  • Seven Consulting played a lead role across multiple releases, including deployment planning and execution.
  • Seven Consulting also led the development of the CBA’s COSSE (Customer Offer Sales and Service Engine) system, enabling CBA to market offers for products, using differential pricing, to individual customers in semi real time.
  • Seven Consulting managed the warranty and defect processes as part of the program close-down.

  • Standardisation and Industrialisation with 105 re-usable and interoperable capabilities

Addendum: Customisation vs Configuration

The Chief Information Officer’s (CIO) job has never been tougher. Demand for information technology workers is at an all-time high and far exceeds the supply of skilled people.

There are several options;

  • buy a commercial off-the-shelf (COTS) product from a vendor and integrate it into your environment
  • build your own application
  • try to minimise your involvement by using an Application Service Provider (ASP) (a company that offers individuals or enterprises access over the Internet to applications and related services that would otherwise have to be located at the client).

Selecting a COTS product seems to be the easy answer. It avoids the lengthy development cycle associated with building an application in-house, and the inherent security risks of using an ASP.

To do this successfully;

  • Pick the “right” product from the list of possible solutions. As part of that process, identify the technical capabilities that are “must haves” versus those that are “nice to have.”
  • Conduct a gap analysis of differences between user procedures and product adaptability. It is reasonable to consider re-engineering processes and eliminating less urgent requirements in order to use a COTS product.
  • Focus on getting the product installed and integrated with the rest of your information systems. Most sophisticated applications require at least some data exchange with other application systems. No two integration efforts are exactly alike. The one thing you can count on is that integration costs both time and money. In many cases internal development may be unavoidable, as custom software is required to “glue” the various COTS components together.
  • One thing to avoid is Customisation of the COTS product, instead of spending time and money changing a commercial product, consider changing your internal processes and / or configuring the product

For CBA’s $1.4B Core Banking Modernisation program, Seven Consulting were involved in capturing metrics on customisation of a COTS product – SAP Banking.

The CEO, Ralph Norris, set a target that customisation of the COTS product should not exceed 10% of the requirements. The program team were required to manage to this target, measure adherence to it, and report back to the CEO on a monthly basis as part of a balanced scorecard report.

The target of less than 10% was defined as the percentage of non-standard requirements, i.e. requirements not met through “out of the box” functionality. This is calculated by totalling non-standard SAP Reports and non-standard SAP Extensions (i.e. modules) and measuring these as a percentage of Total SAP Business Requirements.

Some of the key activities required to keep the customisation level to appropriate levels included;

  • A review and understanding of “standard processes” offered by package
  • Adaption of current business processes to align with these out of the box offerings
  • Set-up and monitoring of a process to accept deviations from the “Standard”
  • Product release and upgrade planning to ensure accepted deviations do not impact future standard upgrade options

The adaption to the Standard impacted all phases of the System Development Life Cycle. Examples of these include;

Planning phase:

  • Inclusion in the business case of tolerance levels for product customisation
  • Strategic engagement with the Vendor to include into the Standard geographic customisations required for Australian conditions – for example Australian tax laws

Analyse phase:

  • Design workshops to focus on what exists in Standard, and highlight opportunities to challenge past history to reduce need for change of standard
  • Focus on key architectural directions to ensure alignment, and not drive need for exceptions

Design phase:

  • Changes to measurement metric to ensure design stays within desired parameters. Ensure exception decisions are escalated and clearly visible in design documentation

Build & Test phase:

  • Ensure build and testing ensure future upgradability is maintained

Deployment & Run phase:

  • Ensure package upgrades (service packs and main releases) are keep current and aligned with set policies

There was also a key opportunity that existed in initial contract negotiations for the COTS product to ensure that either geographic region customisations or on program advancement of the product was included back into Standard by the Vendor, thereby reducing future costs of customisations.

Based on this executive level relationship, and a strong working relationship with the Vendor, a result of 7.5% was achieved.
