    Hi all.
    I wonder if you could all help me, I am interested in finding out how many are implementing ITIL Availability Management within their company service delivery and service management Framework.
    If Av Management is not being utilised, is it due to lack of knowledge, training, expertise, etc?
    If Av Management is being used, to what level is it implemented and what standard tools, processes, procedures, work instructions and software packages are being used.
    Many thanks for your help.

    Thought i’d start off……
    Within my role within Availability Management we have fully ISO20K acreditation.
    We carry out the following analyses in order to satisfy Customer requirements and deliverables….
    Functional Block Diagrams, Fault Tree Analysis, Service/Sub-system Level Component Failure Impact Analysis/FMEA
    We carry out the following analysis to satisfy in-house Service Management requirements and deliverables
    Functional Block Diagrams, Event Tree Analysis, Cause and Effect Diagrams, Equipment Level Component Failure Impact Analysis/FMEA.
    We use Isograph Reliability Workbench for FTA work and calculate the Service Level Availability. It can also be used to calculate the Frequency of Severity levels using Event Tree Analysis.
    We also do availability trending and forcasting.
    Kindest Regards

    Mark,
    In regaurds to Isograph Reliability Workbench, Have you seen or tried Mentorsoft? Take a look at this and the cost and let me know what you think. Its at this link http://www.dbar-innovations.com Let me know,Thank you.

    Hi Vincent.No I haven’t come across that piece of software. It seems to be a generic application for carrying out Six Sigma. I could not find any tools in there for carrying out Cause and Effect, Fault Tree Analyis nor FMEA.Reliability Workbench is purely a reliability application with which reliability predictions, reliability block diagrams, FTA, Event Tree Analysis and FMECA can be carried out to the level required by the user.I therefore wouldn’t like to pass comment on this application apart from that it doesn’t seem to do the work that I would want it to do.Mark.

    Sorry for replying so late.  I also missed all this, I know for a fact it has these to offer. Pareto totals, Pareto anaysis,box plot, FMEA, tree diagram, cause and effect matrix, run chart, multi vari, value stream map, Force feild analysis, process flow diagram, SIPOC, COPQA, gauge R&R, bias, capability analysis, regression analysis, area audits, top level map, process layout, process interveiws, cause and effect diagram,  1 factor, multi factor, 1 variable factor, functional flow, time studies, monte carlo simulaters, 1 factor modeling, 1 factor linear modeling, I-MR Chart, X-Bar & R, X-Bar & S, C-chart , U-chart, NP-chart, P-chart, Minitab tutorial, video guidance of the methodology with demonstration of the analysis tools, point of use templates, exaple data from 10 differnt projects in each step for training, multi project tracking and management system and just a few more things.  One day when you get more time you might want to take another looksie.

    Hi VincentIn the FTA portion of this application, how does this package calculate the reliability/availability of a system? Using Monte Carlo theory, Probability Theory?To what standard has the FMEA portion been created? Mil-STD-1629, Six Sigma?Many thanks

    This software system calculates the reliability/availability using various methods depending on the situation. As an example, reducing constraints caused by machine availability would more than likely use Monte Carlo simulation as a predictor, however it may also use a value stream  map as a vehicle for data colections. In regards to reliability or product life, various survival and reliability analysis may apply. 
    In regards to the FMEA portion of your question, it aligns with standard Six Sigma training.
    If you have any further questions, why dont you email me at [email protected] . I have been using this system for about 8 months. I can not imagine what this system is not capable of doing. I can tell you that the manufacturer is very flexable and have the ability to customize this to your specs and requirements as they did for me. It has the ability to integrate with existing programs and honestly, all I can do is speak for my own success, which is, it pulls every one in the same format, relieves memorization, and speeds up my cycle time reducing my time for project completion. I feel like the spokes person for this and the only reason I care is they gave it to me for free as a gift when I was in Black Belt training , the instructor at the class could not understand why I was able to absorb this so fast and I showed this to him then he got the company to purchase a site license. All in All, I think if you contact these guys directly you can get a demo and they can speak for their product better than I can.
     http://www.dbar-innovations.com  otherwise I am happy to help you with what resources I have and what little time I have  available. Thank you, Vincent

    Hi Vincent.
    Many thanks for the information. Sounds like a very good application for analysing and improving processes and meets the Six Sigma tool set.
    The problem I have is that, because Availability Management under the ITIL banner is relatively immature and is still being developed, there is not 1 application that will do everything that is required to provide a ‘Cradle to Grave’ Availability solution. For example, there are lots of network design tool out there that calculate Availability/Reliability of the service, but there is usually loads of resillience built into the system because of the paranoia that a failure will cause loads of financial penalties. Therefore, the availability prediction of 99.999999% is not adding value to the actual in-service operation and predicting the potential number of incidents/failures that needn’t affect user service but maintenance will have to work to get the equipment up to full functionality again.
    At the end of the day, there are loads of applications out there that will do lots of things.
    Personally, Apart from using Isograph RWB for calculation validation, I am using Visio for all of the Ishikawa and FTA and Excel for my reliability calculations.
    The reasons
    (1) because it can be easily shared without the other person having to either have the application or for the application to export into a format that can be read easily.
    (2) it can be easily be put into documents created in Word.
    I’ll PM you with my details.
    I do hope that this helps someone out. At the end of the day, it all comes down to personal preference, experience, budget and time.
    M:)
