Noonan – Enterprise Architecture Review and Business Process Mapping


The Challenge

Noonan is Ireland’s largest cleaning and security services company with a turnover of €146M in 2012. After a period of intense growth following a management buy-out, Noonan recognised that their existing IT services were struggling to keep pace with the needs of the business. A Noonan IT strategy recommended looking at the following options:

  1. Replacing existing applications with an ERP solution obviating the need for integration between them.
  2. Upgrading the current system landscape and leaving the current point-to-point integration between systems.
  3. Upgrading the current applications and introducing middleware to reduce and consolidate the integration points.

Noonan were unsure what path best suited the organisation and due to recent challenges with internal IT systems implementations were wary of large-scale changes.

Our Approach

ASE performed an enterprise architecture review using The Open Group Architecture Framework (TOGAF) and recommended transition from Noonan’s current set of disparate systems to a single ERP solution.

ASE assisted Noonan by:

  1. Defining a vision for Noonan’s future state.
  2. Providing Noonan with a set of tailored architecture principles to help drive future decisions.
  3. Understanding and describing a largely un-documented current state system architecture liaising with vendors and Noonan staff to achieve this.
  4. Determining the core Noonan systems and analysing their relationships and interfaces.
  5. Highlighting process issues in the current state and providing recommendations for how to improve these in the short term.
  6. Determining the underlying cause of issues in previous system implementations.
  7. Analysing the relative merits of the options proposed by the IT strategy including their architecture implications, feasibility and the likely cost of each option.
  8. Creating a future state architecture for an ERP solution with recommendations across the TOGAF architecture domains of business, applications, data and technology.
  9. Describing the issues, risks and migration considerations for the recommended approach.
  10. Providing recommendations on governance and change control.
  11. Performing a high-level enterprise architecture maturity assessment to help Noonan understand where improvements could be made.

ASE helped Noonan understand that previous IT system changes had encountered difficulties due to a lack of business change support to back up the IT enhancements. As a result of this, a separate stream of work was established to document the current state processes and provide a set of recommended future state process maps.

As part of the business process work ASE have completed:

  1. A breakdown of Level 1 and Level 2 process across the organisation.
  2. Determined the priority processes that will be mapped in the current and future state.
  3. A business process maturity model assessment to determine both Noonan’s overall process maturity and the relative maturity of processes in each area.
  4. A framework for mapping out more detailed Level 3 processes.

The Results

Following ASE’s presentation of our enterprise architecture findings to the Noonan board, Noonan have commenced procurement of an ERP solution and are commissioning ASE to continue with business process work to document the current and desired future state processes in more detail in advance of the ERP implementation.

Enterprise architecture artefacts developed by ASE are being used by Noonan to help drive understanding of the current state architecture within the organisation and as a basis for procuring an ERP solution.

Noonan have also asked ASE to provide consultation on their architecture as part of the ERP procurement.
