20150630 750 Disc Essay 20150630 750 Disc Essay The project I am working on at Mayo Clinic deals with improving flow within the Supply Chain Management Department. Specifically, I am working with the Master Data Management and Sourcing Pricing Quoting teams to document current flow and resource use to better determine a smoother system and uncover any gaps in research and processing. In healthcare there is a continual push for optimization and SWOT and force field analysis provide a valuable assessment of opportunities and barriers to change. Through this project I’m gathering data through SWOT and force field analysis before studying a focus group comprised of members of both teams. The SWOT and force field analysis provide the framework of opportunities through strengths and pushback from having weaknesses and opposition to change. 1) Define the Strengths, Weaknesses, Opportunities and Threats based on your analysis of your project. Explain your answer. Our strengths are determined by current elements and behaviors that boost our performance. After talking with several colleagues, one of the primary strengths within our department is proved success and a good reputation built from an experienced staff and involved leadership. Mayo is currently considered number two in healthcare supply chains according to Gartner. Another important strength is having the resources to make change. As a major healthcare supplier Mayo Clinic not only has purchasing power, they have the ability to work with development and build software that directly fits our organization. Weaknesses have to do with issues and behaviors within our organization that reduce or quality of care. We identified several weaknesses when thinking about how our teams work together and some barrier to change. Communication is a weakness among our supply chain. Although data travels quite well among teams communication about policy and procedure updates is not communicated or updated appropriately on team websites. Another weakness is trust among teams and team members. There is a lot of repeated verification of data as is flows through the system creating a lot of rework. Opportunities provide possibilities to make change developments that improve quality, efficiency, or lower costs. Several opportunities have also become apparent as the discussion has been opened up among teams. As both teams are newly staffed, there is a lot of opportunity to see how changes in the system can produce more efficient processes. We have also determined that defining roles and cross training could be very beneficial and support flexibility. Threats are influences that pose barriers to maintaining or improving the current state. Threats among our work teams include product disruptions for end users and decreased internal customer satisfaction as well as improper data reporting which can be very costly during annual audits. There are several other threats includ ing buying inaccuracy, and volunteerism among team members to embrace change and take on responsibility. 2) What are the opportunities for change? There is an opportunity for flow improvements as well as cross-training to improve data determination from end users. Mapping out the flow and identifying the best research tools to gather up-to-date, accurate information from within our system and from vendors should help to improve internal customer experience as well as build trust and teamwork. The goal is to reduce the time it takes from request submission to access to items. There is a secondary opportunity for developing better teamwork and communication through this process and outlining responsibilities. 3) What are the driving forces

Everything You Need to Know About Sandstone

Everything You Need to Know About Sandstone Sandstone, simply put, is sand cemented together into rock - this is easy to tell just by looking closely at a specimen. But beyond that simple definition lies an interesting makeup of sediment, matrix,  and cement that can (with investigation) reveal a great deal of valuable geologic information. Sandstone Basics Sandstone is a type of rock made from sediment - a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand  particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock. More precisely, sand is between 1/16 millimeter and 2 mm in size (silt is finer and gravel is coarser). The sand grains that makeup sandstone are aptly referred to as framework grains. Sandstone may include finer and coarser material and still be called sandstone, but if it includes more than 30 percent grains of gravel, cobble or boulder size its classified instead as conglomerate or breccia (together these are called rudites). Sandstone has two different kinds of material in it besides the sediment particles: matrix and cement. Matrix is the fine-grained stuff (silt and clay size) that was in the sediment along with the sand whereas cement is the mineral matter, introduced later, that binds the sediment into rock. Sandstone with a lot of matrix is called poorly sorted. If matrix amounts to more than 10 percent of the rock, it is called a wacke (wacky). A well-sorted sandstone (little matrix) with little cement is called an arenite. Another way to look at it is that wacke is dirty and arenite is clean. You may notice that none of this discussion mentions any particular minerals, just a certain particle size. But in fact, minerals make up an important part of sandstones geologic story. Minerals of Sandstone Sandstone is formally defined strictly by particle size, but rocks made of carbonate minerals dont qualify as sandstone. Carbonate rocks are called limestone and given a whole separate classification, so sandstone really signifies a silicate-rich rock. (A medium-grained clastic carbonate rock, or limestone sandstone, is called calcarenite.) This division makes sense because limestone is made in clean ocean water, whereas silicate rocks are made from sediment eroded off the continents. Mature continental sediment consists of a handful of surface minerals, and sandstone, therefore, is usually almost all quartz. Other minerals- clays, hematite, ilmenite, feldspar, amphibole, and mica- and small rock fragments (lithics) as well as organic carbon (bitumen) add color and character to the clastic fraction or the matrix. A sandstone with at least 25 percent feldspar is called arkose. A sandstone made of volcanic particles is called tuff.​ The cement in sandstone is usually one of three materials: silica (chemically the same as quartz), calcium carbonate or iron oxide. These may infiltrate the matrix and bind it together, or they may fill the spaces where there is no matrix. Depending on the mix of matrix and cement, sandstone may have a wide range of color from nearly white to nearly black, with gray, brown, red, pink and buff in between. How Sandstone Forms Sandstone forms where sand is laid down and buried. Usually, this happens offshore from river deltas, but desert dunes and beaches can leave sandstone beds in the geologic record too. The famous red rocks of the Grand Canyon, for instance, formed in a desert setting. Fossils can be found in sandstone, although the energetic environments where sand beds form dont always favor preservation. Grand Canyon National Park.

The grains become more tightly knit together, and the sediments are squeezed into a smaller volume. This is the time when cementing material moves into the sediment, carried there by fluids charged with dissolved minerals. Oxidizing conditions lead to red colors from iron oxides while reducing conditions lead to darker and grayer colors. What Sandstone Says The sand grains in sandstone give information about the past: The presence of feldspar and lithic grains means that the sediment is close to the mountains where it arose.Detailed studies of sandstone give insight into its provenance- the kind of countryside that produced the sand.The degree to which the grains are rounded is a sign of how far they were transported.A frosted surface is generally a sign that sand was transported by wind- that, in turn, means a sandy desert setting. Various features in sandstone are signs of the past environment: Ripples can indicate the local water currents or wind directions.Load structures, sole marks, rip-up clasts, and similar features are fossil footprints of ancient currents.Liesegang bands are signs of chemical action after burial of the sand. The layers, or bedding, in sandstone are also signs of the past environment: Turbidite sequences point to a marine setting.Crossbedding (truncated, tilted sandstone layering) is a rich source of information on currents.Interbeds of shale or conglomerate may indicate episodes of different climate. More About Sandstone Noppawat Tom Charoensinphon / Getty Images As a landscaping and building stone, sandstone is full of character, with warm colors. It can also be quite durable. The majority of sandstone quarried today is used as flagstones. Unlike commercial granite, commercial sandstone is the same as what the geologists say it is. Sandstone is the official state rock of Nevada. Magnificent sandstone outcrops in the state can be seen at Valley of Fire State Park.   With a great deal of heat and pressure, sandstones turn to the metamorphic rocks quartzite or gneiss, tough rocks with tightly packed mineral grains.
