approach is predictive, where the team is well aware of the order of each step and therefore works accordingly. It starts from the requirement analysis, the design phase and then proceeds on to the implementation, testing and the maintenance phases.

The waterfall approach can be quite beneficial for those who are quite clear on their requirements. A planned approach works for them because they want fixed processes and budget. Where fixed processes are beneficial, at the same time they can be inconvenient at times. In cases where the client is not clear on the requirements and finds in the middle of the project that he/she wants to change course, this approach can prove to be quite problematic.

Another point of the waterfall approach is that the requirement analysis and design of architectural structure can consume a lot of time. Extensive research is done initially as the next phases depend completely on the planning strategy. However, the good thing is that everything is thoroughly worked out and each aspect is studied beforehand. The developers in such cases know what is expected of them.

A waterfall approach works in a systematic order, with one step following the other and the testing phase comes in the end. If there are any big problems encountered in the testing phase, it means a long process to make the amends. The process can consume extra time and money.

We cannot conclude that one approach is better than the other, as every method would have its own strengths and weaknesses. The determination of success for each method depends on how it is being used and whether the approach suits the scope of work being undertaken. While one approach may be suitable for a particular project, it might become totally useless under different circumstances. For example, some believe that agile methods are not well suited for offshore development, as they require a closer contact and communication that is not possible in an offshore project.

The Advantages and Disadvantages to Bug Tracking Software

Bug tracking has been around as early as the 1940’s, just not in a software form. In these early days, simply using a pen and a paper created tracking systems. It evolved from then to using spreadsheets. Now there is bug tracking software like the defect tracking tool and even more specific programs like Mantis and Bugzilla, just to name a couple. As with anything that evolves however, there will always be those that are 100% for the programs and those that are against it. This article will cover all claims – both positive and negative – of bug tracking software like the defect tracking tool.

The Positive Claims

It certainly depends on the type of bug tracking software that is used, but it seems as if there are many more advantages to these tools than disadvantages. The most obvious advantage is that these types of tools allow companies to keep a record of the issues that are recorded, who fixed them, and even how long it took to fix the issue for some types of programs. Customers are encouraged to be as detailed as they can be when requesting that an issue be fixed so that companies can complete their requests as quickly as possible. The fact that the issues are recorded and saved is a huge benefit for the companies because sending the recorded bug list with the purchased software is a common practice. This is a benefit to customers because if it is a common error, they can simply look up this issue in the previously recorded bug list. However, if the list is incredibly long (a common disadvantage) it can become more of a hassle.

The Negative Claims

As with anything that has a list of positive aspects there is also a list of negative aspects, though there are few. One of the biggest complaints is not so much from the bug tracking software or defect tracking tool itself but more from the process of submitting issue requests. Customers need to be extremely detailed with their issue requests if they want a detailed response. Miscommunication isn’t a fault of the product, the customer, or the company – it’s simply something that happens. Customers and companies alike both need to remember to be patient with each other and to treat each other with a mutual respect. A second complaint that was previously mentioned is the length of issues in some of these software programs.

Some customers don’t have the patience to look through a long list of software issues that have been previously recorded and this causes frustration among the companies that took the time to purchase software that saves them. The length of issues that are submitted can also become a problem because if there are too many issues submitted and not enough engineers to address them, some can get overlooked. Nobody likes to be forgotten, but usually these types of bug tracking software include detailed instructions and are easy to use.

Usually when a company purchases a bug tracking software or defect tracking tool it already has an experienced IT department in place. Whatever the software is that is being used with these programs should have some sort of backup for when the work is completed so it does not get lost if the issues that occur are deadly.

Medical Coding History – From Paper to Medial Coding Software

If we define medical coding as the assignment of alphanumerical characters to diagnoses, diseases, and treatments, then medical coding has been traced back to the 1600s in England with the London Bills of Mortality. A more standardized system of coding was developed for classifying death at the tail end of the 19th century. In 1893, Jacque Bertillon, a statistician, created the Bertillon Classification of Causes of Death, a system which was eventually adopted by 26 countries at the beginning of the 20th century. Shortly after the Bertillon Classification system was implemented, people began discussing the possibility of expanding the system beyond mortality as a way of tracking diseases.

By the middle of the 20th century, the World Health Organization (WHO) adopted a goal of a single global classification system for disease and mortality, entitled the International Classification of Diseases, Injuries, and Causes of Death (ICD). This classification system is updated every 10 years. The latest revision, ICD-10, is scheduled for adoption in the United States in 2013.

What started out as a small set of medical codes has evolved into a complex system that was initially standardized by the American Medical Association back in 1966 with current procedure codes (CPT) codes that are updated annually.

In the late 1970s, the Healthcare Common Procedure Coding System (HCPCS) was developed based on CPT. HCPCS has three levels of codes: Level One is the original CPT system. Level Two codes are alphanumeric and include non-physician services such as ambulances and other transportation as well as patient devices such as prosthetic devices. Level Three codes were developed as local codes, and were discontinued in 2003 in order to keep all codes relevant worldwide.

Recently, medical coding systems have been expanded to include other medical specialties. For example, there are coding systems related to disabilities, the dental field, prescription drugs, and mental health.

As the coding systems have become more complex and diverse, the need for training of medical coders has grown exponentially. Private training schools and public colleges throughout the country have developed certification programs. In order to be awarded a certificate, students must obtain a two-year degree from an accredited medical coding school and pass an exam given by the AHIMA.

Over the past 20 years, many coding processes have shifted from a paper-based system to a computer-based system using medical coding software and medical billing software. Many companies sell complete medical software-based coding solutions and myriad of products for specific medical disciplines, such as products that are specifically tailored to skilled nursing facilities, physicians, hospitals, surgery, cardiology, and more.

As medical facilities and professionals begin preparing for the conversion to ICD-10 in 2013, the need for more sophisticated medical coding software solutions and qualified medical coders will continue to grow.

CPT is a registered trademark of the American Medical Association.
