This guide
This guide is an abridged version of the Guide to ABC in the CPS and provides a brief introduction to Activity Based Costing (ABC) and its uses within the CPS. Further information and more detailed explanations can be found in the full Guide.
What is Activity based Costing?
Activity Based Costing (ABC) is an internationally recognised system in which staff timings and costs are produced by breaking down each activity into its constituent parts to determine the work effort required.
This enables staff costs to be attributed to all activities within an organisation and provide a measure of the amount of resource used to undertake a specific element of work.
This in turn provides invaluable data to support any planning, monitoring and control system, enabling managers to make better and more informed business decisions.
If you cannot measure a task, you cannot manage it or, more importantly, improve it.
We are all involved in costing activities every day of our lives although we may not always realise it. When we pay for goods in a shop, we are part of a complex costing transaction that helps the manufacturer pay wages, heating, lighting rent, VAT, taxation and so on. Another portion of the payment goes to the upkeep of the shop we bought the goods in to pay salaries and support their continuance in the market place. Further elements will cover profit and possibly some shareholder dividend.
Pricing is a complex business involving a large number of people but the bottom line is always that the sale price has to be greater than the price of production.
Anyone selling lower than the cost of production will rapidly go out of business. This is why manufacturers know the price of every single part of their production process.
In the same way, faced with a wages bill of tens of billions of pounds, Government should also know the true cost of its 'product' at every stage, so that it can demonstrate its efficiency and prove that it is making best use of taxpayers' money.
For CPS, ABC means in-depth measurement of the prosecution process and timings attributed to those processes, to ensure equitable and fair resource distribution for all its business units.
Number of files handled * staff time = the cost of prosecution
What is an Activity Based Cost in the CPS?
CPS is not alone in using ABC. Most government agencies, particularly the bigger ones, use some form of ABC measurement, as do major companies, manufacturers, insurance companies, banks, retailers, building societies, airlines, universities, and so on.
The techniques of ABC are used all over the world wherever there is a work process to be measured or a cost to be determined.
Activity Based Cost Management identifies the factors that drive costs in organisations. It also measures and analyses costs in a way that helps managers understand better what influences their core business. It also helps them to exert control in achieving objectives.
An activity cost is simply a measure of the amount of resource used to undertake a specific element of work.
The broad concept of activity costs within CPS is that the number of cases handled, multiplied by staff time, is equal to the total cost of staff time spent on the CPS prosecution process. The system is built purely on staff time (as this accounts for around three quarters of the cost) and excludes accommodation and other costs, e.g. Capital expenditure or Counsel's Fees.
ABC does not replace performance indicators but illuminates them to make their messages more meaningful. Indicators on their own are rather like the controls in a car which tell you how many revs and what speed you are doing, but not if you are a good driver or are respecting the speed limit.
After all, the simple cost of a case can always be determined by dividing expenditure by caseload but this tells you nothing about the efficiency or quality of the product or how the organisation is running, only how much the case costs on average.
When you want this information, this is where ABC comes in.
Why are Caseload Finalisations important in ABC?
Although there are various techniques to measure and quantify work, an equally important element in the ABC system are Performance Indicators which act as Volume Counts, and tell us how many cases have been completed or defendants finalised. Knowing how long or how much money a case takes to finalise is useful but unless we know how many of them we have done in the past or will do in future, the information has limited use. In the ABC system, timings have been measured for types of case that Areas routinely count as part of the standard Performance Indicators package. The counts relate to the different types of CASE OUTCOMEin both magistrates' and Crown Courts. The table overleaf shows the various case outcomes which ABC uses and their relative costs
Why is it important to accurately record all cases dealt with?
The key factor in determining an Area's ABC share is its caseload and case mix, and so it is very important that all staff members are properly trained and aware of the need to correctly finalise all cases. Failure to do so could mean a reduced ABC share with a likelihood of less staff budget for the Area in future years, as well as distorting the true position on caseload.
Failure to do this could have an adverse impact of the future resources for your Area!
How can we ensure that we correctly record our case finalisations?
- Make all staff aware of the importance of recording case finalisations with regard to budgets / staff;
- Ensure that staff responsible for recording case finalisations are appropriately trained;
- Ensure that training needs are monitored with regard to case finalisations, especially when new procedures/policies or system upgrades mean that changes may occur;
- Regularly review your Area's system for ensuring that cases are finalised to reduce the risk of cases being overlooked;
- Complete regular dip sample checks to ensure that bad practice and incorrect interpretation does not creep in;
- Keep case finalisations under review – identify trends or anomalies at an early stage, investigate and question.
Some common problem areas
- Pre Charge Decisions and Consultations
- Specified offences
- Other proceedings
- Guilty verdicts as opposed to Guilty pleas
- Late finalisation of Crown Court cases
Remember - as few as 25 missed Crown Court finalisations each year can equate to a B1 caseworker in your ABC profile!

How does CPS use ABC or Determination?
ABC measurement was introduced primarily to address the need for a fair and equitable allocation of running cost budgets to Areas. Imbalances in staff distribution were common knowledge within CPS with many believing that those who shouted loudest got most, with other areas being disadvantaged. Use of ABC data offered the opportunity to distribute funds within CPS based on need rather than precedent.
So, ABC, within the CPS, is used as a resource distribution system, rather than a resource determination system. This means that the core prosecution process on the majority of cases in CPS Areas is measured in ABC. However, the work in other parts of CPS outside Areas is not covered by ABC models. In contrast, a resource determination system attempts to capture all activity and attribute costs to all activities/functions within an organisation. In this way the overall cost of an organisation meeting its objectives and obligations can be assessed but this will generally require more ABC personnel and a much greater level of maintenance and updating.
How does ABC distribution work?
In simple terms, an ABC staff profile is calculated for each Area. This staff profile is calculated by multiplying the ABC times to deal with different types of case by the volume of those cases dealt with in each Area. The total time required tells us how many staff at different levels is needed (as we know how many minutes per year equals one member of staff). The number of staff is then converted into £ costs by applying the average annual salary costs in each Area. So for each Area we can calculate a total ABC cost based on its caseload and case mix.
Aggregating these results from all the CPS Areas provides a National ABC cost. We can then determine what proportion of the National ABC cost is appropriate to each Area based on its ABC share. Finally each Area's ABC percentage share is applied to the actual funding available. For example, if Area A's ABC share of the National ABC is 5%, then it will receive 5% of the available funding.
This principle can also be applied when assessing the balance of staffing between different Business Units in Areas or if your Area is planning a restructuring exercise and seeks some indication of how to distribute existing staff. An easy-to-use Excel based package has been developed for this task and along with appropriate training, is available from the ABC Team, contacts at the end of this Guide or on the CPS Infonet (Home/Business/ Business Improvement/Activity Based Costing).
What does ABC cover and where is it used?
ABC currently focuses on the core prosecution process work undertaken in CPS Areas by both legal and administrative staff in levels A1 to D, excluding Area Secretariats and Group Operations Centres (GOC). This is where the majority of operational staff is based and where casework is more predictable and averages can be more readily applied. Associate Prosecutor activity is included within the timings but Higher Courts Advocacy is excluded as this is funded via other means at present.
ABC does not cover work in National HQs, Business Support Centres, CPS Direct who are allocated funding via alternative means. Cases within the Central Casework Divisions dealing with Counter Terrorism cases, Complex, Serious and Organised Crime (formerly Casework Directorate), as well as the newly created Complex Casework Units (CCU) in Areas, deal with cases of widely variable duration, and complexity, where application of averages would be unreliable, and thus do not currently have specific case timings for their work. Alternative measurement techniques such as time recording are being explored to capture costs here.
ABC deals only with payroll costs and does not encompass prosecution costs ie counsel fees, other general administrative or capital expenditure. ABC does not cover what is called "non baseline" funding which is provided to the CPS from other CPS sources for specific purposes or projects. For example, the introduction of Statutory Charging was funded via ring fenced funding for several years, until deemed to be "business as usual". ABC modeling allows for comparison to be made between calculated costs and the actual time and cost required to carry out the CPS caseload. It also produces a profile of the staff required by level for each Unit or Area. Existing staff-in-post figures, including agency staff paid locally or lawyer-agents can be set against this profile for management information purposes.
In addition, ABC data is used by the Ministry of Justice in the CJS Model used to inform the Home Secretary and Government in general, of the true impact of legislative changes on the cost of the criminal justice system. More recently, ABC data has also been used to populate various models developed by the Office for Criminal Justice Reform (OCJR) to measure the impact and benefits of key CJS change initiatives, including the Beacon sites "Waterfall" model.
ABC also provides support to many initiatives within and beyond the bounds of CPS, particularly in terms of business cases and benefits realisation for many of the CPS change projects eg Compass, No Witness No Justice, Charging and the Disclosure Project. Members of the team also work from time to time with Policy colleagues in assessing impacts of new procedures arising from policy change.
How does ABC measure work elements?
The following chart shows the key stages in building an Activity Cost.
Define the process to be measured
Fix start and finish points

Determine appropriate volume count(s)
For CPS equals - No. of defendants finalised

Flowchart the whole process as simply and clearly as possible

Break the work down into small elements or tasks

Allocate each element or task to a specific staff grade/level

Time each element or task

Analyse files or records to find out how often different activities occur, e.g. Hearings or Correspondence

Apply ALLOWANCES for Personal time, interruptions and management of staff

Produces an
ACTIVITY TIME

Multiply this by the number of cases to find the total time required for the caseload

Allow time for absence for sickness, Annual Leave and training

Add in time for travel to Court and police stations

To sum up
ABC provides CPS with a number of benefits:
- More equitable distribution of running cost resources/budgets to the 42 CPS Areas, based on their relative caseload and case type.
- More open, transparent (and speedy) system for allocating resources to a large number of stakeholders
- Meaningful performance management information for managers at all levels within the organisation, and beyond.
- Accurate operational costing on all aspects of CPS performance, and costing support for any "what-if" scenarios, or policy changes.
- Contributes on assurances to government and other bodies on CPS cost efficiency.
- Accurate costing of new proposals for CPS and support for business cases / benefits realisation work on all major change initiative projects and programmes.
- Identification and advice on the avoidance of inefficiencies within the CPS prosecution process.
- Essential information to other agencies (ABC is a leading contributor to CJS planning models) about the cost of common areas of concern – important in the Criminal Justice System where performance is often dependent upon other Agencies.
