Erlang 'C' & Scheduling for Call Centres - III

Skill Based Routing - simpler to say than actually execute, SBR is way of ensuring that your contact reaches the agent best suited to deal with and address their issue.  This assists in first call resolution, but is also key when it comes to things like languages and specific technologies.  An easy example is ensuring that a French speaking customer with a data problem reaches your agent in your call centre in Montreal (or France for that matter) vs your agent in an English speaking call centre.  Skill based routing allows for significant granularity and focus, but it is only as good as the information you know or are supplied with from the customer.  This can either be from an existing customer database or from your initial ACD (Automatic Call Distribution) system where the customer is responsible for determining what problem they have.

Scheduling Tools - there are a multitude of free & paid for scheduling tools available and obviously you get what you pay for with the ones requiring a monthly/yearly fee offering significantly more tools and services than the free ones.  However, depending on the size of your centre and your budget, some of these free tools (reviewed) are extremely effective and useful.  I have provided links to some of the better subscription based tools also, but have not included a review of them as their websites are fairly descriptive in and of itself.


  • Excel (or other) Spreadsheet - hopefully your budget includes at least one copy of Microsoft Excel, but if not, you can still get access to free spreadsheet applications either through Open Office or even Google Docs or Zoho Docs. Depending on your chosen product/solution, the formula's and look of the product will be slightly different, however for simple call/support centres any of these will suffice. Your main measurement would be determined from your total required staffing level. You can also build a schedule based on specified Tier's of customers or skillsets. Don't get too complicated with Excel as it would pay you to get a specialized tool to do this right. A sample Tiered schedule is provided below.

The key things to note here are that, there are less Tier2 staff than Tier1 (think about it as a Pyramid shape ... the higher up the Pyramid you get, the more skilled your staff are). And also, the GAP ... this is where you can expect to receive more calls/emails/contacts than your Staff are able to handle. Expect complaints, bad service and abandon calls as well as ... you should expect to start losing Customers! ... unless you can get this to be '0'

One other thing to note, is that this is a daily schedule ... see what I mean about specialized tools?  Don't worry I'll be getting to them soon I hope!

The Difference Between Incident Managment and Problem Management

Incident Management and Problem Management are both key components of the ITIL service model and have been defined and created in an effort to provide a better and more streamlined service to consumers.
ITIL itself stands for the - Information Technology Infrastructure Library - and comprises of the following books:
ITIL Service Strategy ITIL Service Design ITIL Service Transition ITIL Service Operation ITIL Continual Service ImprovementIncident Management and Problem Management are both elements of the fourth volume - ITIL Service Operation, which tries to define the best practice for dealing with interruptions to a customers service. What is an Incident? An incident is a single - unique - issue impacting one specific customer and their service. While there can be many similar incidents impacting multiple customers, each of them are in their fashion unique and need to be logged and treated as such.
An example of an incident is you losing your home Internet connection. While the underly…

What is PRINCE2

PRINCE2 stands for PRojects IN Controlled Environments and is a very popular method for effective Project Management.  PROJECT MANAGEMENTWhile PRINCE2 is one way of managing Projects, it is worthwhile defining what exactly a project is and why it needs management in the first place! 


A project is specific task/role that needs to be completed to meet certain objectives. In a managed project, you would have a defined beginning and end and certain "check points" throughout the process itself to ensure that you were on target to meet your overall objectives.

These checkpoints are referred to as "gates" and at each gate, you would have certain deliverable and targets to check your progress against. By managing a project in this fashion, you are able to ensure that you stay on track and that any issues or concerns are identified and dealt with at an early stage of the process versus waiting till the end.

The defined "end" to a project is necessary as it creates …

THE 4 P'S OF SERVICE STRATEGY

Competition is extremely fierce in the world of business, only a handful survive, and some can barely keep up with the demands of the times. That's why it is necessary to have an idea of what it takes to be successful and an integrated strategy to help maintain excellent service results.

ITIL discusses at length the four “Ps” of strategy- perspective, position, plan and pattern, each of which represents a different way to approach your service strategy. Brief summaries are provided here: Perspective - This is basically the vision statement of an organization.  Why is it in business, why is it doing what it is doing?  What are the plans and ideas for the future and how does the organization interact with its customers?  A perspective cements a service provider’s distinctiveness in the minds of the employees and customersPositions - What is the competitive landscape and how will the organization compete with other similar providers?  What is the key distinction between them and oth…

8 RULES OF GOOD CUSTOMER SERVICE & 8 STEPS TO DEFINE A SERVICE

In a similar fashion to interviewing and hiring people - the hardest and most expensive exercise is getting the right employee - getting people back into the door is exactly the same.  You want that repeat custom as that is what will save you money in your marketing and advertising.  One of the key components to this in addition to the quality of the product itself is the customer service that you provide to the customer in their purchasing and ordering decisions.  You can offer promotions and slash prices to bring in as many new customers as you want, but unless you can get some of those customers to come back, your business won't be profitable for long. Good customer service is all about bringing customers back. And about sending them away happy - happy enough to pass positive feedback about your business along to others, who may then try the product or service you offer for themselves and in their turn become repeat customers. 
Good customer service should be thought of as re…
