The primary aim of warehouse management information systems is to monitor and control the movement and storage of materials within an enterprise along with processing the transactions related to these items. These systems involve extensive tracking of warehouse management information such as quantity, unit of measure, and location and coordinating these factors with where to stock, where to pick, and in what order to perform each. As you can well imagine, the question of whether or not one is even a true advantage to an operation and how to set one up and implement it is complex. This article will examine what the professed benefits are of warehouse management information systems, the reality of what they can do, and some important considerations when setting them up.Like many other software solutions, warehouse management systems have evolved through a number of phases over time. What has become obvious is that there is an overlap between warehouse management systems and other functioning systems such as supply chain, distribution, transportation, and scheduling. Understandably, this has created some uncertainty and indecision for companies seeking software solutions to their warehouse management. Despite this, there are a number of theories as to how these systems can add to the profitability of an enterprise. Among these claims are that warehouse management systems will improve inventory accuracy, storage capacity and customer service while  reducing inventory and labor costs. These are powerful incentives indeed, but what is the reality of using these systems?Over time, it has become evident that some of these advantages are more likely to manifest themselves than others. First let us look at what the true primary benefits are. By using WMS along with automated data collection, you are more likely to reduce cycle times which can translate into greater capacity to deal with customers. Beyond this, there are a number of additional functions such as lot tracking and yard management that can ultimately enhance customer service.  It is also likely that the increased accuracy and efficiency resulting from these systems can cut labor costs, provided the labor expense outlay to run the system is less than the labor on the warehouse floor. However, when it comes to reducing inventory storage capacities and amounts, the impact is less likely to take place. The reason for this is that the factors that effect inventory size and capacity such as lot sizing and lead times are not impacted by warehouse management information systems.While WMS provided the means for improving the organization of storage, the overall improvement seen will be more a result of how inefficient and disorganized the storage system was previously. Every new solution has it's drawbacks and implementing warehouse management information systems is no different. By adding WMS to your organization, you are adding another level of technology and will inherit all the challenges associated with it. These potential problem include the cultural changes necessary within your organization and added overhead expenses at the onset. These obstacles should not diminish the added functionality of WMS which lead to greater ability to compete and meet the needs of the customer. It is important to note that the design of WMS are very data reliant and restrictive in nature. It is there highly specialized nature that allow management to gain better control of their operation. The set up requirements can be extensive. It is absolutely essential to have every data element of the system intact and ready to be accessed in order for the the system to perform as desired. Once in place, there are set measurements that they must operate under. As with the implementation of any sotware system, the keys to success are testing, training and continuous evaluation.With all the advantages, disadvantages and set up and implementation considerations, the question remains, does a given organization really need a warehouse management information system? They can be big, complex and data intensive. In the case of a larger company, it may even be necessary to set up a seperate department to monitor them. It is only through careful evaluation can the decision be made to take on the added expense and personnel resources to reap the benefits down the road. These benefits can be enourmous as they encompass becoming a preeminent authority in an industry by enhancing the  ability to serve a market. By excelling in warehouse management,you are demonstrating a proven ability to deal with a complicated, continuous stream of details. This same ability will serve you well in all facets of your operation, and is indeed worth cultivating.
