  • Process Architecture Explained
    and a few minutes later it is cooked Simple yes Not so While the cooking of a burger may seem like a simple process it relies on the success of a whole number of inter linked processes to take place The patty needs to be processed at a meat rendering plant and transported to the restaurant before the cooking process can take place In addition to these basic processes there are any number of others that must go on behind the scene to result in a cooked burger quality control purchasing kitchen maintenance and a hundred other related processes These basic processes can all be grouped together into process systems high level inter dependent processes that require the success of each other in order to achieve their objectives Benefits of Process Architecture Process architectures provide visual representations of the processes and process systems within an enterprise offering executives and planners a birds eye view of the activities of the enterprise as a whole The benefits of this should be clear By gaining an overall view of the enterprise it becomes possible for planners to identify its strengths and weaknesses allowing them to identify areas in need of improvement and offering them the ability to develop strategy to best exploit the strengths of the enterprise Navigation Guide A process architecture serves as a road map by which process planners can devise best practices for high level and basic processes to ensure that all processes are aligned with the overall business strategy Automation Possibilities By using process management software from such vendors as InfoSys and Osellus to develop a comprehensive process architecture schematic it is possible to identify processes or steps within processes that could be effectively automated to reduce the burden on staff members and increase speed and efficiency Simplification Process

  • Product Lifecycle Management Explained
    must be developed with the marketplace in mind The initial phase of any product lifecycle will therefore rely heavily on customer data market research and focus groups What will the product need to achieve to succeed What does the customer require Where will the product fit in the marketplace The answers to these questions allow the designers to frame the technical parameters of the product Design Once a basic concept has been defined the product must be properly designed The design phase will usually be based within a CAD framework allowing developers to complete the process from design conception and refinement through to stress testing using a single software package The use of CAD software in the design and testing phases allows designers to make continuous adjustments to the design based on testing data something that would be much more time consuming when physically performed Realisation Once the product design has been finalised it is necessary to develop an efficient manufacturing process to make the best use of production resources Most enterprises will use some form of manufacturing process management MPM software to convert the Bill of Materials a list of necessary parts for the product into a Bill of Processes MPM software can also help in the design of the most efficient production line scenario reducing lead time to the product launch and minimising work in progress WIP inventories The realisation phase may also involve the use of computer aided manufacturing software to convert CAD product visualisations into operational code for numerical control machine tools further reducing the lead time Service The final phase of the product lifecycle is the service of the product Customers and service engineers must be provided with service information to allow them to repair or order the repair of faulty products While this phase

  • Program Management Software Explained
    order to minimise the risk of failure it is vital to ensure that the integrity of this project chain is protected and the most effective method of managing this task is to install a system by which the entire program can be managed Program management software provides a support structure for a layer of management focused on the administration of a portfolio of separate projects beneath Aspects of Program Management Software In order to synchronise and manage a range of parallel projects it is necessary to ensure that all projects within a program align with the goals needs and value proposition of the enterprise Program management software offers a suite of reporting and planning tools broadly based around the following areas Governance Programs require a much more complex governing structure than individual projects as their failure can have a much more significant impact on the health of the enterprise as a whole than the failure of a single project As a result program leadership will accommodate multiple oversight for the management of the program rather than the typical single management structure of the project Program management software will provide reporting tools for each member of this leadership group allowing them to monitor and track the progress of individual projects and the program as a whole Management Program management separates responsibility for the program across three layers At the lowest layer project managers coordinate the planning directing and controlling of company resources to achieve a specific short term objective In the middle is the program manager whose primary responsibility is to ensure that the individual projects align with the broader strategy of the enterprise This involves setting objectives and reviewing the plans of project managers to ensure that they conform to the broader program strategy At the uppermost layer is the

  • Project Management Software Explained
    personnel components paperwork have to come together at the right times to produce a smooth flow and ensure deadlines are hit and money s not lost There are plenty of software tools that can help with this kind of management from visual aids like Gantt charts and time sheet tracking to collaborative controls enabling whole teams to work better together These are the key types of Project Management Software Gantt Chart a type of chart which shows the relationships of the various elements in a project over time It can be used to monitor the progress of a project and to indicate which elements are crucial to meeting project deadlines PERT Chart PERT stands for Program Evaluation and Review Technique and offers similar functions to Gantt including easy determination of the critical path within the project Bug and Defect Tracking provides assistance in tracking the handling of reported errors or faults in physical or software products Time Sheet Tracking when project members are dividing their time between multiple projects time sheet tracking is used to record time spent on each task and issue time sheets for management approval each week month etc Group Management a general term covering aspects such

  • Rack Mount Servers and Computers Explained
    of course is where most rack mount servers are to be found but small and medium sized businesses can also make use of them It s not only seven foot tall racks that use the rack mount format There are many other smaller cabinets floor mounted or wall mounted that can take a couple of servers a network switch access point and a cabling patch panel as well centralising all the computing equipment in one place Once a company begins to grow to the point where they have a few small servers dotted around the offices with fans on permanently next to people trying to work and make phone calls a rack mount cabinet can be just the right move Racks of all shapes and sizes nearly always come with removable doors and side panels A closed cabinet can be best for an office environment because as well as keeping the noise in the computing and network equipment can be locked securing it from tampering either deliberate or accidental Server Configuration for Rack Mounting The server components that go into rack mount cases are not a great deal different from those that would be found in a tower or desktop case A server should be specified according to the work that it needs to do rather than the format of the case it is going to be put in Many major computer suppliers provide servers in rack mount format or they can be built into a case for bespoke needs The real difference when it comes to specifying components is that the space constraints of a rack mount case need to be taken into account Servers are available in many different heights and the lower the height the more computing you can fit into the available space But this also means that the cost of each server goes up as you will need specialist components to fit in the available space The standard unit of measurement for rack height is a rack unit normally referred to as a U which equates to just under 1 75 inches the height that covers three rack post holes So a 5U server which used to be the default size would be just under 8 75 inches more than enough to accommodate a normal PC motherboard along with a complete collection of expansion slots and cards and a number of disk drives and optical drives The measurements are always around 1 32 nd of an inch less than the full U height to allow room to manoeuvre equipment in and out of the racks Dealing With Smaller Rack Heights Increasingly servers have become smaller and now 1U servers are commonplace With 1U servers the motherboards are customised having the expansion slots raised and pivoted ninety degrees so that expansion boards can run parallel to the motherboard It is also not unusual for the voltages delivered around the boards to be lower than usual around 3 3v rather than 5V This is because lower voltages

  • What is RAID 0? Striping and RAID O explained
    It takes only one drive to fail and the entire array is affected Performance on RAID 0 is better than having a single drive as the work is split between the array drives Identical drives are recommended for performance as well as data storage efficiency so it is recommended that you use not just the same make and size but even the same model number You need a minimum of two drives to form a RAID 0 The disk array data capacity is equal to the number of drive members times the smallest member capacity For example one 1GB and three 1 2GB drives will form a 4GB 4 x 1GB disk array Stripe Size a value can be set from 1KB to 1024KB sector size The size can directly affect performance If you are dealing mainly with small files you may want to use an 8KB sector size whilst for Server and Audio Video Editing which typically use large files recommended sector size is 64KB From ACNC RAID 0 implements a striped disk array the data is broken down into blocks and each block is written to a separate disk drive I O performance is greatly improved by spreading

  • RAID 1 (mirror RAID) Explained
    two copies of the data simultaneously on two separate drives This is called fault tolerant because if one of the mirrored drives suffers a mechanical failure e g spindle failure or does not respond the remaining drive will continue to function The RAID 1 configuration is performed either by a hardware RAID controller or performed in software It is suited to applications requiring high fault tolerance at a low cost and where a duplicated set of data is more secure than using parity RAID 1 is popular for accounting and other financial data It is also commonly used for small database systems enterprise servers and home PCs where a fairly inexpensive fault tolerance is required A RAID device maintains a mirror of all the data in a partition on another partition This second partition is usually on another drive note in Linux systems the second partition can be on the same drive There is a small performance hit to be expected when configuring your hard disks in a RAID 1 partition as the data has to be written to every disk in the RAID array Wikipedia More information on RAID How to install RAID 1 on a Linux system RAID

  • RAID 2 Explained
    level 0 to level 6 although there are numerous other non standard hybrid and enhanced variants The data security methods usually involve one of three methods mirroring i e having the contents of one disk copied to another disk every time a change is made striping where data is spread among a series of disks or error checking where calculations are made on the data and the results stored to be checked against later RAID 2 Error Checking RAID 2 uses just this final method error checking and is rare among the standard RAID levels in that it does not marry it with any mirroring or striping It uses an algorithm known as the Hamming code after its inventor Richard Hamming an American mathematician and computer expert Each byte of data has a corresponding code constructed to match it which can be used not only to indicate that its byte or word has been corrupted but also in some cases allow the drive controller or disk driver to rebuild the data in its original form These error codes are then stored on a different disk to the data they refer to and the RAID 2 controller keeps tabs on which error code relates to which data segment Redundancy was built into RAID 2 but an array could only recover from the loss of one drive if another one failed that would be the end of the whole array which would have to be taken off line and the data rebuilt from archives or backups Why RAID 2 Didn t Make the Grade RAID 2 is at the time of writing no longer being actively developed and no products based on it have come to market for over a decade RAID 2 never caught on in the first place because of
